What Air Setting to Use for Foggy Windows in Winter?

[DeHope]

In winter, use warm air for foggy windows. Steps to turn on the heater: 1. Start the car; 2. Turn off the AC; 3. Wait until the water temperature rises above 40 degrees Celsius; 4. Turn the knob to the red zone to activate the warm air mode. The reason for foggy windows is: In winter, with the windows closed, moisture inside the car cannot evaporate, and the temperature difference between the inside and outside of the car is significant. When moisture meets the cold glass, it forms a layer of fog. Solutions for foggy windows in winter: 1. Apply anti-fog spray, which forms a transparent protective film on the glass; 2. Use the air conditioning's dehumidification function to reduce air humidity; 3. Use the warm air method from the air conditioning to minimize the temperature difference and eliminate frost on the windows.
