How to Deal with Fogging Inside Car Windows?
2 Answers
Solutions for fogging inside car windows: 1. Open the windows: Fogging occurs due to the temperature difference between the inside and outside of the car. Opening the windows for ventilation will quickly dissipate the fog; 2. First turn on the cold air, then switch to warm air after the fog clears: Cars come with a defogging function. Cold air rapidly lowers the temperature of the windshield, preventing fog from forming, while warm air ensures the driver doesn't feel cold; 3. Use a cloth to wipe: Many drivers often wipe the fog off the windshield with a cloth while driving to maintain clear visibility; 4. Anti-fog solution: Dilute dish soap with water in a 1:6 ratio, then apply it evenly to the windows with a cloth or spray bottle. Once dry, wipe it off with a towel.
I've been driving for over twenty years, and dealing with foggy car windows is a common occurrence. This usually happens when it's cold outside and warm inside, combined with moisture from breathing or wet clothes, causing condensation on the glass. To handle it, I immediately turn on the A/C button for dehumidification, which works super fast; then adjust the vents to blow directly at the windshield with higher fan speed. In winter, don't rush to turn on the heater—first use cold air to defog before switching, to avoid making the fog worse. Remember to use the external circulation to bring in fresh, dry air, and sometimes cracking the window a bit helps. For prevention, I make a habit of keeping the car interior dry, wiping the windows before driving in winter, and avoiding smoking or placing wet items inside. Foggy windows while driving can be dangerous—if visibility is poor, slow down promptly and pull over safely to deal with it.
