Learn more about windshield condensation

You’re happily on your way on a chilly morning until you notice your car windows steaming up. No one likes the blurry film obstructing your vision when all one needs is a peaceful and unhindered drive.


Let Eastern Shore Toyota explain why this happens and possible remedies to deal with condensation on car windows.


  1. 1. Why Is There Moisture On My Car’s Windshield?

The first thing to clarify is that condensation is different from frost. Frost forms when the temperature outside is below freezing and moisture in the air bonds with your windshield. You can usually eliminate frost by turning on your car’s defroster.


On the other hand, condensation happens when humidity in the air turns into water droplets on a colder surface. So, when you get in your car on a cold, humid day, the warm air from inside your vehicle meets the cold glass of your windshield and causes condensation.


2. The Chemistry Of Condensation

Condensation occurs when humid air hits a cold surface. The water molecules in the air bind with the molecules on the cold surface, forming tiny droplets of water. These droplets stick together and settle down on surfaces causing your car windows to steam up.


There are a few things you can do to prevent condensation from forming on your car windows:


  • Keep your windows clean & free of any invisible debris
  • Use an anti-fog solution on your windows
  • Wipe your windows down with a clean cloth regularly
  • Keep your car well-ventilated by opening the windows slightly when driving
  • Park in a garage or undercover to protect your vehicle from the elements


3. Prevent Foggy Car Windows While Driving

While you can’t do much about cleaning the fog as you’re driving, we still have a few tips that will help you lessen the agony:


1. Turn On the Defroster

If your car comes equipped with a defroster, you can use it to help clear the steam off your windows. The defroster will direct warm air at your windshield, helping to prevent condensation from forming.


2. Crack Open a Window or Sunroof

This is another method you can try to lessen the impact of fogging as you drive. Open a window or sunroof slightly so the temperature and moisture content can balance with the external environment.


3. Adjust the Temperature of Your Car

You can also try to change the temperature in your car so that it’s not as humid. If your car has automatic climate control, set it to recirculate the air inside the cabin so that moisture isn’t being pulled in from outside.


Now that you have learned all the needed information on steaming car windows, we hope you will now be able to beat the fog and enjoy a clear view while driving!
