What to Do When There Is Fog Inside the Car While Driving?
3 Answers
Here are specific solutions for dealing with fog inside the car while driving: 1. Proper use of the air conditioning system. Park the car, turn on the air conditioning, adjust the temperature control to the warm air direction, and then press the defrost button to dry the fog on the windshield with warm air from the air conditioning. During defrosting, you can switch the air conditioning to external circulation to allow fresh air from outside to enter the cabin. Setting the compressor and fan speed to 25°C or higher can speed up the defrosting process. 2. Use specialized anti-fog products. Before each use, spray evenly on the windows and wipe clean to form a transparent protective film on the glass, preventing fog formation. One application can prevent fog for about ten days to half a month. 3. Open the windows to allow hot and cold air to circulate. When the fog is not heavy, you can open a small gap in the side windows to allow air inside and outside the car to circulate. As the temperature inside the car gradually matches the outside temperature, the fog will dissipate. 4. Use dish soap with a dry cloth. Mix dish soap with water in a ratio of 1:6, apply evenly to the interior glass with a sponge, and after it dries, wipe clean with a car towel, leaving no watermarks.
I've been driving for over 20 years and have encountered fogging issues many times, especially during rainy seasons or winter. The most urgent situation is when the windshield fogs up and obstructs visibility – extremely dangerous. I immediately press the defog button on the AC – usually marked with a front window icon – or manually increase the fan speed directed at the glass. Then, I slightly open a side window or sunroof for ventilation to reduce interior humidity, but not too much to avoid excessive noise or rain entering. For prevention, I regularly clean the interior surface of windows with a dry cloth to remove dust and prevent water accumulation; placing a car dehumidifier bag on the dashboard also helps reduce fogging. Before driving, I check the temperature difference between inside and outside the car to avoid blasting the heater too strongly. Remember, safety always comes first – if fogging becomes severe, slow down and pull over, don't push through, and turn on hazard lights to alert following vehicles. These habits have kept me safe on the road.
I'm usually into tech gadgets, but dealing with foggy car windows requires practical solutions. If the windshield fogs up while driving, I immediately activate the defog mode on the AC system, crank up the fan speed to blow air onto the glass – that automatic dehumidification feature is a lifesaver. For newer cars, it's more convenient to adjust air vents via the center touchscreen; for older models, manually turning on the AC to reduce temperature differences or simply cracking the windows for ventilation works in just 10 seconds. For prevention, I spray anti-fog solution on the windows weekly to prevent moisture buildup. Also, I avoid leaving damp clothes or drinking hot beverages in the car to minimize humidity. While technology is great, these down-to-earth methods ensure clear visibility and safe driving.
