How to Quickly Remove Fog Inside the Car on Rainy Summer Days?

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 then adjust the temperature to the lowest setting. Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken fog formation. This method seems economical, but it is actually suitable for very few situations. When using it, simply spray it evenly on the glass surface and then wipe it clean with a dry towel. The principle is to use a surfactant method to form a protective film. Mix dish soap and water in a ratio of 1:6, spray and wipe before traveling, and the effect is comparable to commercially available defogging agents, although the durability is slightly worse.
