How to Defog a Car in Winter?
2 Answers
Methods to defog a car in winter include: 1. Open both side windows; 2. Turn on the air conditioning's external circulation; 3. Adjust the air vents to defog 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 for removal; 6. Wipe with a cloth dipped in dishwashing liquid or soapy water. The reason for fogging on the interior glass in winter is: The large temperature difference between the inside and outside of the car causes the higher temperature inside the cabin to condense moisture on the inner windshield, forming fog. Methods to prevent fogging on car interior glass include: 1. Wipe with an anti-fog cloth; 2. Spray anti-fog agent in advance.
Driving in winter with foggy windows can be really annoying. I find that using the warm air to blow on the front windshield is the most effective method—turn up the temperature and increase the fan speed, while also turning on the AC for dehumidification. The defog button is a lifesaver; just press it and it’s done. For prevention, regularly clean the windows and apply anti-fog spray to reduce condensation points. Avoid placing wet clothes or hot drinks inside the car to prevent adding moisture. On cold days, warm up the engine for a few minutes before driving; when the glass temperature rises, it’s less likely to fog up. Safety first—if the fog is too thick, don’t drive; clear it completely first. Sharing years of experience, I always keep a bottle of anti-fog spray in the car, which comes in handy during business trips or long drives. Remember to switch between recirculation and fresh air modes: use fresh air to expel moisture and recirculation to retain warmth. Keep the wipers clean to prevent clogging.
