How to Defog Car Windshield in Winter?
1 Answers
Methods to defog car windshield in winter are as follows: 1. Air Conditioning Defogging: Turn on the front window defogging mode, set the fan speed to maximum, switch on the A/C button, and then adjust the temperature to the lowest setting. The fog on the glass will disappear shortly. Additionally, some car models are equipped with electric heating for the rear windshield and side mirrors. Simply press the switch to activate it, and the fog will be cleared in about a minute. 2. Air Convection: Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation. 3. Defogging Agent: Just spray it evenly on the glass surface and wipe it clean with a dry towel. The principle is to use 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 method is also applicable to other car glass surfaces, especially the side mirrors. 4. Homemade Defogging Agent with Dish Soap: Mix dish soap and water in a 1:6 ratio and store it in a bottle. Spray and wipe before driving, and the effect is comparable to commercial defogging agents, though the durability is slightly inferior.
