Which Button to Press for Defogging on Rainy Days?

[EllieRose]

The quickest method to defog the car interior on rainy days is to activate the front window defogging mode, then turn on the air conditioning (A/C) switch, and set the temperature to the lowest. This will quickly remove the fog. Below is an introduction to anti-fog agents: Spray Anti-Fog Agent: When using an anti-fog agent, the owner only needs to spray it evenly on the glass surface and then wipe it clean with a dry towel. After wiping, a protective film will remain on the glass surface, altering the surface tension of water molecules and causing fog droplets to coalesce into larger water droplets, thereby not obstructing the view. This method is also suitable for other car glass, especially the exterior rearview mirrors. Homemade Anti-Fog Agent with Dish Soap: If you forget to buy an anti-fog agent and need a temporary solution, mixing dish soap with water is a good alternative. Mix dish soap and water in a 1:6 ratio, put it in a bottle, and spray and wipe before traveling. The effect is comparable to commercially available anti-fog agents, though the durability is slightly inferior.
