Your windshield fogs up when air of different temperatures mixes and condenses. In the summer, condensation is caused by warm outside air hitting your cold windshield. In winter it occurs when the warm air inside the car hits the cold windshield. Understanding how condensation forms can help you get rid of it, depending on the season. You can also take steps to prevent your windshield from fogging up.

To step

Method 1 of 3: Remove condensation from the windshield during hot weather

1. Turn down the air conditioner if it is hot outside. If you have fogged up windows in the summer, turn down the air conditioner. This will heat up your car, so that the temperature of the air inside matches that of the outside air better. You can also open your windows slightly to let outside air in (this will also keep your car from getting too musty).
2. Turn on the windshield wipers. If the condensation forms on the outside of the car (it does in summer), you can remove it with the windshield wipers. Turn them on at the lowest setting and leave them on until the condensation is gone.
3. Open your windows. This is the fastest way to get the temperature in the car equal to the temperature outside the car. Open your windows as far as possible so that the warm outside air can get into the cool car.

Method 2 of 3: Remove condensation from the windshield in cold weather

1. Change the air supply. Most cars have buttons that allow you to circulate the air that is already in the car or to draw in air from the outside. If your windshield fogs up, change the setting so that outside air is drawn into the car. Look for the button with a small car and an arrow pointing inward. Press it so the light above it is on.
   • Or press the button with a car and an arrow that goes around so that the light goes out. This turns off the function that circulates air inside.
2. Reduce the temperature in the car. Since batter is caused by temperature difference in the air, lowering the indoor temperature will help to reduce condensation. Turn the car's fan on to the highest setting and turn the temperature to as low as possible.
   • This is the fastest method, but also the coldest. Be prepared to shiver a bit!
3. Turn on the defrost function with cool air. The defrost function will direct the air to your windshield, the cool air will help to lower the temperature of the windshield to the outside temperature. This can help get rid of condensation on a windshield.

Method 3 of 3: Prevent a fogged windshield

1. Use silica litter. Fill a sock with silica litter. Close the end with a piece of string, then place one or two full socks close to the front of your dashboard. The moisture in the car is then absorbed overnight, preventing seizure.
2. Put shaving soap on your windshield. Use the type of shaving soap that comes out of the holder as foam. Spray a small amount on a soft cotton cloth and spread it over your windshield. Then use a clean, dry cloth to wipe it off. This should create a moisture barrier on your windshield, preventing seizure.
3. Leave the windows open if you can. If your car is in a safe place, leave your windows open about an inch.This allows outside air into the car, which can prevent the windshield from fogging up.
   • This method is best for the summer, as you obviously don't want to run the risk of ice or snow in your car in the winter.

Warnings

• Never reach out to wipe the windshield when the car is in motion. If you need to wipe the windshield and the wipers aren't enough, stop your car to do so.
