However, along with your windshield wipers, you can also use some water repellent on the windshield to make driving in the rain much easier. Consider using one of these products to get the rain off your car.

What Is a Windshield Water Repellent & How it Works?

Windshield water repellent has a coating that is applied to the glass of your car. With the hydrophobic properties present in most water repellents, the coating will be able to repel the water by pushing it off the surface of the glass rather than allowing it to sit there. This allows you to have increased visibility when you are driving in both the rain and the snow.

Water repellent is hydrophobic which means it does not like water. This is because the atoms and the chemicals in the water repellent make the oxygen electronegative. This gives it the properties it needs to repel water.

The properties in the water repellent also make it polar. This also makes it hydrophobic and able to repel water. This also makes the water droplets that hit the car form hard balls that more easily roll off the surface of the windshield rather than have it stick to the surface as you see on windshields that are not treated with water repellent.

You might also hear people talk about the surface angle when you hear them discuss water repellents. The properties of water repellent make the surface angle of the water that hits your windshield bigger. The contact angle or surface angle will determine if the water repellent is efficient or not. Knowing the contact angle of the water repellent will be able to help you determine whether or not you are buying a quality repellent or not. Higher contact angles mean higher water-shedding, which you want when looking for water repellents.

Getting a water repellent with hydrophobic properties is necessary to ensure it works properly and does its job. In addition, when you have a water repellent with high contact angles, you will have significantly increased visibility. Droplets running off and being repelled by the car make it much easier to see through the window than the rain that hits the windshield at high speed when you are driving through a rainstorm.

It also works for snow and ice as well as rain. So, no matter where you live, you will benefit from having a water repellant because it makes it so much easier to drive. It also means fewer water spots on your windshield which keeps your car looking newer and fresh for longer. You can also use your windshield wipers less.

What are the Benefits of Using a Water Repellent?

There are many benefits when it comes to using a water repellent. Here are some of the main ones to consider when you are looking for the right product:

  • Improves visibility. Driving in the rain can be challenging. It’s also hard to see the road, especially in downpours. Wipes can also smear dirt and grime around the window, making it harder to see. Most water repellents will add a protective coating around the window to ensure the dirt cannot be pushed around.
  • Easier Cleaning. You probably know that it becomes harder and harder to clean the windshield each time it rains because of all the dirt and water. Without dirt being able to stick to the window, though, you can be sure cleaning your car will be much easier. You will even be able to clean with glass cleaner.
  • Allows you to drive safer. Some people even avoid the roads in the rain, especially if their windshield wipers do not work correctly. Having a water repellent will be able to let you drive more confidently. It also makes your view much clearer.
  • You can drive without your wipers. Some people choose to drive with wipers and water repellent. You can always do both, but you don’t have to in most cases. The coating from the spray will make sure that your windshield repels all water. This will allow your wipers to last longer because you don’t have to use them as often, and they don’t have to work as hard when you do use them.
  • It makes driving easier. If you’re afraid of driving in the rain, this can remove some of the fear and nervousness. Just make sure you still drive slowly and allow yourself time to get used to the repellent to be sure you can see the road.
