How to Deal with Fogging on the Outside of the Car Windshield?
1 Answers
Solutions for fogging on the outside of the car windshield are as follows: 1. Air Conditioning Defogging. This is the simplest and most effective method. Simply 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 setting to remove fog. Additionally, some models are equipped with electric heating for the rear windshield and side mirrors, which can eliminate fog in about a minute by pressing the switch. 2. Air Convection Defogging. Opening the windows increases air convection, reduces the temperature difference between the inside and outside of the car, and weakens the conditions for fog formation. This method is relatively economical but suitable for fewer situations. 3. Defogging Spray. The best method is prevention by using a defogging spray in advance. Its 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. 4. Homemade Defogging Spray with Dish Soap. If a defogging spray is not available, you can mix dish soap with water in a 1:6 ratio, put it in a bottle, and spray and wipe it before traveling. The effect is comparable to a defogging spray, but the durability is slightly worse.
