Will Rain-X Damage My Windshield?

No, it won’t!

There are plenty of glass treatment products out there that claim to improve visibility only for you to find out they are unfit for your windshield.

Well, Rain-X doesn’t belong to that category. This is a product that has been around for years. And if you read through its reviews, you will be surprised at the numerous positive feedback it gets on the regular.

Its water repelling benefits make it a reliable glass treatment that can be very useful to motorists who drive in areas that experience lots of rainfall and snow.

The only drawback that may be related to Rain-X damaging your car’s windshield is the residue that it leaves behind when the treatment starts to wear out.

This residue will make your wipers squeak as they wipe off the windshield. The squeaking is annoying and if not corrected, it will cause wear on the surface of the windshield.

Obviously, as a smart motorist who is aware of his/her vehicle’s performance, even before the Rain-X treatment wears off and causes squeaking of wipers, you should reapply or remove it off your windshield.

Later on, I will share with you some of the most effective ways on how to remove Rain-X from your windshield.

The other disadvantage of using Rain-X is that if the treatment is exposed to lots of dust, and the windshield isn’t washed regularly, streaks and tiny droplets may form on your windshield.

A thorough cleaning can get rid of this and ensure Rain-X continues to serve its purpose.

As you can see above, Rain-X is safe to use on your windshield and it delivers impressive results. To learn more about Rain-X and whether it’s harmful to your windshield, keep on reading this review.

This is a silicone-based water repellent windshield treatment that is very effective and fairly easy to apply. It’s the perfect product for car owners that are looking to improve visibility during rain or snow weather. Other than repelling water droplets, Rain-X also wards off dirt and bugs.

Rain-X isn’t only popular because of its effectiveness at repelling water but its ease of application. You don’t have to be an expert for you to know how to apply this product to your windshield.

It comes with a manual and please note that Rain-X shouldn’t be applied on the inside of your windshield. Because you won’t be able to see a thing when moisture builds up in your car interior.

Being a silicone-based windshield coat, Rain-X has to be applied regularly. The frequency of application will depend on the weather conditions of your area of residence.

You will know that your treatment has worn out when you start hearing the squeaking of wipers. Alternatively, if you aren’t so pleased with Rain-X it can be removed easily.

Knowing how it works is crucial in determining if it’s safe to use on your windshield. You will be glad to know that Rain-X uses water beading technology.

In that, it creates an invisible barrier between your windscreen and the environment. It does not in any way penetrate the windshield or eat through the glass.

The water beading technology ensures water doesn’t get into contact with the windscreen. And thanks to the natural airflow experienced when one is driving, water slides off easily and the driver can enjoy improved visibility.

That aside, the same technology is also responsible for repelling hard water and bug stains.

Rain-X can be bad for your windshield if not applied correctly. As you may already know, Rain-X is a foreign element that is being introduced to your windscreen.

And if not applied correctly, it may not damage the windscreen directly, but it can cause streaking and affect your visibility and safety on the road.

Applying Rain-X is a fairly easy process that can be done by anyone, no matter your level of experience in such matters.

The product comes with a guide, but for the sake of increasing your general knowledge, here is a step-by-step guide.

  • Before applying, clean and dry your windscreen. If it’s dirty, the product won’t coat evenly on your screen.

 

  • Once it’s dry, use a wet microfiber cloth to apply the product to the glass. Start from the top going down. Your objective should be to create a very thin coat, so don’t be too generous with the Rain-X.

 

  • Wipe off any excess Rain-X and let it dry.

 

  • With the help of a paper towel, buff it till it clears up.

 

  • Clean the wipers and give your car a test drive.

The application of Rain-X should be done on a day that is cool and dry.

Is It Advisable to Use Rain-X on Glass?

Because the windshield is made of glass, it is normal for you to question if Rain-X can be used on such surfaces. According to the manufacturer, Rain-X can be used on all types of glass.

This includes those on cars, at home, and commercial properties. It’s a glass treatment product and if you are okay with it, you can use it on your windows.

Is Rain-X Bad for Your Wipers?

The wipers are the windshield’s best friend. So, whatever you use on the windshield will affect the wipers and vice versa.

If you were having some doubts about the safety of Rain-X on your windshield, you may also have had some fears about it damaging your wipers.

Here is what you need to know: Rain-X will prolong the life of your wipers by making their job of wiping rain droplets easy.

However, if you fail to re-treat or remove Rain-X once it has served its purpose, the residue left behind will clatter your wipers. And you may have to replace them right away.

With the wipers, using Rain-X is a win-lose scenario. It acts as a helper when it has been applied, but the day it wears out, it turns into a ‘foe’. It’s up to you as the car owner to know how to deal with the two.

How to Remove Rain-X from Your Windshield?

It’s not everyone who will be pleased with Rain-X. You may have applied it wrongly and the streaking could be getting on your nerves every time you step into your car.

Or, after applying it, you may have heard a terrible experience such as your wipers clattering on the windscreen. Even though Rain-X isn’t bad for your windshield, you may have your reasons for removing it.

And that’s why I am willing to share with you a guide on how to do it correctly.

  • The first step is to prepare the windshield for cleaning and removal. This includes parking your car in a shaded area and raising the wipers.

 

  • Proceed to wet the windshield.

 

  • Wash the windshield thoroughly with some car wash shampoo.

 

  • Rinse it off with water.

 

  • The above step may remove worn-out glass treatments. However, there may be some residue left. And that’s when it’s time to bring the big guns. A windshield glass cleaner can remove all silicone coats from your windscreen. Make sure that you get a quality auto glass polish that will be gentle on your car. An example is the Duragloss 755 Auto Glass Cleaner.

 

  • Clean the wipers and if they are worn out, you may have to replace them.

After removing all the Rain-X from your windscreen, you have two options. Either re-apply some new Rain-X or leave your windshield as it was. This will depend on your experience with Rain-X.

What about Removing Stubborn Rain-X?

If the Rain-X on your windscreen is proving hard to remove, then you can result to the following alternatives;

  • The best alternative to car wash soap is a Rain-X X-Treme Glass Cleaner. It will remove the treatment as well as any haze or discoloration from your windscreen.

 

  • A clay bar can also remove stubborn Rain-X.

 

  • Paint thinners also do a great job at getting rid of Rain-X.

 

  • The last option is using a sharp razor knife. I wouldn’t recommend this because many things can go wrong.
