What Causes Fogging on the Windshield?
1 Answers
Fogging occurs due to the temperature difference between the inside and outside of the vehicle. Air Conditioning Defogging: This is the simplest method. Just turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and adjust the temperature to the lowest setting. The fog on the glass will disappear. Additionally, some models are equipped with rear window and side mirror heating. Simply press the switch, and the fog will clear in about a minute. Defogging Spray: When using, just spray it evenly on the glass surface and wipe it clean with a dry towel. Its principle is to use surfactants to leave a protective film on the glass surface, altering the surface tension of water molecules. This causes fog droplets to coalesce into larger water droplets, thus not obstructing the view.
