What is the car defogging symbol?

[DanteLee]

The car defogging switch has two symbols: one for the front windshield and one for the rear windshield. Here is some relevant information about car defogging: 1. Proper usage: When there is fog inside the car, press the corresponding defogger switch, and the indicator light will turn on. After working for a period of time, the fog will disappear. The defogger will automatically turn off after exceeding the preset time. If the owner wants to manually turn off the defogger during the process, simply press the defogger switch again. 2. Preventing car fogging: Owners can always keep a defogging spray ready. The principle of the defogging spray is to use surfactants to leave a protective film on the glass surface, altering the surface tension of water molecules and causing fog droplets to coalesce into larger water droplets, thus not obstructing the view. When using it, simply spray it evenly on the glass surface and then wipe it clean with a dry towel.
