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

[OSara]

Utilize the method of reducing temperature difference to eliminate fogging. In winter, direct warm air onto the windows using the heater to quickly raise the temperature and reduce the temperature difference on the glass surface. Apply an anti-fog agent evenly on the windows and wipe it clean, forming a transparent protective film on the glass to prevent fog formation. Crack open the side windows slightly to allow air convection inside the car, gradually equalizing the interior temperature with the outside temperature, which will help dissipate the fog. Mix dish soap with water, apply it evenly on the interior glass with a sponge, and after it dries, wipe it clean with a car towel, leaving no water stains.
