How to Deal with Foggy Car Windows at Night?
2 Answers
If the fog inside the car is not too heavy, opening the windows on both sides will create air convection inside the vehicle. Spray anti-fog solution onto the inner surface of the car windows and wipe it clean. This not only removes dirt from the glass but also forms a thin, transparent protective film on the surface. Most cars equipped with air conditioning have a defogging function. Simply press the defog button lightly. Mix dishwashing liquid with water (ratio of 1:6), apply it evenly to the car windows with a sponge, and wipe it clean with a car towel once dry, leaving no water stains.
Foggy car windows are a common issue, and as a seasoned driver with years of experience, I've figured out a few practical tricks. One late winter night after work, my windshield suddenly fogged up, making it impossible to see anything. I quickly turned on the heater to blow warm air onto the windshield, paired with the external circulation mode to quickly remove the moisture. The fog cleared in less than a minute. If it's hot outside, using the air conditioning works just as well. Prevention is key—I regularly use anti-fog spray bought from the supermarket on the interior glass surfaces to reduce fog formation. Always remember to adjust the fan direction correctly; avoid blowing air directly at people to prevent increasing humidity. In emergencies, pull over and wipe the windows clean with a cloth before driving again—never skip these few seconds, as safety is more important than anything. Also, keeping fewer damp items like umbrellas inside the car can help reduce the risk of fogging.
