How to Deal with Fogging on Side Windows?
3 Answers
Here are solutions for fogging on side windows: 1. Anti-fog Spray Method: Spray a small amount of anti-fog agent on the car windows, then wipe it clean with a towel to form a transparent protective film. This effectively prevents water vapor from condensing on the glass and forming fog, suitable for cold winters. 2. Air Conditioning Cooling Method: Turn on the air conditioning to blow cold air towards the windshield, utilizing the car's air conditioning dehumidification function to reduce air humidity and remove fog, suitable for humid summer weather. 3. Air Conditioning Heating Method: In winter, use the car's heater to blow warm air onto the glass, quickly raising the temperature and reducing the temperature difference between the inner and outer surfaces of the window glass, effectively preventing fog formation on the front windshield.
As a seasoned driver with years of experience, I've encountered foggy windows countless times and now handle it with ease. The first thing I do is start the car and press the defrost button to direct airflow onto the windshield. If the car has automatic climate control, it's even better—just press AUTO and it will adjust temperature and humidity to clear the fog. The root cause of fogging is the condensation of moisture when warm, humid air inside the car meets the cold glass, so cracking the windows slightly for ventilation also helps, but avoid opening them too wide to prevent noise and dust. I often use a soap-water solution to wipe the windows as an anti-fog layer, which keeps them fog-free for months. Prevention is key in winter—warming up the car for a few minutes before driving reduces temperature differences. If fog becomes severe enough to obstruct vision, immediately pull over and wipe the windows with a clean cloth—never force yourself to drive to avoid accidents. Develop good habits: keep the interior dry by avoiding wet items, and regularly check the AC system to ensure proper dehumidification. This way, you'll rarely face major issues while driving.
I drive a newly purchased economy car, and the fogged-up windows are particularly annoying. Now, as soon as I get in the car, I immediately press the defog button, set the fan to maximum blowing towards the windshield, and turn on the air conditioner's dehumidification mode to quickly solve the problem. If the fog is slight, I use the warm air mode to raise the temperature, which consumes less fuel. Fogging occurs because warm, humid air condenses when it meets cold surfaces. Simply opening the windows for ventilation can also disperse the fog, but the effect is slower. Anti-fog spray is a must-have for me—a quick spray easily solves the issue. For prevention, I wipe the windows once a week to reduce residue. Remember not to leave drinks in the car to humidify the air, and always clear the fog for safety before driving.
