What to Do When Car Windows Fog Up on Rainy Days?

[Teri]

When the front windshield fogs up on rainy days, the defogging methods are as follows: 1. Turn on the car's defroster: Activate the defroster while pressing the compressor (A/C) button, which will lower the temperature inside the car. This may feel cold in autumn and winter, but the defogging effect is noticeable. 2. Turn on the warm air from the air conditioner: Increase the airflow slightly. The dry, warm air will evaporate the water molecules in the car's interior, preventing fog from forming on the windows. 3. Purchase dry anti-fog wipes: Before use, wipe the car windows with a damp cloth or apply the wipes directly when fog appears. This can prevent fogging for up to 24 hours. 4. Purchase wet anti-fog wipes: Wipe the fogged areas directly, which can also prevent fogging for up to 24 hours. 5. Purchase anti-fog spray: Spray the glass anti-fog agent directly onto the front windshield. The anti-fog effect typically lasts about 10 days, with high-quality products even lasting up to a month, far outperforming anti-fog wipes.
