How to Remove Fog from Car Windows?
2 Answers
Methods to remove fog from car windows include: 1. Preventive measures like spraying anti-fog agents. Spray a small amount of defogger on the car windows and wipe it clean to remove dirt and stains from the glass; 2. Air conditioning cooling method. Use the air conditioning's dehumidification function to reduce air humidity and eliminate fog; 3. Air conditioning heating method. Reduce the temperature difference to remove condensation. Note that whether the air conditioning is automatic or manual, turning it on helps with dehumidification. Avoid setting the air conditioning temperature to the coldest position, as prolonged use may cause frost to form on the outer side of the windshield.
Last winter while driving, my windshield suddenly fogged up and I could barely see the road. I quickly turned on the AC to defog. Using the AC is the fastest method: After starting the car, just press the windshield defog button (the one with the fan-shaped icon), and the AC will automatically increase airflow to blow on the glass. If you don’t have automatic AC, manually switch to external circulation + AC, set the airflow to blow on the windshield, and adjust the temperature to around 23°C for the best effect. Prevention is also key—I always keep a dry towel in the car for emergency window wiping and use a diluted dish soap solution to wipe the inside of the glass before driving, which forms an anti-fog film once dry. Also, aging door seals can let moisture seep into the car, so remember to check and replace them regularly—otherwise, fogging up mid-drive can be really dangerous.
