How to Deal with Foggy Windshield When Using Air Conditioning in Summer?

[SanWalter]

While driving, you can slightly open the windows to ensure air circulation inside the car, balancing the temperature inside and outside the vehicle. Here is some relevant information: 1. In summer, the air is relatively humid. When the air conditioning in the cabin has been on for a while, the temperature inside the car drops, and so does the temperature of the windshield. When the windshield temperature falls below the dew point of water vapor, the moisture in the air condenses, forming tiny water droplets on the glass. These droplets connect to form a thin layer of fog. 2. In case of a foggy windshield, you can spray an anti-fog agent to eliminate the fog on the glass. Spray a small amount of anti-fog agent on the car glass and wipe it clean. This forms a thin protective film on the glass, effectively preventing moisture from condensing into a foggy layer.
