What to Do If the Outside of the Windshield Fogs Up and Won't Go Away?

Solutions for removing fog from the outside of the windshield are as follows: Anti-Fog Spray Prevention Method: Spray a small amount of anti-fog agent on the car windows (inner surface), then wipe it clean to remove dirt and stains from the glass. While polishing the glass, a thin transparent protective film is formed on the surface, which effectively prevents the condensation of water vapor on the glass, thereby avoiding fog formation. Air Conditioning Cooling Method: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car, if the air conditioning is not turned on in time, the high humidity of exhaled air can quickly cause the windshield to fog up. Air Conditioning Heating Method: In winter, use the heater to blow warm air onto the glass, quickly raising the temperature of the front windshield. This reduces the temperature difference between the inner and outer surfaces of the glass, preventing excessive fogging. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to completely remove all the fog.
