How to Solve Fogging on the Outside of Car Windows?
2 Answers
Solutions for fogging on the outside of car windows are as follows: 1. Anti-fog spray method: Spray a small amount of defogger on the car window and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed on the glass, which can effectively prevent the condensation of water vapor on the glass and the formation of fog. 2. Air conditioning cooling method: Use the cooling effect of the air conditioning to reduce air humidity, thereby removing window fog. In winter, especially when many people are in the car, if the air conditioning is not turned on in time, the windshield will quickly fog up, severely obstructing the driving view. Using the air conditioning's dehumidification function can remove fog on the windshield. 3. Air conditioning heating method: Use the method of reducing temperature difference to eliminate fog. Quickly increase the temperature of the front glass to reduce the temperature difference between the inner and outer surfaces of the window glass, which can effectively prevent excessive fogging on the windshield.
Fogging on the outside of car windows is caused by condensation due to low external temperatures and warmth inside the vehicle, commonly occurring during large temperature differences between winter and summer or on rainy days. I often handle this situation by first turning on the air conditioning in defogging mode, increasing the airflow directed at the windows, and raising the temperature to quickly dry the fog. Avoid using recirculation mode to prevent the air from becoming more humid; instead, switch to fresh air mode to bring in drier air. When parked, use a clean cloth to wipe the glass surface, keeping it clean and free of dust buildup. For prevention, evenly apply soapy water or a specialized anti-fog agent to the glass to reduce the frequency of fogging. If severe fogging obstructs visibility while driving, immediately turn on the windshield wipers to assist in clearing it. On highways, stay calm and slow down to pull over safely. A good daily habit is to focus on cleaning the windows during car washes to avoid sudden temperature changes that could lead to unexpected risks, ensuring safer and more worry-free driving.
