How to Deal with Fogging Inside Car Windows?
2 Answers
Methods to handle fogging inside car windows: 1. Turn on the car's fan and air conditioning switch, and the cold air will blow onto the windshield, quickly clearing the fog; 2. If the fog is not heavy and it's not too cold outside, you can slightly open the side windows to allow air convection inside the car. This will gradually equalize the temperature inside with the outside, causing the fog to dissipate; 3. You can choose to use specialized anti-fog products; 4. You can use dishwashing liquid with a dry cloth to wipe. The specific method is to mix dishwashing liquid 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 watermarks. Generally, this can effectively prevent fogging for up to 20 hours.
When my car windows fog up while driving, I immediately turn on the air conditioning defogging mode—usually by pressing the defog button—and set the fan to maximum to blow on the windshield. Sometimes, I use warm air to help, as the heat quickly evaporates the moisture. If the car doesn’t have an AC function, I simply wipe the glass with a clean cloth or tissue, but I make sure to pull over safely before doing so. To minimize moisture buildup, I avoid eating in the car or bringing wet items inside. Recently, I learned to place a pack of activated charcoal on the dashboard to absorb humidity—simple yet effective. Remember to switch to the external air circulation mode to let in dry air instead of always using recirculation. These tips come from my daily rainy commutes.
