Fogged up car windows are one of the most common moisture problems. A car acts as a closed compartment and tends to retain a lot of moisture. Moisture that comes in does not easily go out again, which causes condensation on the windows. But no worries! Here are 5 things you might try to lower the humidity in your car to prevent condensation and moisture building up:
1. Ask your mechanic to check the door and window seals on your car.
The rubber weather stripping is there to keep moisture out of the car. Damaged or dried out rubbers can cause water to leak into the car.
2. Keep your windows clean.
Particles of dirt on the windows give water molecules a surface to attach themselves to. Therefore, it is important to regularly wipe the inside of your windshield and other windows with a clean microfiber cloth and window cleaner. Make sure the window cleaner you use does not leave a residue or you might actually worsen the condensation problem.
3. Air out your car regularly.
Leaving the car windows open for a few hours on a sunny day will allow part of the moisture that has built up in the car interior to escape.
4. Ventilate the smart way.
Using the car’s A/C and heater smartly will help you drive away quicker. Your windshield and windows will likely not be fogged up when you get in the car. Only when you turn on the ignition and air starts blowing on the cold windows do the windows start to mist up. It can help to switch off the blower for a few minutes until the engine, which supplies it with heat, has warmed up a little. The A/C removes moisture from the air, so switch it on. But remember — the A/C tends to be less effective at very low temperatures.
5. Place a small dehumidifier inside the car.
There are excellent non-electric dehumidifiers you can use in your car to prevent moisture from building up. Make sure to use a dehumidifier without calcium dichloride as these tend to leak a salty residue that might damage your car upholstery or its metal parts.
