How to Deal with Foggy Car Windows?
2 Answers
Solutions for foggy car windows include: 1. Open both side windows; 2. Turn on the air conditioning's external circulation; 3. Adjust the air vents to defogging mode; 4. In winter, use the air conditioning's cooling and dehumidifying function to reduce air humidity; 5. In summer, use methods to reduce temperature differences; 6. Wipe with a cloth soaked in dishwashing liquid or soapy water. Foggy car windows are caused by the temperature difference between the inside and outside of the car, where the temperature inside the cabin is higher than outside, leading to condensation of moisture on the inner windshield forming fog. Methods to prevent foggy car windows include: 1. Wipe with anti-fog cloths; 2. Apply anti-fog spray in advance.
When the windows fog up while I'm driving, the most direct method is to immediately turn on the air conditioning defogging mode after starting the vehicle, set the fan speed to maximum, and direct it at the windshield. Use warm air if the outside temperature is low, and cold air for dehumidification on hot days to quickly remove moisture. If in a hurry, use a clean cloth to wipe the inside while parked, but be careful not to scratch the glass. Dirty windows fog up more easily, so I regularly clean them with glass cleaner; applying some anti-fog spray is also very effective—spraying it in advance can reduce the problem. The main cause of fogging is high humidity inside the car combined with a large temperature difference, which the air conditioning is designed to handle—just select the defog button or fan mode. Maintaining proper ventilation is key; crack the windows slightly for airflow and avoid sealing them too tightly. Fogging is most likely to occur on rainy days, so taking action in advance can prevent blurred vision.
