How to Use Air Conditioning in Winter Without Fogging Up?

[MacJason]

Using the warm air from the air conditioning to defog. In winter, when we start the car and the water temperature rises to normal, we turn on the warm air, which blows out hot air. Press the defog button to direct the warm air towards the front windshield, achieving the defogging effect. Apply soapy water to the inside of the car window. Mix soap and water in a 1:10 ratio, then use a highly absorbent cloth to dip into the solution and wipe it on. First, it's impossible to wipe with a cloth while driving, and reaching the windshield is difficult. Even if a passenger helps, the wiping process can obstruct the view, and water marks may remain after wiping.
