How to Prevent Fogging on Car Windows?
2 Answers
Here are several methods to prevent fogging on car windows: 1. Wipe with a towel: Using a towel to wipe off the fog is the fastest way to remove it, but you need to stop the car first. Wiping the fog while driving can distract your attention and affect driving safety. 2. Open windows for convection: Utilize the convection method by opening the windows slightly. Fogging occurs due to the temperature difference between the inside and outside of the car. Opening a window gap allows the incoming air while driving to lower the interior temperature, causing the fog to dissipate naturally. 3. Use the air conditioning defogging function: Most cars come with a defogging feature. Simply turn on the window defogging function to use it.
I really hate it when my car windows fog up, especially on rainy days or in winter. As soon as I get in the car, it's like looking through a foggy lens. I usually use the defogging function of the air conditioner—right after starting the car, I adjust the temperature to slightly warm, turn up the fan speed, and direct it toward the windshield. It clears up in just a few minutes. You can also turn on the external circulation mode to reduce moisture buildup inside the car while cracking the windows slightly for ventilation. Anti-fog spray works great too—just spray and wipe it evenly on the glass to create a fog-resistant layer. Daily habits like not bringing wet umbrellas into the car and regularly cleaning the inside of the windows to prevent dust buildup also help. These methods are cost-effective and efficient—I've used them for years with no issues, keeping my vision clear. Don’t underestimate this small detail—it makes driving much safer.
