What Type of Air Should Be Used to Defog Car Windows?

[JaydenDella]

Both cold and warm air can be used for defogging. Here are the methods for defogging: 1. Air Conditioning Cooling Method: Utilize the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car without promptly turning on the air conditioning, the high humidity from exhaled breath can quickly cause the windshield to fog up. At this point, you can turn on the air conditioning to blow cold air and use its dehumidification function to quickly remove fog from the windshield. 2. Air Conditioning Heating Method: Use the method of reducing the temperature difference to remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the windshield, reducing the temperature difference between the inner and outer surfaces of the window glass, which can promptly prevent excessive fogging on the windshield.
