What to Do When Car Windows Fog Up in Winter?

[MacLucy]

When car windows fog up in winter, it is important to remove the fog promptly. Here are some methods: 1. Anti-fog spray method. Spray a small amount of anti-fog spray on the car windows, then wipe it clean with a towel to form a transparent protective film on the glass. This effectively prevents water vapor from condensing on the glass and forming fog, suitable for cold winters. 2. Air conditioning warm air method. In winter, use the car's warm air to blow hot air onto the glass, quickly raising the temperature and reducing the temperature difference between the inner and outer surfaces of the window. This effectively prevents fogging on the front windshield. 3. Window ventilation. When the fog inside the car is not heavy, you can open a small gap in the side windows to allow air to circulate between the inside and outside of the car, reducing the temperature difference and gradually dissipating the fog. However, window ventilation has certain drawbacks—it is not suitable during rain or snow, on highways, or when the fog is heavy, and it also lowers the temperature inside the car.
