5 Best Windshield Water Repellents

To provide a safe journey in the winter season, we’ve reviewed a number of water repellents to find the best ones.

Here goes a short review of our selected products.

1. Aquapel Glass Treatment by PGW

Rain can be really dangerous for drivers. Even a light-rain increases the risk of an accident by 34 percent. So, protecting the windshield from rainwater should be one of the first priorities for every driver.

And that’s where the Aquapel rain repellent rocks. It’s a completely harmless solution to protect your windshield from the raindrops.

Besides, Aquapel Glass Treatment is quite easy to use. It doesn’t take more than 15 minutes to complete the whole application process. If you are a professional user, you may require even less. Despite thinking about the time, make sure that your glass gets clearer.

When the cleaning session is completed, it’s time to dry the glass. And the paper towels work better than microfibers. Paper towels can absorb comparatively more water. But, microfibers lose absorbency when those get wetted.

To assist you in the whole cleaning process, Aquapel includes 6 individual packs in this single package. Each pack contains enough spray to clean a full windshield. You can clean each window of two separate cars by using the whole package.

However, try to apply it in the cool shade to get the best result from this water repellent. Direct sunlight dries the solution quickly and makes the application process harder.

  • Enough for two cars
  • Easier to apply
  • Causes rain to bead up
  • Makes the windshield crystal clear
  • Won’t harm the rubber or paint

2. Rain-X 5071268 2-in-1 Glass Cleaner and Rain Repellant

Rain-X hardly ever disappoints its users when it comes to cleaning the windshield. Even before you start using this rain repellent, be confident that it will work for you. This cleaner is extremely easy to use and works comparatively faster. Simply spray it on the windshield, wipe away, and you’re done!

The Rain-X Glass Cleaner repels rainwater by making the water to bead up and rolls away. It removes every single water drop from your windshield and door glass. Plus, you can expect amazing results while using it on the headlights too.

When it comes to a glass cleaner, no other cleaner can do the cleaning task as good as Rain-X. The traditional cleaners generally leave streaks or swirls on the windshield.

But, Rain-X automotive glass cleaner removes almost everything from the windshield, such as snows, ices, road sprays, or other annoying road streaks.

However, this spray may fog up in humid conditions. Stay aware of that.

[wpsm_column size=”one-half”][wpsm_pros title=”PROS:”]

  • Streak-free
  • Easy to apply
  • Wipes off any residue

3. Hendlex Glass Pro Car Windshield Water Repellent

Most of the people use ceramic or silicone-based formulas as the water repellent. These formulas also work well but not worthy enough. To get the best out of your water repellent, you must choose a good repellent.

And as the third best windshield water repellent, we are representing the Hendlex Glass Pro that works on the molecular level.

Hendlex uses nano-particles to build this solution. These nano-particles stick deeply to your car windshield and remove everything from the glass. Because of working on the molecular level, it stays longer on the surface.

You can apply this coating on a wide range of surfaces such as car windshield, motorcycle helmet visors, or other automotive glasses. This 1.6 fl oz is enough for covering approximately 107 square feet.

The Hendlex coating stays totally invisible on your windshield. It also doesn’t change the surface color even a little. Thus you’ll get a clear view through the glass.

However, you have to follow some rules while applying this solution. Make sure the surface is dry, grease-free, and clean. Apply it by using a good microfiber and before getting dried.

Generally, it takes 30 to 60 seconds to get dried completely. Thus you must apply it within 30 seconds. But you have nothing to worry even if the coating gets dried. Just repeat the coating process, and you are good to go.

The perfect temperature for applying this coating is 41°F to 86°F. And after applying the coating properly, makes sure you’ve stored the rest of the solution in a tightly closed container. It protects the repellent from the direct sunlight or frost.

[wpsm_column size=”one-half”][wpsm_pros title=”PROS:”]

  • Easy to use
  • Stays totally invisible
  • Stays longer on surface
  • Built with nano-particles
  • Works on a molecular level

4. Gtechniq G1 Clear Vision Smart Glass

Gtechniq G1 works smartly, unlike the other rain repellent coatings. It uses a chemical bond to stay adhered to the surface rather than the physical bond.

The chemical bonding of G1 offers unparalleled function and durability to your car windshield. Besides the windshields, you can also use it on shower screens, marine glass, helmet glass, or any other thing where maximum visibility is required.

After applying the G1 well, you can repell up to 30,000 miles of dirt, ice, and water drips. It increases the visibility of the driver and helps to drive safely in any weather condition. Gtechniq G1 can keep your windscreen protected up to 2 years!

With the 100ml kit, you can coat about 13 to 18 vehicles. By the way, it depends on the size and number of glasses on your vehicle.

Because of the Proposition 65 Warning of the State of California, you can’t use it there. Rather than that, you are good to use anywhere you want.

Factors That Determine Windshield Treatment Longevity

Longevity of any product is the most important factor one usually considers before he buys a product. Same is the case with windshield water repellent. Predicting how long a product would last could be tricky and it requires a lot of research as well. The longevity of the windshield water repellent depends on various factors and it depends on the vehicle you have too. Some of the most important factors are as follows:

1. Car Parking Location

One of the most important factors of concern is where you usually park your car and it is extremely important in maintaining the protective coating on your car. The ideal place to park your car is away from the sun, moisture, dirt and under proper shade. When you are at work or you are out during the day for whatever reason, a good parking spot comes in handy and it pays off when your car is parked in a suitable location. 

When your car is parked under the sun, with moisture and dirt present, your product could break down faster than usual. Not only does the parking spot matter when you are outside, it matters when you are at your home too. There must not be dirt in your garage or wherever you park your car. Make sure that your vehicle is as much away from the sun as possible. 

2. Wiper Usage Frequency

Another thing to ensure longevity of your windshield is to never use the wiper when the windshield is dry. Furthermore, the case worsens when you use the wiper on a dirty surface. You must use the wiper only when you necessarily have to, and never use it on a dry surface. 

Your screen could be damp with the rain or you could also use washer liquid’s shot to ensure the presence of sufficient lubrication. With this, you can keep the sheet for a long time without bringing in much damage to it. 

When you are driving within the city, the rain repellent coatings are hit because the wipers will be used at a slower pace. However, when you are driving on the highways, your rain repellent coatings will incur the least damage because the wind speed will blow off the dirt and other elements which are present on the surface. 

Factors That Determine Windshield Treatment Longevity

3. Surface Preparation

The durability of your car is how well you have prepared your car under all conditions. Usually, there are three steps in proper preparation of your screen. The first step that you need to take is cleaning of the screen using some proper solution. With this, you will be able to clean off the visible first on the surface of your windshield. 

The next step involved here is to clay bar it, because with that, the elements which are harder to clean will be sucked off. You, however, must make sure that you come up with the right clay bar before you get started with this. The method usually works on surfaces such as metal, glass, paint, and fiberglass. 

The last step involved here is to polish the surface with the proper equipment or with your own hands. Here, you will be able to eliminate the minerals and water spots which could be present on the surface. If they are not taken care of properly, they might get stuck under the coating which would break it from the inside. Once done, remove the excess polish off of the surface. 

4. Windshield’s Age

When you have a new car, you know that the surface of the car will be smooth and uniform and the products will stick firmly and have a good grip for a while. You do not have to do much yourself here. However, with the older cars, the case turns to be a little different because the windshield of older cars is usually full of scratches, of which some are visible to the naked eye while you might not notice some when you take a glance at it. A scratch, no matter how small, will always cause you problems in the long run. The perfect solution for this is nothing but regular use of the rain repellents. In such a case, the surface of your car will be damaged at turtle speed, making things better and easier for you.

Windshield Treatment: Features To Look For

Anti-freeze Property

The presence of anti-freeze elements in your windshield treatment is a vital factor to consider before you select one for yourself. It is an essential factor to consider if you are travelling to the places which are snow-covered. If you plan to drive around the places with balmy weather, then the anti-freeze properties are not much of a significance to you and your decision to buy windshield treatment.  

You have to improve your anti-freeze game in case the liquid suggests some considerable amount of dilution. What you need to do in such a case is to grab 90% proof alcohol and make up for the dilution. Thus, you must keep this in mind before you get your next vehicle for freezing weather. 

No Scent

When it comes to the rain repellent liquid odour, different people prefer different scents. While we enjoy the floral and other fragrances, some enjoy a powerful citrus smell, connecting their brain with extreme cleanliness. With this, the users get a clean and fresh feel every time they wash their car. However, there is also a portion of the population which likes a windshield treatment with no scent and for us, that is the best of the lot for a few reasons.

With no scent, your nostrils would be clear of the strong odour of your windshield treatment on a bright day. You can drive around the town without being distracted by the strong scents of the windshield treatment. However, it is more of a personal choice and if you like the scent, you could go for it and if you do not, then the windshield treatment with no scent would be ideal. 

Windshield Treatment: Features To Look For

Dilution Ratio

Another feature you must consider is the dilution ratio. There are a couple of questions which need to be answered and different people prefer a different choice. Do you prefer a time concentrated bottle which gives you multiple batches of washer reservoir’s solution with proper dilution? Or do you prefer to get yourself a properly rationed diluted solution to use it directly? It all depends on what your choice is and we suggest you make sure that you know what you prefer. In case you are not sure, we recommend you to try both these solutions at least once and then come to a conclusion. 

It is advised that you go with the one which did not give you a nightmare of an experience and if you hit the wire with mixing the right proportions, then you could always get yourself an excellent deal with the concentrated formulas. 

These are a few of the most important things which you must consider before you buy yourself a windshield treatment. This would be extremely helpful for you, especially when you are looking to make your next purchase.

Things To Consider Before Buying A Windshield Water Repellent

A clean windshield is always the first priority while driving in rainy weather. And only a good windshield repellent can do that job for you. Let’s have a look at what you should check before buying a repellent.

Water Repellency

Proper water repellency is the key indicator that you have purchased the right product. A proper water repellent product will keep your windshield clearer while driving in poor weather conditions.

Scratch Resistance

The repellent sprays remove not only the dripping water but also the ice or other strains too. To do this, the manufacturers create a protective layer on the windshield.

It prevents your windshield from getting scratched. On the other hand, the low-quality repellents cannot keep your glass as scratchproof as expected.

Ease of Application

There’s a variety of application methods for applying the water repellents on the surface. In general, nanotechnology-based water repellents are quite challenging to apply.

Reapplication Frequency

Not every product comes with the same lifespan. In general, the silicon-based products do not last long. You have to reapply it several times a year. On the contrary, nanotechnology-based repellents don’t require frequent application.

Frequently Asked Questions (FAQs)

Q. What makes a good water repellent?

A good water repellent must satisfy the following characteristics:

1. Must be durable
2. Don’t require frequent reapplication
3. Won’t contain any toxic elements
4. Can clean the windshield properly
5. Improves visibility through the window

Q. Can I use the water repellent on my solar panels?

It depends both on your solar panel and the water repellent you are using. However, if the solar panel is made of nonporous elements, you can use it on the panel.
It is recommended to read the user manual of your solar panel before applying the repellent on that.

Q. Can I use these water repellents on the inside window?

Yes! The water repellent works well with the window glasses. It doesn’t matter whether you’re using it on the inside or outside the window.

Q. How long does the water repellent last?

The lifespan of a water repellent depends on the coating category.  Usually, the silicone-based repellents last for 4 to 6 months only. And the nanotechnology-based coatings last for more than a year.

Q. Does the windshield age affect the efficiency of the repellent?

The condition of your windshield is more important than the age. If your car windshield doesn’t have any crack or scratches on it, it won’t affect the efficiency.

A Final Word

Whether you go for a camping or driving in the rainy season, it’s mandatory to keep the windshield clean.

If you are hunting for the best windshield water repellent, hope that you’ve found the sure-shot. Choose one today and start exploring nature without worrying about the protection from bad weather.
