What to Do When the Car Fogs Up in Rainy Weather?

[McAlexander]

Here are the methods to deal with car window fogging in rainy weather: 1. Preventive measures such as applying anti-fog spray: Spray a small amount of anti-fog agent on the car windows (inner side) and wipe them clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed on the surface, which effectively prevents the formation of fog caused by moisture condensation, especially suitable for cold winters. Alternatives to anti-fog spray include dishwashing liquid, soapy water, glycerin, alcohol, or salt water. After drying, wipe off excess residue with chamois or a soft dry cloth to ensure the car windows remain fog-free for several days. 2. Air conditioning cooling method: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and eliminate fog. In summer, especially when multiple people enter the car, if the air conditioning is not turned on promptly, the high humidity from exhaled breath can quickly cause the windshield to fog up. At this point, turn on the air conditioning to blow cold air onto the windshield. Using the dehumidifying function, the fog on the windshield can be removed quickly. However, if the humidity is too high and the air conditioning is not effective enough, slightly open a window to rapidly reduce the humidity inside the cabin. Of course, combining both methods can yield faster results.
