What to Do When the Windows Fog Up?

[LeLondon]

Here is the relevant introduction about car window fogging: 1. Air Conditioning Defogging: 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 adjust the temperature to the lowest. The fog on the windows will disappear shortly. Additionally, some models have electric heating for the rear window and side mirrors. Simply press the switch, and the fog will clear in about a minute. Many vehicles now also feature a one-touch defogging function, which is convenient and quick to use when fogging occurs. 2. Air Convection: This method is suitable for very few situations. Opening the windows increases air convection, reduces the temperature difference inside and outside the car, and weakens the conditions for fog formation. While this method seems economical, it is rarely practical. For example, if it is raining outside, you cannot keep the windows open, and the incoming air is quite limited. 3. Defogging Spray: Simply spray it evenly on the glass surface and wipe it clean with a dry towel. The principle involves using surfactants to leave a protective film on the glass surface, altering the surface tension of water molecules, causing fog droplets to coalesce into larger droplets that do not obstruct vision. This can also be applied to other car windows, especially the side mirrors. 4. Homemade Defogging Spray with Dish Soap: Mix dish soap and water in a 1:6 ratio, store it in a bottle, and spray and wipe before traveling. The effect is comparable to commercial defogging sprays, though the durability is slightly inferior.
