How to Defog Windshield in Summer?

[Lydia]

Slightly open the window to balance the temperature and humidity inside and outside the car, then turn on the defogging mode of the air conditioner. Here are some other methods for defogging: 1. Use the car air conditioner: Adjust the air vent to the windshield setting, turn on the air conditioner, engage the compressor, and set the temperature knob to the warm air position. This method not only defogs but also provides warmth. 2. Use anti-fog spray: Apply "car glass anti-fog spray" (such as Fog Fighter) to the inner surface of the car glass and wipe it clean. This not only removes dirt from the glass but also forms a thin transparent protective film on the surface, effectively preventing moisture condensation and fog formation. One application can prevent fogging for about 10 days.
