Rainy seasons bring joy to most people, it annoys the hell out of car enthusiasts because with rain comes the excessive water spots on the exterior and the wind shields. Cleaning water from the exterior of the car is a tough task for sure, but it could be wiped out with extreme care. But, cleaning water from the windshields is a whole cumbrous experience even after having windshield wipers.

Windshield wipers clear the water but it doesn’t retrieve the 100% visibility as it should have which is very hazardous. A good driver should never compromise on the visibility while driving because one wrong move could cost you the lives of your loved ones.

If you are also a careful driver who is tired of cleaning windshields every morning to ensure a safe drive, then don’t you worry. We have got the solution to your problem and that is Windshield Water Repellent.

What Is A Windshield Water Repellent?

A windshield water repellent is a layer of coat applied to the windshield of a car that repels water and lets it slide off easily off the surface of the glass. The same as the protective wax/coating layer on the surface of your vehicle that not just preserves the paint of the vehicle but also pushes off the water, in turn avoiding swirls, scratches and water spots

The windshield repellent basically consists of hydrophobic properties which repels water by reducing the polarity of the glass made up of silicon and oxygen atoms. The non-polarity in the repellent is either attained by PDMS or by FAS chemical structure.

What Are The Benefits and The DrawBacks Of Using A Windshield Water Repellent?

Benefits Of Using A Windshield Water Repellent

Out of the number of advantages of windshield water repellent, the most important one is the increased visibility, which is a prerequisite of a safe ride. The several other benefits of using a windshield water repellent are as follows:

  • Less Water Spots

Water spots are something that annoys the car owners most as it ends up with nasty looking swirls and scratches. Using a water repellent, slides down the water easily from the windshield resulting in less water spots and of course less cleaning.

  • Easy To Clean

Windshields with water repellent coatings are much easier to clean. Be it the birds poop, or the bug splatter, no more scrubbing and efforts are required for a spotless windshield.

  • Instant Reaction from Drivers

With the increased coating the reaction time of drivers also increases by 25% which is essential for a safe ride. Be it the rain or haze, it allows the drivers to see clearly decreasing any existing chances of accidents at all.

  • Long Lasting WindShield Wipers

Protecting the windshield of your car with a water repellent decreases the requirement of using excessive windshield wipers even during harsh rains, which in turn increases the life of the windshield wipers saving you the extra cost.

Drawbacks Of Using A Windshield Water Repellent

The only drawback of using a rain/water repellent on windshields or windows of a vehicle is that it can easily wear out in some time in turn requiring another coat to last longer.

Comparing Different Types of Windshield Water Repellents

Not all water repellents are the same, and their effectiveness can vary depending on the active ingredients and application methods. For instance:

  • Silicone-Based Repellents: These are often long-lasting and highly effective in rainy weather but may be pricier.
  • Alcohol-Based Repellents: Easier to apply but might require more frequent reapplications, especially in areas with heavy rainfall.
  • Additive-Based Repellents: Such as those added to washer fluids, are convenient but may not offer the same longevity as direct applications.

Knowing which type best fits your needs—whether you prioritize longevity or ease of application—can help you select the most suitable repellent.

FAQs

Can you just put water in windshield wiper fluid?

You can but water wouldn’t provide you with the desirable result so it’s useless. Water won’t be able to remove bugs, tar, bird dropping or any other tough stain. However, if the temperature in your area doesnt get down to freezing than plain water might do the task.

Is it okay to use water repellent on windows of the vehicle?

Yes, it definitely is. If you have some extra repellent left then you can always apply it on the windows of the vehicle. However, it is not preferred as most of the repellents are costly and are mainly used to improve the visibility, which is not required in windows. So, it’s your choice.

Can we just use plain wipers to remove the dirt or tree sap from the windshield of the car?

No, never use the plain wipers to remove the dirt or dust as without water it would not only get messy but would also end up scratching the glass of the windshield which no car enthusiast would like.

When should we change the windshield wipers of our vehicle?

When you feel like there is no difference in cleaning with or without wiper, that’s the time for you to replace your old windshield wipers before it scratches your glass.

Can I apply windshield water repellent in extremely cold temperatures?

For best results, it’s usually recommended to apply repellents when temperatures are above freezing, ideally between 50°F and 90°F (10°C and 32°C). Cold temperatures may cause the repellent to apply unevenly and reduce its durability.

How often should I reapply a windshield water repellent?

Reapplication depends on the product, climate, and frequency of use. Most repellents need to be reapplied every 1-3 months, especially in areas with heavy rainfall. Some high-end products might last up to 6 months under optimal conditions.

Is there a difference between water repellent for windshields and other car windows?

Yes, windshield-specific repellents often prioritize visibility and durability in high-speed conditions, whereas products for other windows may focus more on basic water-beading. Always choose a product labeled for windshield use for the best driving safety.
