How to apply rain x automobile windshield treatment

After using the Rain X Windshield Repair Kit to fix your cracks and chips, sometimes residue resin leaves a film on the windshield or car window surface. It is just as important to know how to remove Rain X film from your windshield as it is important to know how to apply it. Here are five quick and easy steps that will teach you how to remove Rain X film from your windshield or car windows. They do not require a lot of time, money or material. The process is so simple that anyone can do it.

How to apply rain x automobile windshield treatmentHow to Remove Rain X Film from Windshield

Step 1 – Clean Your Windshield/Car Window

Ensure that your windshield’s surface is clean by dusting it with a dry rag. This will remove all dust and other foreign objects that might be on the windshield. After you have dusted, use a wet rag and a mild detergent to wipe down the windshield. You can use dish washing liquid as your mild detergent.

Step 2 – Choose an Abrasive Cleanser for Scrubbing

Rain X has a silicon bonding agent in its formula. Therefore, wiping the windshield down with soap and water only will not do the job. The silicon acts as a water repellent. As such, the film will not break by using step 1 alone. You will now need to use a wet sponge and apply a course or abrasive cleanser that has some scrubbing power. Be sure to choose a cleanser that is powerful enough to scrub, but gentle enough not to leave any scratches on the windshield’s surface.

Step 3 – Test a Small Area First

Start the scrubbing process by testing a small area to the windshield’s extreme corner. Do not put the cleanser directly on the windshield. Instead, ensure that you apply the cleanser to the wet sponge as outlined in step 2. Gently scrub the spot in a circular motion. Check to make sure that there are no scratches as you go along. This is a good way to see whether or not your cleanser has the right amount of abrasion. If you see scratches, the cleanser is too harsh. If you don’t see any scratches, then you are good to go ahead. Use this cleanser for the rest of the film removal process.

Step 4 – Scrub the Entire Windshield

After you’ve completed the test and ensured that you are using the right type of cleanser for scrubbing, you can now move on to scrubbing the entire windshield. Scrub the windshield completely from one side to the other. Use your wet sponge and cleanser. You should keep the sponge very wet at all times throughout the cleansing. This is a precautionary method to avoid leaving scratches and marks on the windshield. If you are not sure how to clean car windshields and windows, take a quick look at the blog that we have on the proper way to do so.

Step 5 – Thoroughly Rinse the Windshield

When you’ve completed scrubbing the windshield, rinse it thoroughly. You can use a hose or bucket of water and your sponge. Gently wipe away the cleanser as you rinse the windshield. It is best to use cold water for the rinsing. After rinsing, dry the windshield and take a good look to see if all the Rain X film has been removed.

Here’s a video on this topic:

Tip: If any of the steps need to be repeated throughout the film removal process described in the steps above, it is OK to repeat them. Just ensure that you are not leaving any scratches along the way.

Safety starts before you drive, and that means taking precautionary steps to make sure you can see clearly on the road at all times, especially on the freeway. Rain-X is a great supplement to windshield wipers, which can leave behind streaks, reducing your visibility. Here’s a quick guide on how to apply it properly for long-term effectiveness but first, let’s learn what it is.

What is Rain-X?

Rain-X is a hydrophobic (water resistant) repellent formula designed to fill the tiny pores in your windshield, creating an ultra-smooth, water resistant surface. It works with the natural airflow of the car to help immediately disperse water, sleet, and snow from your windows.

What you need

  • One bottle of Rain-X Windshield Rain Repellant
  • Two clean cloths: preferably, one microfiber cloth, and one lint-free cloth or paper towel

How to apply it

Any contaminants on the windshield will affect how Rain-X works, so the best time to apply it is after you’ve washed and dried your car. If there is wax or any other detailing product on the windshield, remove it with a soft, abrasive cleaner. Rain-X is also most effective when applied in the shade, during fair weather temperatures, no less than 5°C (41°F).

You don’t need too much; don’t soak your rag or have it dripping down the window. A thin layer is enough. Apply Rain-X to one half of your windshield at a time with a clean cloth, preferably microfiber. Work in firm, circular motions until Rain-X is fully and evenly applied to the entire surface. Let it dry for 5-10 minutes.

Take a paper towel or a lint-free cloth and buff, moving from bottom to top. There will be a slight haze on the windshield at first. You’ll know you’re finished when the haze is gone and the windshield is bright and sparkling. If you prefer, you can repeat this step again for greater effectiveness. It’s important to make sure the haze is completely gone before you drive, to ensure maximum visibility on the road.

Finally, check and clean your wiper blades. If they are deteriorating, replace them. Whether or not you get replacements, you should clean the blades with quality glass cleaner and a cloth. This will guarantee your Rain-X lasts for a long time.

Apply Rain-X to the side and back windows for even better visibility.

When to reapply

You’ll know Rain-X is applied properly when water hits the windshield, beads up into perfect circles, and quickly runs away. If you start to see irregular shapes, or the water seems to hold better to the window, it’s a sign that Rain-X is wearing off. Time to reapply!

Using Rain-X might allow you to drive in the rain without using your wipers, but you should always have them ready, clean, and in good working condition as a precaution. And remember: in bad weather it’s just as important to see as it is to be seen, so make sure your lights work, and keep them on. Drive safely!

Rain X is one of those products that can work amazingly well if applied correctly. It can eliminate the need to use your windshield wipers almost completely and significantly improve your visibility.

Rain X is just one of many rain repellent products currently on the market. Rain X can last as long as 3 months but usually begins failing around 30 days in my experience. This is despite doing my best to apply it properly. A proper application will help improve performance and prevent streaking. But in the end, the short lifespan is its Achilles heel.

Aquapel or Gtechniq G1 are far better options in my opinion. Aquapel performs as well and lasts at least 6 months. Gtechniq G1 will last up to 2 years which is staggering.

What You’ll Need To Apply Rain X

  • A bottle of Rain X or some other brand of rain repellent. I prefer Gtechniq G1 rain repellent which lasts well over a year although it is a little more involved to apply. You need to use their G2 product to remove the excess instead of just buffing the dried G1 away.
  • Clean cloths. Preferably microfiber like those produced by the Rag Company. The other should be made of lint-free fabric or you could opt for a paper towel.

How To Apply Rain X Without Streaks (Step-by-Step)

Streaks can occur if Rain X isn’t properly applied. It isn’t a difficult job but you do want to be thorough when you apply it. If you don’t you could end up with inconsistent performance across the windshield. Here are some steps to follow to make sure you do the best job possible.

  1. Thoroughly clean your windshield before applying Rain X or any other rain repellent product. Usually, a good glass cleaner like Stoner’s Invisible Glass is more than enough to get your windshield clean. It’s a good idea to wash your car first but it isn’t necessary if you’re using a good glass cleaner.
  2. If your car is older and you have neglected properly cleaning it for some time you may need to do a deeper cleaning. If your windshield glass feels rough and more like sandpaper than windshield should feel you probably need to use a clay bar to remove the contaminants stuck to the surface of the glass. Be sure and go back over the windshield thoroughly with a glass cleaner to remove any of the clay lubricants before you try to apply any rain repellent.
  3. Avoid direct sunlight when you’re applying Rain X. Too much heat can affect the bonding process. Find a shaded area such as a garage to work in if possible.
  4. Don’t try to apply Rain X if it’s too cold out. If it’s below 40 degrees it’s too cold and you’ll need to either wait for warmer weather or find a garage with a heater.
  5. Apply a small amount of Rain X to a microfiber towel and begin wiping onto the windshield in a circular motion. I work in small areas and slowly work my way across the windshield. You should see the Rain X create a haze on the glass. Make sure you don’t miss any areas.
  6. Use a clean microfiber towel to buff away the haze left by the Rain X after 10 or 15 minutes. This will give it enough time to properly bond with the windshield.
  7. Apply a second coat to ensure consistent coverage for the best performance.
  8. It’s a good idea to replace your wiper blades at the same time. Old blades can have high and low contact spots on the windshield and prematurely wear away Rain X in spots.
  9. Also, I like to apply Rain X to all the other glass on my car. It helps improve visibility through all windows.

How Long Does It Take Rain X To Dry

It takes Rain X about 10 to 15 minutes to dry. This means that you do not need to make any serious plans about its application. Put it on, let it dry, buff it away. You are ready for rain, sleet, and snow.

How Long Does Rain X Last?

The durability of Rain X is affected by how often it rains, whether you use your windshield wipers frequently, and other weather conditions. The Rain X company states it lasts up to 3 months but most people (myself included) find that it begins failing around 30 days.

For this reason, I don’t recommend Rain X brand rain repellent. There are other higher-quality rain repellents on the market that last much longer. Aquapel for instance lasts up to 9 months but typically lasts around 6 months. Gtechniq G1 is my favorite since it can last up to 2 years. It usually doesn’t last quite that long but a year and a half is almost guaranteed. G1 is more expensive and a little more involved to apply but money and time well spent. In my opinion, Rain X isn’t worth the trouble for the short lifespan.

Does Rain X Wash Off?

If Rain X simply washed off it wouldn’t be a very good rain repellent. Any rain repellent is going to wear away over time and washing is just one of the methods that will cause it to wear away more quickly. If you need to remove it you’re going to have to do more than simply wash your car.

Steps For Removing Rain X From Your Windshield

The Rain X company recommends its product Rain X X-treme Clean to remove Rain X. Other people recommend a vinegar/water solution, glass cleaner, paint thinner, and more. Some of these don’t work well while others can be harmful to window seals, plastics, or even paint.

I recommend a 50/50 mix of Isopropyl Alcohol and water followed by a quality glass cleaner like Invisible Glass.

What you’ll need:

    • Isopropyl Alcohol or Rain X X-treme Clean
    • Microfiber Towels
    • Glass Cleaner

Step 1

Apply some 50/50 isopropyl alcohol/water mix to a microfiber towel and begin wiping it onto the windshield in firm circular motions. Avoid contact with plastics and rubber.

Step 2:

Using a fresh microfiber towel, dry the area you’ve just cleaned with the IPA mixture.

Step 3:

Once you’ve finished the entire windscreen, clean the windshield with a good glass cleaner like Stoner’s Invisible Glass.


Consider replacing your windshield wipers since they likely have some residual Rain X on them. This probably won’t be a problem but if your wipers are skipping or streaking this should be your next step.

Where To Buy

Find this Rain-X ® product at a retailer near you.

We’ve all been there. Rush hour traffic, after a long day at work. The unexpected pouring rain and the long ride back to the warm dry dwelling you call home. Whether you look through your screen or over the top this can be one of the worst scenarios you can find yourself in when on a Motorcycle. There is no windshield wiper to keep the screen clear but when using a Clearview Shield you have options that will make this, not one of the worst scenarios on a motorcycle.

The reason is the High impact plastic that we use for every replacement screen we build. This material will deflect many of the hazards the road will throw at you, while effectively staying relatively rain free when treated with the right product. The windshield has a Naturally hard surface that does not require a coating. That is the key to Clearview screen’s compatibility with products like Rain-X which sleet off rain and make general cleaning of your Windshield easier.

Products like Rain-X help you protect and Maintain your new Clearview Shield for years to come

How to use Rain-X on your Clearview Shield

When shopping for Rain-X, know that there are a few products to choose from. The thing to remember is to stick with the product in a spray or Liquid form. This will help control the amount that can be applied to your screen. Aerosol versions that recommend a direct application to the surface can create over application which produces residue and will take added steps to remove. DO NOT USE ANY OF THE RAIN-X CAR WAX PRODUCTS

Things you will need to begin

  • Rain-X windshield treatment
  • 1 soft micro fiber cloth for application
  • 1 soft micro fiber cloth for buffing or removal of excess

Step 1

Ideally you want to start with a Clean surface (See “Keeping your Clearview Clean”). For the best results apply right after removing the clear film masking from your newly purchased Clearview Shield. The 2-in-1 product can act as a cleaner but the best results will be on an uncontaminated windshield

Step 2

Apply Rain-X to your first cloth lightly saturating Fabric. 10 – 12 sprays 5-6″ from cloth

Step 3

Spread Rain-X on screens surface in a vertical or top to bottom motion, setting an even coat across the surface of the screen.

Step 4

Let dry to a light haze and buff the screen with your second dry cloth working in a horizontal or side to side motion until haze is removed

Additional tips

Only use Rain-X on your Clearview Shield. Do not use on Helmet face shields, Eye Glasses or OEM Screens

Water repellents are becoming more and more popular and many people have now begun using repellent sprays. Having good visibility in the rain is essential to maintain safety while you are driving. To ensure that your windshield remains safe and you are able to see clearly, it is important that you think about using a robust repellent.

Rain-X is one of the most popular choices, and the company has also included dedicated wiper blades that will clean your windshield.

If you don’t want to swap out your wipers, the Rain-X water treatment system is a great choice. You just have to add a bottle into the car wash bin to prevent the windows from fogging up. There’s also a washer fluid available that you can add to the washer fluid bottle to keep your car clean. Every bottle can be used to treat four gallons of water of regular washer fluid.

However, Rain-X is not the only solution. There are other alternatives available, including Aquapel, Glaco (Soft99), and Gtechniq G1. Let’s check them out one by one.

Top 3 Rain Repellents Like

1. Aquapel

Aquapel is an excellent glass treatment solution that completely changes the way drivers get out on the road in the rain. It isn’t just limited to use on the auto glass; you can also use it on other windows as well. The Aquapel is capable of fighting the elements at home, in automobiles, and in marine applications.

Aquapel was created by PPG Industries and they have created a product that focuses more on automobile safety. It repels rain and also reduces glare by a considerable margin.


The Aquapel Applicator Pack starts at $9.95. The Aquapel Glass Windshield Cleaner Can cost $4.95. The most expensive one is the Aquapel Installation Pack with the Glass Cleaner Can and it costs $13.90.


Aquapel is designed for use in four different applications: automotive, heavy-duty, marine, and household. It forms a chemical bond with the glass that increases the overall level of repellency. The water beads and then sheds from the surface and the treatment is also designed to last almost six times longer than conventional silicone-based products. It’s a great and affordable choice.


  • Affordably priced
  • Works as advertised
  • Made by professionals who know a thing or two about glass


  • Not suitable in temperatures below 50 degrees F and above 90 degrees F
  • Doesn’t improve glass durability
  • Needs reapplication

2. Glaco

Glaco is one of the leading companies that manufacture glass repellent systems and they have released an excellent coating in the form of Soft99. Designed for automotive glass, the Glaco Soft99 is a fluorine-based water repellent that mixes isopropyl alcohol and acid.

This is a roll-on that you can use on your car’s glass. It must be kept out of direct sunlight. The product must be applied to clean and dry glass using the felt applicator. Once you are done applying it, you can simply make use of a damp towel to wipe off all the residue.


The Glaco Soft99 costs $32.95 but it comes with a felt applicator and the roll-on, so you are getting pretty good value for the amount you pay. If you want something that’s reliable and will last you a long while, the Glaco gives excellent value for money.


The Glaco Soft99 will last for upwards of a year when it is applied properly. It is a highly effective rain repellent solution that you can choose for your car. Unlike most others, this one also creates a chemical bond with the glass, and this also improves the durability of the surface. It’s a pretty reliable choice for people who are interested in a decent, high-quality hydrophobic coating for the glass in their cars.


  • Lasts upwards of a year
  • Easily available
  • Increases durability


  • A bit expensive
  • Some people report a bit of blurriness for the first few days after application.

3. Gtechniq G1

The Gtechniq G1 is a clear vision glass coating that can be applied on the windshield or other glass surfaces in your car. It adds a clear, protective coating that is designed to keep the window glass clear and clean over a longer period of time. The coating is resistant to wiper blades and can last much longer than the ordinary sealants that you will find in the market.

The Gtechniq G1 also prevents smears left behind by the wiper blades and uses a special formula that keeps your windshield visibility high.


The Gtechniq G1 is sold through various distributors so there’s a difference in pricing. However, in general, the coating costs somewhere between $22.95 for the 15 milliliters and $65.95 for 100 milliliters. Most companies usually sell it for $25 and it comes with a residue remover as well.


The Gtechniq G1 is sold in a 15 mL bottle and comes with a small residue removal tool. It’s a pretty effective solution for people who want to simplify wet weather driving and need something that will improve visibility. The application process is incredibly convenient and it doesn’t take long for an average person to apply it.

Once the Gtechniq G1 has been applied, it adds a hydrophobic coating to your glass that prevents any kinds of scratches or water residue. The Gtechniq G1 can last for up to two years or up to 30,000 miles. It also makes things easier to clean bugs and other things from the surface of the windshield. The hydrophobic function greatly improves weather visibility.

I feel this is a very good product because you put it all over your windshield and it keeps the water rolling upward as you drive making a clear window to see out of while driving in even pouring rain and you dont even need your wipers!!

I used to just use regular car wax for my windows until I moved down to FL and a guy at work showed me this. It does the same thing as the car wax it just seems to last much longer. I now use rain-x exclusively for my windows. I have ran into some other off the wall brands as well and they do not last as long as rain-x.

Just apply this to your windshield and when you get to about 35 miles per hour, the rain will fly off your windshield. I had a car that had poor performing wipers and when I used rainx, it made me feel safer because I could almost drive without the wipers running,

RainX is the best, I use it on my mirrors in the bathroom and it seems to enhance your reflection. When water splashes on the mirror just a quick wipe and the mirror always shinnies with out water spots, I even use it to wipe down the inside of my shower and believe it or not the shower doors stay free of soap scum for longer. I remember driving from Atlanta to North Carolina to visit my family, of course I had cleaned my car up for my trip, and I used RainX on my windows, which always makes the view nice and clear. When I was returning from my trip that Sunday evening, about 3 or 4 hours into the ride home it started to rain, I turned on the windshield wipers and they did not work, you could hear the motor hum but the wipers seemed stuck. Now it’s Sunday night and it started to rain hard, I had to pull over and wait for it to slow down and stop so I could continue making my home. The rain slowed to a drizzle finally and I was able to continue with good visibility because the RainX treatment on my windows made it possible to see, the rain finally stopped and I got home safe. RainX works great on all glass surfaces.

**This brand has always worked for us. Whether it was going on a road trip with my father or just simply driving to work, it has never failed me yet.** **Product is easy to apply and works great. I feel safer Knowing I wont have visibility issues during a storm. I apply it to all our vehicles.**

West Palm Beach, FL

Best to apply in the shade. Use clean cloth to buff haze off window. I use Rain-X on all the windows,head lamps and exterior mirrors. I try to apply every month or so. It makes getting the large bugs off of window wih just a damp cloth, even after drying on the window in th ehot southern sun. You still need wipers in a heavy rain,but the windows dry cleaner.

Rain – X Glass TreatmentSometimes you find out about a product and you wonder how you got along without it. I don’t exactly live behind the wheel, but I’ve been driving 4 decades and put significant miles on each day commuting and joyriding on the weekends. Through all the four seasons you never think about your windshield unless you can’t see out of it; then it becomes a priority. I usually keep my car washed and waxed and the wiper blades replaced, yet sometimes the fog and rain will get the better of me and it gets difficult to keep ahead of it. That was before Rain – X.Rain – X is a liquid that you apply to a clean windshield and then buff off, just like cleaning your windshield. It dries completely invisible but it makes the glass too slippery to hold water. The little beads of water fall right off or are explosively blown off if you are driving at highway speeds. You can even drive your car with the wipers off (not recommended) and see like it’s a clear day. It works similarly in the Winter when the fog comes out and begins to mist up your windshield the wind simply blows it right off the surface and you can see perfectly. I know there are no statistics but I’ll bet Rain – X has prevented innumerable accidents. Major car washes and detailers offer Rain – X as part of their premium packages, so that should tell you it’s good stuff. Try Rain – X for yourself, and notice how much better you can see in wet conditions. Use it on your motorcycle windshield or face shield, also. This is a great product that does exactly what it claims to. :>

I love this product. Just make sure your windshield is free of dirt and then simply rub in on like you were waxing your car. When it rains or even snows (you just have to be sure your window defroster works and that the snow melts on the windsheild) and you drive away, the water bubbles up and rolls right off your windshield. Just like wipers. The only thing is that you need to be going at ;east30mph or higher to get the full effect. It’s not that expensive at all..under $5 for a good size bottle and it lasts a good long time. It isn’t good in downpours because there isn’t enough time for the water to bubble up and roll off when the rain is barreling down but other than that, it works great. I keep a bottle in my trunk just in case. You never know when a wiper blade may let you down or your wipers themselves may malfunction. It’s also good to just put on your windsheild when you neccesarily don’t need to put your wipers on. Save the wipers and let rainex bubble up the rain and roll it off your windsheild so you don’t wear and tear your wipers with that intermittent rain.

How to apply rain x automobile windshield treatment

I posted this a few months ago over on Uncommon Designs as a contributor, but in case you missed it, I thought it was a tip worth re-posting!

We recently moved into a new house, and it has a to-die-for master shower. I’m talking uber-over-the-top, need-a-diagram-to-know-which-faucet-to-turn-on kind of shower! It took some getting used to…but now I’m officially shower-spoiled 🙂 The only downside is that it’s difficult to keep clean! I’m still working on how to really get the grout clean (anybody have any great tips about that?), but I discovered a great way to help with the glass…Rain-X!

How to apply rain x automobile windshield treatment

Rain-X is a product designed to be applied to the outside of your car’s windshield – it causes water to bead and run off the windshield quickly. I figured it’d be worth a try on the shower glass to see if it helped get rid of some of those pesky water droplets left behind after every shower! Here’s what the shower door looked like after morning showers:

How to apply rain x automobile windshield treatment

It doesn’t help that we have pretty hard water at our house, so the water droplets that remain on the glass really scum up the glass quickly. See how scuzzy it looks like when it dries?

How to apply rain x automobile windshield treatment

So I decided to apply some Rain-X to see if it made a difference. After I cleaned the glass, I applied the Rain-X following the instructions on the bottle. Now, this was a brand new bottle and there were no fumes to speak of…but I know that I’ve used Rain-X in the past and it has been really stinky! Maybe it depends on the variety you get, or maybe it’s only older bottles…but regardless, make sure to turn the bathroom fan on and open a window if you need to. I used one microfiber rag to apply it, and another one to wipe the smudges clean after it had dried.

Note – The Rain-X website FAQ page does say that Rain-X is safe to use on glass shower doors. I wouldn’t let pets or children around while you’re applying it or let them lick the glass or anything, but beyond that it seems just like using any other household cleaner.

Ta-da! The water beads up and runs down the glass just like when you apply it to a car windshield! It doesn’t eliminate all of those little droplets completely, but it significantly reduces them!

How to apply rain x automobile windshield treatment

What a difference! No more scummy shower glass after just a few days…this will help keep my shower clean for much longer! I love cleaning shortcuts like that!

Do you have a favorite cleaning shortcut? Leave a comment…I am always looking for more to try out!

How to remove Rain X from outside windshield?? Solution buying a new windshield.

So I applied rain x because I had crappy blades and before I had the chance to replace them I thought I would apply rain x. It was cheaper and sounded like a good idea to me. fast forward I bought new wipers and i get streaks on the outside! looks like fog from inside but it’s from the blades, when they wipe they leave a huge fog streak! This is super annoying and I no longer want to have Rain X on my car.

I assume if you reapply it and keep re applying it, it may work but I truly am done with Rain X. I just want it of my glass but it doesn’t seem so simple.

I while washing my car paying extra attention on the windows. then I tried windex. I still have a weird look even when not using the winder wipers in rain. I get a haze at night when lights hit my windshield.

I heard people say vinager but a lot of people said it didn’t work. So my question is anyone in the same boat as me? What did you use to successfully remove rain x from the OUTSIDE of your windshield completely. I am about to buy a new windshield that is how annoyed I am about this.

P.S I know there is a thread on rain x anti fog but I didn’t want to highjack his thread so I made this one.

Up to 6 months of glass protection with one application!

Keep auto glass clear with Aquapel Glass Treatment! A single application of this patented hydrophobic glass treatment repels water for up to 6 months. Aquapel Glass Treatment bonds to the glass to dramatically improve drivers’ visibility, day and night. Aquapel is used by countless professionals to seal and protect auto glass.

Aquapel Glass Treatment is a life-saver! It’s no coincidence that more traffic accidents occur in rainy conditions. Rain coats the windshield and mixes with oils and debris to create a blurry view of the road. It can be like looking through someone else’s eyeglasses. Aquapel Glass Treatment seals the glass to repel water. Rain beads on the windshield and rolls off to maintain better visibility and safer driving conditions.

Remember, Aquapel Glass Treatment is patented. There’s no other auto glass treatment that works as well or lasts as long. Aquapel’s hydrophobic coating lasts up to 6 times longer than comparable products! That’s because Aquapel bonds to the glass, rather than just sitting on top of it. Regular glass cleaning will not affect Aquapel’s durability.

For the best results, use Aquapel Glass Windshield Cleaner, a non-streaking spray foam.

Aquapel Glass Treatment is packaged in a unique one-time-use applicator. To apply Aquapel, clean and dry the glass first. Then grasp the Aquapel applicator by the wings and place the pad against the glass. Press the wings until liquid is released. Spread Aquapel over the glass using the soft pad built in to the applicator. Go in up and down and side to side motions to get good coverage. Immediately wipe the glass dry with a soft, Cobra Microfiber Towel. If using on a large windshield, work on one half of the windshield at a time to prevent premature drying.

Once your vehicle’s windshield and glass is treated with Aquapel Glass Treatment, you can enjoy up to 6 months of clear visibility and safer driving!

Driving on a rainy day is pretty dangerous, and it would be even more dangerous at night time. It is easy to see why: rain limits vision. Think about it, when the raindrops fall on a car front glass, they make it hard to see through them. And if it is heavy rain, raindrops do pass over the window. But still, their backtrack can blur the vision through windshield. Windshield wipers can help in these cases; though, they can’t really clean and dry windows. And, sometimes, they even make things worse. That is where Rain-X comes into play. Rain-X lets the water run off the front window surface of a car. They are well popular and have made it quite easy to drive in the rain. However, some worry about the effects of these chemicals on the window surface and wonder: Is Rain-X bad for car windshield?

We will answer that question. But first, let’s see what Rain-X is and how it works.

What is Rain-X?

In simple terms, Rain-X is a mixture of chemicals that repels rain, water, and ice to help a car driver have a better vision of the road in bad weather. This treatment is a hydrophobic silicone polymer mixture, which causes water to rattle down and not stick to the car glass.

Rain-X is quite popular among drivers, especially those who are bound to drive in rainy weather. It is also suitable for use on any glass; it can be front glass, rear glass, or car mirrors.

How Does Rain-X Work?

Rain-X is a water beading technology. Think of it as an invisible wall that prevents everything from getting to your car windshield. It not only helps water pass over, but also prevents insects and dirt from attaching to the window.

What is inside Rain-X?

To answer the question “Is Rain-X bad for car windshields?” we need to see what chemicals are inside Rain-X, and see if they are destructive.

1. Ethanol

Ethanol, more generally called alcohol, is a flammable, colorless liquid that, among many other usages, is also used in alcoholic beverages like beer and wine.

Rain-X only works on clean and dry surfaces. That is why Ethanol is included in Rain-X. Ethanol removes all the dirt, dust, and oil on the windshield surface and then evaporates.

In short, Ethanol prepares the condition for Rain-X. Otherwise, Rain-X might not even stick to the windshield itself, let alone preventing other things from sticking.

2. Isopropanol

Isopropanol, also known as Isopropyl alcohol, is a colorless, flammable chemical compound with a strong odor. This compound is known for its strong disinfecting ability and is widely used in pharmaceutics, clinics, clean rooms, and electronics.

Isopropanol is toxic to humans, and that is why we have it in the Rain-X solution. Since Rain-X is an Ethanol-rich compound, some alcoholic fools may consider drinking it. But knowing that there is a poison in it, too, they would probably abandon that foolish act.

3. Polydimethylsiloxanes (PDMS)

Polydimethylsiloxane is a high-performance polymer and a member of the silicones group. PDMS is a clear and inert chemical known for its rheological properties.

The Polydimethylsiloxanes used in Rain-X form a layer on the windshield and produce low surface tension that repels fluids like raindrops and water.

4. Ethyl Sulfate

Ethyl Sulfate is a chemical compound used as an intermediate in the production of Ethanol.

During Rain-X production, sulfuric-acid is also added to the mixture. Some of this sulfuric-acid mixes with Ethanol and creates its byproducts.

5. Chlorotrimethylsilane

Chlorotrimethylsilane, also known as trimethylsilyl chloride, is a colorless volatile liquid, stable in the absence of water.

This compound is used to neutralize laboratory glass; so organics won’t stick.

6. Siloxanes and silicones, di-me, hydroxy-terminated

These are fragments of Polydimethylsiloxanes (PDMS) that can bond strongly to the windshield, making it harder for wipers to separate the Rain-X.

Can Rain-X Ruin Windshield?

No, considering the chemicals it is built of, Rain-X can’t ruin the windshield. None of the chemicals in Rain-X composition is destructive or harmful for the windshield.

What are Rain-X problems?

Generally, there are no problems regarding Rain-X. Many of the Rain-X old users have said that they never had a problem with this treatment.

However, few users report some side effects. For example, some users don’t recommend it for cars without wipers. They say it makes the visibility worse.

How to remove Rain-X from the windshield?

If you think your Rain-X treatment has begun to wear off, then it is time to remove Rain-X from the windshield, and if necessary, apply a new one.

Just remember how we said Rain-X is made of silicones. Well, these silicones are not easy to remove. So, to make your job easy, follow these steps:

  1. Wet the windshield: Use a hose or a nozzle to spray water on the windshield.
  2. Wash The Glass With Soap or Shampoo: Use soap or shampoo to create foam and use a towel to wash the windshield.
  3. Rinse The Foams: Again, use the hose or nozzle to spray water on the windshield and rinse it.
  4. Use A Windshield Glass Cleaner: There are many different glass cleaners in market. Find a quality one and use it to remove old Rain-X. The procedure is simple and classic: pour some glass cleaner on a towel and rub it against the windshield.

That’s it. Just do these and you should be able to remove the old Rain-X.


So, to conclude, the answer to our question “Is Rain-X bad for your car windshield?” is: No, it is not.

Many users have utilized this treatment for years and haven’t confronted any problem. Plus, from investigating its composing chemicals, we found no destructive chemical that can possibly ruin car windshields.

Not to forget, few users have had unpleasant experiences with this treatment. For example, some users don’t recommend it to cars that don’t have a wiper.

Also, when Rain-X gets old, it starts to wear off and obscure the vision. In these cases, you need to remove it. Since Rain-X is made of silicons, it can be a little hard to remove. So, follow the recommended steps to remove it easier.

How to apply rain x automobile windshield treatment

Rain-X is a window treatment that repels rain and is often used to treat glass windshields in automobiles. The product can also be used to treat acrylic such as wind screens in boats. Rain-X creates a product specifically designed for Plexiglass and is sold as a marine version. Applying the original Rain-X formula to acrylic will harm it to the point of decay. The alcoholic content of the original spray is not recommended in use with acrylics such as Plexiglass.

Step 1

Acquire the marine version of Rain-X. This can be done at most marine shops that offer a section devoted to detailing boats and other marine vehicles.

Step 2

Clean the acrylic surface. Use a mixture of soap and water. Clean the surface completely as the Rain-X formula will need to reach the surface and will not work properly if obstructed.

Step 3

Rinse the acrylic surface thoroughly. Dry the windshield or allow it to dry over time.

Step 4

Apply the Rain-X to the acrylic surface with a soft cloth. Apply to the entire surface area of the acrylic. Let the Rain-X dry and turn to a haze.

Remove the Rain-X completely after it has dried using a soft cloth. Gently rub the acrylic surface until there are no traces of the product. If the weather is humid, drying may take longer.

No, it did not wipe off easily. If anything, it was harder to get off than normal! Had to use glass cleaner to remove haze.

Hmm, thats crazy.. Ive never had any troubles with rain-x. Ive only used it in the liquid form once to do all the side windows. I put it on over a year ago and they still bead really well(although they are coverd in water spots.). For the windshield I buy the gallons of rain-x bugwash..

Sounds like you didn’t get the Rain-X off during the application. I like to leave it sit for 30 minutes and wipe off with a clean towel moistened with glass cleaner.

It will help remove all of the excess Rain-X and will actually leave the rainx on the glass to well, do it’s intended purpose.

Features – Rain X Windshield repair kit

The Rain-X Windshield Repair Kit is so simple to apply. It is a value for money as it can be used for multiple repairs. The kit is complete with resin repair, repair device, curing strips and razor blade, which guarantees quick and uncomplicated repair. All types of laminated windshields are repaired. It works like magic and minimizes the appearance of chips and cracks and stops them from spreading.

Applying Rain X Windshield repair

The Rain-X Windshield repair works best when the crack is fresh. Before commencing the repair, remove dust and dirt using a clean microfiber towel or other tools for cleaning your windows. Below is a step-by-step guide to repair your windshield cracks and chips using Rain X Windshield repair:

  1. Remove loose glass fragments by scraping over it with a razor blade. Affix the applicator base to the windshield. Place the center ring above the break and put the suction cups to the windshield. Do not allow the suction cups to cover any cracks extending from the central impact point. You can adjust the suction cups as the legs are quite flexible.
  2. Screw the resin chamber into the center ring until touching impact point. The device is bendable so you can re-maneuver the device until the rubber mouth is directly on top of the impact point. Check the alignment from inside the car. Screw down the resin chamber (turning clockwise) so the rubber mouth is flat against the windshield. Remember to turn it completely, but gently, so it touches the glass. Excessive pressure will alter the original curve of the glass affecting the flow of the repair resin and effectiveness of the repair.
  3. Squeeze 3-6 drops of the repair resin (drops may increase depending on the extent of the damage) into the resin chamber. Turn the resin chamber clockwise if resin leaks out of the bottom of resin chamber.
  4. Screw pressure driver into the resin chamber to drive the resin into the break. Tighten until the pressure is almost screwed all the way in. Make sure the rubber mouth has opened wide. Allow 4-6 minutes, depending on the extent of the damage. Apply heat on the windshield with a hot air gun.
  5. Unscrew and remove pressure driver from the resin chamber to release any air trapped in the chamber. Make sure there is no air bubble remaining in the break, by looking at the glass at an angle of 45 0 . For chips or bull’s eyes, examine the glass from behind the damage area. Repeat step 4 or 5 until your desired results are achieved. Make sure there is enough repair resin or add more repair resin if needed.
  6. Remove the device by turning the resin chamber and pressure driver together to counter clockwise. Wipe excess repair so it will not drip down the chamber. Add a drop of the repair resin in areas where there is still visible damage. Cover it with a curing strip for the finishing touches.
  7. When the entire application is complete, move the car to direct sunlight for about 5 to 10 minutes. Remove curing strips. Scrape clean the hardened excess resin with the razor blade.

The most successful repairs are when it is done soon after the damage occurs. Be mindful that it may not work, when the crack is over 12 inches in length and extends to the edge of the windshield. The repair also won’t work if the crack is not in the outer layer of glass.

Use RainX on a regular basis, about every 6 months I apply it. Works great. At highway speeds even with a steady downpour I don’t need to use the wipers. And the wipers make less noise, streak less, when you do use them.

I apply just like it says on the back of the bottle. Take a rag, pour some Rain-X onto the rag and apply on windows in a circular motion like wax. Once it forms a slight haze wipe off with another dry rag.

I usually let it sit on the window’s for about the same time, about 10 minutes. But only in the garage. In the sun you should wipe it off after only 5 minutes or so. It does last longer when you let it sit for 10-15 minutes, that’s why I do it too.

I’ve never had Rain-X smear. I put it on my truck after 120K miles for the first time, and became a true believer. My only complaint is that it doesn’t last very long (approx 2 months).

How long are other people’s lasting? Have you tried their Rain-X glass cleaner? It’s suppose to make your Rain-X last longer.

THe reason your rain-X applications may only be lasting 2 months is because you are putting on a very thin layer. YOu might want to try to apply a thicker layer or apply 2 or 3 layers of rain-X, one after another, every time you apply rain-X..

My windshield wiper moter broke, and because of rain-x I didn’t bother to fix it for over a year. (Intermitant peoblem, when I got the truck the wipers didn’t work in winter, eventially they went out in summer. I didn’t care, with rain-x I never used them anyway.

Then I got a job in the city, where I had to deal with stop and go traffic. Rain-x is worthless at less then 20 mph, and of questionable worth at less then 45. For the times when it rains and traffic is not bad I like it.

Just remember that even though you can see better with rain-x in heavy rain then wipers, doesn’t mean your can’t hydroplane. Keep the speeds reasonable for the condidtions.

i’ve been using rain-s for several years and i’ve been applying it straight to the windshield and using paper towels to smooth it around and buff. i don’t think that this has any deleterious effect on the product – however, I never wait to take it off and it still lasts me about 2 months on the windshield. for the above post who said it doesn’t streak, how do you apply it? the worst is driving in the city with streaking and lots of lights. i’d like to correct that if possible. thanks.

I tried Rain-x for a year and ended up hating the stuff because of the extreme streaking in city traffic. I stopped using it all together.

Instead, a friend who drove a Seattle Transit System bus told me that they use ordinary “Cream of Tartar” on their windshields, it’s an ordinary kitchen spice – I believe.

I place the powdery stuff in a shallow soup bowl, add tap water to make a paste and apply to the windshield with a wet sponge in a vigorous circle pattern. Then, rinse off with a garden hose or, with a clear wet sponge until the glass is clear. I mean to tell you that the paste cleans every molecule off of the windshield – almost like a miracle. If you want to really clean a windshield – try it once or twice to see the results.

The cream of tarter paste consistency is about the same as a pancake batter mix – maybe a little more body.

Are the hot dogs beef, pork, pork and beef, deer sausage or Italian sausage?

With your comment, I take it that you think the process with cream of tarter is a farce?? I say to you — try it -you’ll like it.

Just like with your paint, water spots, tar or rubber, and other road grime will aggressively build up and stick to your windscreen.

Claying your windshield is the best way to remove buildup of contaminates on glass.

The clay will pull out all sorts of stubborn debris that will cause your glass to feel rough and look dirty even after a thorough wash with even the best glass cleaner.

The process to clay glass is essentially the same as paint. You’ll need to thoroughly wash and clean your glass first.

Clay Bar Windshield Water Spots

  1. Thoroughly wash all glass that you intend to clay
  2. Apply clay lubricant to a 2 foot sq. area
  3. Glide the clay bar across the area until the water spots and contaminants are removed
  4. Thoroughly wipe the area with a microfiber towel
  5. Repeat in 2 foot sq. sections until complete

Then you’ll need to apply a lubricant to the glass and run a small piece of clay bar over the windshield or windows.

After cleaning a section of glass with clay use a microfiber cloth to thoroughly remove the clay lubricant.

You may want to use a good glass cleaner one last time if the lubricant leaves any haze or streaking.

Once done your glass should feel silky smooth and look crystal clear. It’s the ultimate way to ensure that your windshield is absolutely pristine.

Steps for claying glass

  • Thoroughly wash your car or truck to remove as much road grime as possible.
  • Apply clay bar lubricant to an approximately 2 foot square area. This is to ensure the lubricant won’t evaporate before you get a chance to clay bar the entire area.
  • Use a small piece of clay bar to rub back and forth across the area until it glides smoothly without grabbing in any points of the 2 foot area.
  • Thoroughly wipe the 2 foot area that was just clay barred with a microfiber towel to remove the lubricant.
  • Check the clay bar for build up of debris and fold over hide the contaminants within the clay and create a clean surface on the clay to continue cleaning. Not inspecting the clay and folding it can cause the debris to buildup and scratch the paint.
  • Repeat the process in 2 foot square areas until the windshield is completely cleaned.

What’s the best lubricant for clay barring glass?

When clay barring any surface you need to have a lubricant to allow the clay bar to glide over the surface.

There are various liquids that can be used. Don’t make the mistake of using glass cleaner or similar products though.

They can break down the clay bar and just cause it to smear across the glass.

The best lubricant we can recommend is Chemical Guys Clay Luber.

It’s a great choice since it shouldn’t streak and will wipe clean with a microfiber towel.

What’s the best windshield clay kit?

You don’t need a special clay or lubricant for glass. Regular paint clay and lubricant will work just as well on glass as it will on paint.

The only thing you may want to keep in mind is the lubricant. Using a lubricant that will wipe away easily without leaving a residue or streaking.

We like the Chemical Guys Clay Luber but you simply use warm water if you prefer. We recommend the Chemical Guys Clay Kit since it includes their lubricant.

Will a clay bar remove scratches from glass?

Unfortunately no. All a clay bar will do is remove road grime that is stuck to the glass that simply washing won’t remove.

You’ll want to use care when clay barring your windshield to ensure you don’t create scratches though.

Inspect the clay regularly and fold when contaminants build up on the surface of the clay.

Folding the clay will give you a clean surface on the clay itself. If the clay gets too much contamination buildup you may want to get a new piece of clay.

If you inadvertently pick up sand grains or other hard bits in the clay you can accidentally scratch the glass if you’re not careful.

If you drop the clay on the ground the safest thing to do is use a fresh piece of clay.

Will a clay bar remove windshield water spots?

A clay bar should be able to remove any surface buildup from glass including hard water spots.

Clay bars will remove most contaminates that sit on the surface of the glass.

You may need to apply a little extra pressure to remove more stubborn things stuck to the glass.

Just be sure the clay is particularly clean when applying extra pressure to ensure that you won’t accidentally scratch the glass.

Can you clay bar the inside of a windshield?

While you can clay bar the inside of a windshield there really isn’t much need to do so.

It would also be very difficult to do without making a significant mess since you’d need to lubricate the surface of the glass.

Clay barring the exterior of the glass makes sense because road grime will stick to the surface over time.

The inside of the windscreen isn’t usually exposed to contaminants that will stick to the glass that couldn’t be removed with typical glass cleaners.

A great glass cleaner that works extremely well without streaking is Stoner’s Invisible Glass.

They offer a great Reach & Clean Kit that is ideal for cleaning windscreens and reaching into the difficult to clean areas near the dashboard.

Claying your windshield will leave it silky smooth and much cleaner if you’ve had your car for some time and have never clayed the windscreen.

Road grime builds up over time and some adheres so strongly to the glass that washing simply won’t remove it.

The only way to truly get it to come off is with a clay bar. Be sure to wash the surface before attempting to clay bar or you’ll be far more likely to end up creating scratches.

Use a proper clay bar lubricant so the clay bar will glide across the surface.

Work in small areas and wipe away the lubricant as you go.

Be sure that your clay bar is clean and fold it regularly to freshen the surface of the clay you’re using.

Once you’ve finished claying the entire windshield it should be very smooth to the touch and no longer rough feeling.

It should also be much clearer than before.

How to apply rain x automobile windshield treatment

Windshields are hard to repair, regardless of the problem. It takes patience and planning, a thorough understanding of the process involved and a realistic expectation of the outcome. Improvements can be definitely made, but returning damaged glass to like-new quality is highly unlikely. With that in mind, there are several processes that can be used to polish pitted glass. Severely abraded glass should be replaced.

Step 1

Scrub the windshield with a nylon-bristle brush. Use a liquid dish soap. This will strip any oily residue from the glass and clean the pitted areas of any particles that have been trapped inside them. Rinse the glass with water.

Step 2

Put on the safety glasses and gloves. Apply a commercial polishing compound to the glass and polish it using a variable speed drill set on low. Most compounds contain cerium oxide as an abrasive. This removes glass until the surrounding area is level with the pit. As the glass is being removed, some of it will begin to fill the pit and give a false impression that the pit is being repaired. To prevent this, continually flush the area by lightly squeezing a sponge that has been soaked with water to keep the compound damp.

Step 3

Scrub the area with a brush and liquid dish soap again to remove the used compound and clean the pitted areas. Dry and inspect the polished area. Apply more compound and polish the area with the drill. Keep the area damp. Do not let the compound become dry, as that could cause unwanted scratches. Continually moisten the area with a small trickle of water from the sponge. Repeat this process until satisfactory results are achieved.

Clean the glass a final time and apply a rain-repellent formula available at auto parts stores. These fill in small surface imperfections, improve the overall appearance and add enhanced viability. They have the added benefit of repelling water and slowing windshield abrasion.

  • When i took delivery from dealership I told them not to do a pre-delivery valet as I wanted to do it all myself and avoid swirls from careless work.

    But. I have two probs

    1. I can`t seem to get windscreen clean. After cleaning inside and out of windshield with regular auto glass cleaner, I still had a sort of rain drop/dribble/grubby pattern visible and couldn`t work out what surface it was on, interior or exterior. Maybe both?. So, used autoglym glass polish, and that seemed to do the trick. But today, it rained and winshield stemed up inside revealing the same pattern of grubbiness. Again, I cant suss out if its inside or outside as both feel smooth to the touch. Any ideas, tipe etc etc. Maybe I just need to polish the windshield 2 or 3 times? :nixweiss

    2. Having applied rainex, I`m now getting bad wiper judder. Why? I applied this from new on my last TT which was exactly the same 2003 model (first car replaced as it was a lemon) and never had any probs whatsoever. Any ideas?

    Thanks for all your on-going assistance. Thanks to adice I got here the paintwork is beautifully finished, and this is really bugging me.

    One last question, I bought rainex anti-fog for interior if windows as TTs are prone to missty windows. Is this stuff any good? . Doesn`t that leave streaks? Any application tips?

    Remember put the Rain-X on the cloth and make sure it does not get on the paint. The old formula is/was not paint safe. Don’t know if the newer Rain-X products are paint safe. Make sure you read the labels.

    As far as how well it works, does what it’s suppose to do, helps to keep the windshield clearer when it’s raining. I have found that as long as the windshield is cleaned before using Rain-X, the wiper blades should work smoothly during a light misting type rain, and not skip or make any noises when working, unless their worn or coming apart.

    I only notice the windshield haze either during the morning commute. when the sun is streaming in and the dirty, hazy windshield is making it hard to see.

    Or, when it is raining out in the winter and the salt has caked up on the windshield, creating a haze.

    Unfortunately, parking and waiting for the rain to pass isn’t an option because I’m always running against the clock. S

    The last thing you want while driving is for something to obstruct your view of the road. And that’s what makes windshield haze a foe. Haze buildup is a common occurrence.

    Thankfully, it doesn’t take a genius to get rid of it. Here’s a quick guide on how to keep your windshield crystal-clear.

    What Causes Windshield Haze

    Interior Windshield haze is a thin film buildup made up of airborne contaminants from interior materials, pollutants, gassing, and cleaning products. Let’s have a closer look at some of the common causes of hazy windshields.

    Exterior haze is generally from salt, road grime, pollen or pollution.

    Cleaning Windshield Haze

    1. Lay Bath Towels on your Dash To Protect It
    2. Fill A Bucket with Dish Soap and Water
    3. Use a Terry cloth rag to clean the windshield with the dish soap mixture. Use a circular motion.
    4. Use a Squeegee to remove the liquid from the windshield for streak-free visibility.
    5. Apply Rain-x To the inside of the windshield as a preventative.

    What Causes Windshield Haze?


    The humidity in the air can cause a little moisture to form on the inside of your windshield. This attracts dirt that then clings.

    As the day heats up and the humidity evaporates, that residue remains.

    This repeats daily, causing a build-up on the cleanest windshields and creating a haze.

    Smoke residue

    Cigarette smoke leaves a yellowish residue on the inside of the windshield. If you smoke regularly in your car, you’ll begin to notice a buildup of smoke residue in the sides of your windshield. It’s safer for you and others to smoke outside of your car.

    Offgas from vinyl or plastic

    As direct sunlight heats your car, the vinyl and other plastics begin to break down and evaporate onto the windshield. It often happens during the summer, and new cars are more susceptible to off-gas from vinyl or plastic.

    Water & Mildew From The Floor

    Moisture inside your vehicle can cause a haze to form on the inside of the windshield. Maybe you have an open bottle of water, or there’s mildew in the fabrics of parts of your car that never dried out. You need to get rid of all of those.

    Engine or heater coolant leak

    An engine or heater coolant leak can enter your vehicle through the front vents and form a green haze on your interior windshield. It has a strong smell and is not hard to miss.

    Hard water, acid rain, dirt, & salt on the outside

    An exterior windshield haze isn’t any different from an interior one. It may be caused by acid rain, hard water, dirt, pollen, or sea salt. If you live near the sea, you’re going to have this salt problem often.

    7 Products to Remove Interior Windshield Haze from your windshield

    Below are DIY mixes and branded products you can use to remove windshield haze. You may also contact your car manufacturer to be on the safe side.

    1. Rain-x

    Initially created for aviation windshields, Rain-x has become a go-to product for cleaning car windshields and wipers. You can add Rain-x Glass Treatment to your regular car wash tools and apply using a microfiber towel and a spray bottle. To get rid of ice on your car windows or windshield, you can use the Rain-x De-Icer washer fluid. These windshield cleaners and fog repellants also prevent interior windshield haze.

    2. White vinegar and water

    If you can’t afford branded products, then try this white vinegar and water DIY solution. It’s a cheap, accessible, and efficient remedy. Simply mix white vinegar and water. The recommended mix ratio should be 10% vinegar 90% water. However, you can increase the vinegar percentage, depending on the severity of your car’s windshield haze.

    3. Ammonia-free Glass Cleaner Spray

    If you can afford a branded ammonia-free glass cleaner, then you can try out Windex or Rain-x 2-in-1. Ammonia-free glass cleaners leave no residue when cleaning. Alternatively, you can make some ammonia-free glass cleaner at some. You’ll need rubbing alcohol, distilled water, white vinegar, peppermint essential oil, a glass spray bottle, and a funnel.

    4. Cleaning Clay

    Some particles bond to the glass and are more challenging to remove than other substances. These particles could be road tar, water spots, grime, grease, road films, or oil. Cleaning clay efficient removes stubborn gunk from your car windows and windshield.

    5. Invisible Glass or Glass Cleaner Aerosol Product

    If you’re tired of glass cleaners that leave visible streaks on your windshield, then try some invisible glass aerosol products. Invisible glass cleaners don’t contain any dyes, surfactants, or soaps, which may leave some residue behind.

    6. Mr. Clean Magic Eraser

    Mr. Clean Magic Eraser is a trusted cleaning tool for your glass window and windshield. It acts as safe sandpaper for removing stubborn grime buildup from auto glass, leaving your glass clear of any debris.

    7. Rubbing alcohol

    Rubbing (isopropyl) alcohol disinfects your car surfaces and leaves them streak-free when the job’s done. What’s more, isopropyl alcohol is safe to use on your car’s windshield and doesn’t affect your tint. All you need to make the rubbing alcohol solution is to mix two-thirds of isopropyl alcohol with one-third of distilled water.

    Tips For Cleaning your Windshield

    • The entire cleaning process can be condensed into two simple steps. First, spray your removal product on the windshield. Second, wipe! But, while you’re at it, there are few things to keep in mind.
    • Wipe the glass with a squeegee or microfiber cloth. That needed to be said because sometimes you’ll be tempted to towels use paper towels instead. Paper towels, however, leave lint and residue behind and could cause streaking. See how that defeats the point?
    • To remove grease, use your rubbing alcohol and another microfiber towel. And if you’re dealing with haze caused by sea salt, use vinegar. And makes sure not to use Ammonia on tinted windows
    • Most glass or window cleaners will hurt your dashboard if they drop on it. So don’t forget to cover your dashboard with towels when cleaning.
    • If one side of your towel gets dirty, turn to the other side or pick a new towel altogether. Don’t be lazy.
    • Clean your windshield in a shaded area to avoid quick evaporation of glass cleaner fluid.

    Should You Use WD 40 on Your Windshield

    Yes. WD 40 is an excellent solvent for the safe removal of almost any substance from your windshield. Removable substances include tape, adhesives, and stickers.

    Before the rainy season officially begins, it’s better to take a second look at your vehicle and ask yourself: Is my car ready for wet weather driving? Here are some helpful tips on how to prepare your car for the rainy months ahead.

    Rainy Season Vehicle Checklist

    Do you want to drive confidently in the rain? Check the following items before the monsoon season starts.

    Step 1: Inspect the lights.

    Park your car, engage the handbrake, and turn on all the lights, including the daytime running lights (DRLs), headlights, foglights, turn signals, hazard flashers, and taillights. Make sure that all the lights are working. If you find a broken or busted bulb, replace it immediately.

    How to apply rain x automobile windshield treatment

    When driving in rainy weather or heavy downpours, road visibility is the number one factor in preventing accidents. Also, driving a car with busted taillights or headlights is illegal and will merit a violation ticket from your friendly traffic enforcer.

    Step 2: Check the tires.

    The tires in your vehicle are responsible for keeping you on the road. Balding or worn-out tires will not offer much traction and grip when driving in the rain. Unbeknownst to many, the tires play a significant factor when braking to a stop. Even if your brakes are good, the vehicle won’t stop readily if your tires are bald.

    How to apply rain x automobile windshield treatment

    You can avoid accidents when the roads are slippery by replacing or rotating the tires before the rainy season starts. We know that new tires don’t come cheap, but you can’t put a price on your and your family’s safety.

    Tip: If your tires are relatively new, make sure to check the tire pressure regularly. If you do not know the ideal tire pressure, read the owner’s manual or check the placard on the driver’s side pillar. In most cases, maintaining a tire pressure of 30 to 32 PSI is ideal for vehicles equipped with 15-inch to 17-inch tires.

    Step 3: Inspect the windshield wipers.

    When driving in a sudden, heavy downpour, the windshield wipers are your best friend. Old wipers are not as efficient in clearing the windshield of excess water and moisture as new wiper blades. It’s a good idea to replace the wiper rubber or wiper blades at least once or twice a year, preferably after the summer months end and before the rainy season begins.

    How to apply rain x automobile windshield treatment

    You can learn more about how to care for, restore, and replace the wiper blades in your vehicle by clicking here.

    Tip: You can apply Rain-X or any other windshield treatment to improve visibility further when driving in the rain.

    Step 4: Check or replace the battery.

    The best time to replace your car’s battery is before the rainy season begins. Dealing with a weak or faulty battery is a huge hassle, and it’s doubly more so if your car breaks down in the rain. If you have a multimeter, you can check if the car battery is maintaining a 12-volt charge.

    But if you don’t know how to use a meter, you can bring your car to a battery shop and have the battery checked there. Better still, you can replace the battery and save money by following our tips here.

    Step 5: Inspect, replace, or refill all vehicle fluids.

    Yes, we mean the engine oil, coolant level, washer fluid, brake fluid, and automatic transmission fluid (ATF) or clutch fluid. Again, it all has something to do with preventing breakdowns and keeping your car running when driving in inclement weather.

    How to apply rain x automobile windshield treatment

    Engine Oil – Open the hood and pull out the engine oil dipstick. Wipe the end of the stick with a clean cloth and insert the dipstick all the way to get an accurate oil reading. If the oil level is low, you can either refill or change the oil altogether.

    Coolant Level – Inspect the coolant reservoir and refill if necessary. NEVER open the radiator cap when the engine is hot.

    How to apply rain x automobile windshield treatment

    Washer Fluid – Refill the windshield washer reservoir with clean water or any type of washer fluid.

    Tip: Remember to inspect all vehicle fluids every time you fill the car with fuel.


    It does not matter if you have a new, used, or repossessed car. It’s a brilliant idea to double-check the lights, tires, windshield wipers, car battery, and all vehicle fluids before the rainy season begins.

    How to apply rain x automobile windshield treatment

    Here are a few frequently asked questions about this amazing product and why it’s a great feature to use for your next car wash.

    1. How Long Does RainGuard Last?

    The first question is probably the most difficult to answer because it depends on a number of factors, primarily weather. RainGuard helps to repel water and other particulates from your vehicle while at the same time increasing visibility. Excessive rain or snow will decrease the effective time of the application.

    As a general rule, when applied in a car wash setting, RainGuard may be effective for up to two weeks before you start to see less “beading” on the windshield and body. Repeated applications during this time will enhance and extend the effectiveness of the application.

    2. What Is RainGuard Made Of?

    RainGuard is comprised of a hydrophobic silicon polymer. The “hydrophobic” part is what causes the noticeable RainGuard “beading” of water on the windshield.

    3. Does RainGuard Repel Dirt or Dust?

    RainGuard is not designed to repel dirt or dust. However, in practical use, it has been shown to deter some of these elements. Most likely this is due to the hydrophobic nature of the product. If there is moisture in the dirt it may provide some level of effectiveness.

    4. Is RainGuard A Wax?

    In practice, RainGuard may behave similarly to a wax. In fact, some skiing and snowboarding enthusiasts have been known to apply RainGuard to their boards and skis to help navigate sticky, wet snow environments. However, RainGuard is not technically a “wax.”

    5. Does RainGuard Really Help Improve Visibility?

    RainGuard was shown to enhance visibility and improve response time by as much as a full second or more. At highway speeds, this may translate to as many as four car lengths worth of extra stopping distance.

    When To Use?

    RainGuard may be used whenever you wash your vehicle. An application of at least 1x per week will help replenish the coverage and keep your vehicle treated. For maximum protection, use RainGuard whenever you wash.

    RainGuard is available on all Xtreme level washes at Xtreme Clean or as part of our Signature Wash Upgrade.

    Best way to apply Rain-X?

    2009-Jun-27 12:58 pm

    Use a decent glass cleaner; I use Invisible Glass, to first clean the surface. Let it dry.

    To apply rainx, I use a single cloth or sponge. Soak it fairly good and apply to the window surface liberally. When a haze forms, apply another fresh coat. When that drys to a haze, use a clean, dry terry-cloth or similar material to remove the haze. It’s like waxing a vehicle. It takes some time and elbow grease.

    First I’ve ever heard of this product. Sounds/looks like it works well, though it is pricey.

    I’ve tried Rain-X on my windshield and I don’t like the way the wipers are affected by it. So I only ever use it on my side and rear windows. For those, it’s probably been a few years since I even bothered with them.

    The video certainly does show that the aquapel stands up a lot longer than RainX.

    2009-Jun-27 6:06 pm

    NEVER, EVER try this on a motorcycle visor.

    it will ruin it, in short time.

    2009-Jun-27 6:11 pm

    I like the way this man thinks.

    2009-Jun-27 6:55 pm

    I found the rain-X OK on the windshield until it started to wear off. The streaking was so bad I could hardly see at night. It was either reapply the stuff or let it wear off completely. I chose to let it wear off.

    I’ll never put the stuff on a windshield again but side or rear windows or mirrors are OK.

    2009-Jun-27 7:07 pm

    2009-Jun-27 7:12 pm

    Prestone makes a repellent for use in the windshield washer fluid. I like it better than the Rain-X brand. Couple bucks more for either brand over the typical blue washer fluid. Worth it in my opinion. But both do leave a momentary haze when you hit the wipers. Not good at night driving tight neighborhood streets.
    I see Aquapel has it also for washer fluid.

    I have noticed the slight streaky grease look when using any wax/rainX & the wipers. I have never noticed this when its raining, only when I try and use my washer fluid to clean the windshield.

    Using the wipers is pointless with rainX, if I go anywhere over 50mph, all the rain just blows right off & I can see much better than using the wipers. This works in anything except a downpour, which wipers don’t help much either.

    2009-Jun-27 9:44 pm

    I just wax my windows with Nu-Finish (or similar), and use liquid silicone on the wiper blades and I’m good to go for cheap.

    Applying Rain X treatment to your windshield and windows can help them shed water. Rain X makes it much easier to see out of your windows by repelling other elements such as dirt and road debris. However, you may have heard that Rain X treatments can cause your windows to film up and haze, thereby causing a driving hazard.

    How to Remove Rain X

    Rain X can be removed as easily as it is applied. To remove Rain X, use a cleaning agent such as rubbing alcohol, vinegar, or dishwasher soap. Spray a healthy amount of any degreaser onto a microfiber cloth. Simply rub the degreaser in a circular motion on your vehicle’s glass until it’s clean, switching out microfiber cloths if/when necessary. The glass should be clear when all the Rain X is gone.

    What Solutions Get Rain X Off Your Windows

    When it’s time to remove Rain X from your windshield, turn to the following solutions. Each of these can also be used on your wiper blades and windshield to clean them, even when a window treatment isn’t applied.

    Rubbing Alcohol (IPA)

    Isopropyl alcohol, also known as rubbing alcohol, can be used for a variety of automotive applications. For instance, it’s often used to remove wax from your vehicle, and can be a great prepping tool before you begin buffing. The best part about rubbing alcohol is that it evaporates quickly and leaves little residue.

    We recommend using an IPA dilution ratio of about 10%. It’s the most effective and safest ratio, even for the toughest contaminants. Rain X should come off easily with a 10% IPA solution.


    Windex isn’t just for cleaning glass around your home. You can also use it to clean your automotive glass. Windshields and windows alike will gleam like new with a little Windex, a microfiber cloth, and a smidgeon of elbow grease.

    Windex can be diluted or used straight, depending on your preference. As you clean your glass with Windex, you can also wipe down rubber mouldings, plastic surrounding trim, and your wiper blades. Dirty wipers oftentimes contribute to a streaky windshield, so keeping your wipers clean can lengthen the life of a clean windshield.

    Glass Cleaner

    Most glass cleaners are sold in an aerosol can, which makes application quick and easy. Foaming glass cleaners work best for windshields that see a lot of contaminants. The foaming action allows the product to lift away dirt and debris without scratching the glass beneath. Glass cleaners can typically be used on tinted glass as well, without causing any damage.

    Car Wash

    Removing Rain X doesn’t have to be a chore. You can also drive to the nearest car wash, whether it’s self-serve, drive-thru, and/or touchless. The degreasing agents and soaps should go a long way in breaking down any Rain X still left on your vehicle.

    Just remember that if you applied Rain X to your interior windows, a car wash won’t be able to help you there. Unless, of course, you like to live on the wild side.

    How to apply rain x automobile windshield treatment

    How to Remove Rain X

    Removing Rain X can seem like a monumental task. Windshields aren’t cheap, and who wants to clean their car windows for hours on end? Trust us, there’s an easier way.

    If you’re looking for a way to remove Rain X, follow our step-by-step guide below. But first, let’s assemble the necessary ingredients.

    Gather Your Supplies

    Before you can remove the Rain X on your windshield and windows, gather the following supplies:

    • Several dry microfiber cloths
    • Rain X removal solution
    • Spray bottle
    • Car keys
    • Your vehicle

    It’s easiest to remove Rain X if your car is parked inside a garage or underneath an awning. Sunlight will evaporate any chemicals you use at a faster rate in higher temperatures compared to a cool, covered environment. Good lighting will help you to see if you’ve removed all the product as well.

    How to Remove Rain X From Your Windows

    Once your supplies are gathered, follow the guidelines below to remove Rain X from your vehicle’s windows.

    1. Step 1: Dilute your Rain X removal solution of choice in a spray bottle, if necessary, and spray it onto a dry microfiber cloth that’s folded in fourths. While you want enough solution on there to dampen the cloth, too much will make more work for you than necessary.
    2. Step 2: Working in a circular motion, wipe the solution across the glass. You may find it helpful to break the windshield into two sections (driver and passenger sides).
    3. Step 3: Once the glass is covered, take a dry microfiber cloth folded in fourths and dry your windshield. You can use a circular motion, or a cross-hatch pattern if you like.
    4. Step 4: Continue this routine around the vehicle, working (a) on exterior surfaces and then interior surfaces, (b) vice versa, or (c) a single window (inside and out) at a time.

    Removing Rain X from your vehicle shouldn’t be a hassle, if you’re using the right products.

    hey, i hope this isn’t redundant or been discussed elsewhere. i did some searching and reading and didn’t find quite what i was looking for.

    so, dating myself, i used RainX way back when it was pretty new in the early 1990’s. my experience then was that it worked really well at highway speeds where i pretty much didn’t even need to use my wipers at all.

    the downside, however, was when i was traveling at low speeds. not only would the water beads not “sheet away,” but i found my wiper blades didn’t work very well because perhaps the windshield was so smooth that they couldn’t squeegy away the water.

    has the formulation changed? what are people’s experience with Rain X for around town driving? do their wipers work “normally”?

    ^ I dont think he is referring to wiper blades themselves.

    From my understaning and limited research, rainX window solution works, but for only limted amount of time before it wears away. I’ve heard better reviews of this product Kit_p_545.html

    I believe its stated on the bottle that its 40mph and up efficient. I use it all the time, and its very dependent on how clean the windshield is before application and how often you use the window sprayers and what solution you spray as well.
    From my experience the best application is to put it on an hour or so before a good rain storm is coming and not wipe the haze that appears when its dry. let the rain clean the haze, weather its driving or sitting over night. I usually clean my windshield with denatured Alcohol once a year to get it 100% clean to the base and then apply the Rain-x. its sticks around the longest after that. I have also found that if your using a de-ice windshield fluid it will burn off the Rain-x pretty fast unless its their brand fluid. Also if you put Ammonia in your windshield fluid the Rain-x is toast.

    Old wipers will take the Rain-x off particularly fast too. I replace my blades like 3-4 times a year. A good money saving tip on that is to buy the new good non-metal wiper blades and then when the rubber is shot get the cheap old school blades and swap out the rubber edges. It takes like 10-15 min and will save you like $35

    rain-x was ‘new’ in the early ’80’s. not the early ’90’s I think it hit the market, originally, in the mid ’70’s, actually
    I still have a bottle from that era in the bottom of my toolbox

    and yeah. it works fine if the blades are new-ish and at lower than 40mph

    i have used it and loved it and used it and hate it

    i dont use it any more. more hated it than loved it

    I would be inclined to give the aquapel a shot to see if it works more/better/something than the rain-x

    I use it on everything (or a version of it), works great for racecars that may otherwise not have wipers at all, or using wipers would be distracting. Keep your blades fresh and re-treat annually, no problems.

    We had a loaner car for a few weeks that did not have any rain treatment, got caught in two pretty substantial downpours, and were nearly incapacitated. had to pull over. Never had to do that with a treated windshield.
