How to Deal with Fogging on the Outside of Car Windows?

[Gretchen]

To address fogging on the outside of car windows, you can use the windshield wipers to wipe it away. If the fog is heavy and the wipers are not effective, you can also use warm air to blow onto the windshield. Adjust the directional switch to direct air toward the glass, and the fog will disappear shortly, with very noticeable results. Below are detailed explanations regarding fogging on the outside of car windows: Causes of fogging on the outside of car windows: Fogging occurs on the outside during rainy summer days because the external air humidity is high, but the temperature is not low. When humid air comes into contact with the cooler glass, water vapor condenses into tiny droplets, forming fog on the outside of the glass. The principle is similar to fogging on the inside of windows in winter, which happens due to high humidity inside the cabin meeting the cooler glass. Therefore, in summer, if the air conditioning is on, the windshield becomes cooler and more prone to fogging. Methods to remove fogging on the outside of car windows: Glass defogger: Simply spray it evenly on the glass surface and wipe it clean with a dry towel; Air conditioning defogging: For manual air conditioning, turn on the front window defogging mode, set the fan speed to maximum, turn on the AC switch, and adjust the temperature to the lowest. For automatic air conditioning, usually just press the one-touch defrost button, after which the fan speed automatically increases to maximum and the external circulation is activated; Homemade defogger: Mix dish soap and water in a 1:6 ratio, pour it into a spray bottle, spray it evenly on the glass surface, and wipe it clean with a dry towel.
