How to Deal with Fog on the Outside of the Windshield?
3 Answers
Methods to deal with fog on the outside of the windshield: 1. Use the car's built-in air conditioning system by turning on the fan and cooling switch. The cold air will disperse the fog on the windshield. Besides using air conditioning for defogging, hot air can also serve the same purpose; 2. Open the windows to allow convection of cold and hot air. Crack the side windows slightly to facilitate air convection inside the car. As the interior temperature gradually matches the outside temperature, the fog will dissipate; 3. Use specialized anti-fog products. Spray evenly on the windows and wipe clean before use to form a transparent protective film on the glass, preventing fog formation. One application can last for half a month; 4. Use dish soap with a dry cloth. Mix dish soap with water at a ratio of 1:6, apply evenly on the car glass with a sponge, and wipe clean with a car towel after drying. This method leaves no watermarks and can effectively prevent fog for up to 20 hours.
When the windshield fogs up outside while driving, I find it quite annoying, but it's quite common in humid or cold weather. I immediately turn on the wipers to clear it, and they wipe it clean in an instant. The condition of the wiper blades is crucial, so it's important to replace old ones regularly. If the fogging persists after using the wipers, I switch the air conditioning to defrost mode, increase the airflow, and direct it toward the glass. This quickly dries out the moisture and keeps the view clear. For safety, never wait too long because fogged-up windows can impair driving vision and easily lead to accidents. I make it a habit to check the windshield washer fluid level in advance and avoid setting the car heater too high to reduce temperature differences. Paying attention to air circulation, such as opening the windows briefly for ventilation, can also prevent fog buildup.
To address the issue of fogging on the outside of the glass, I prefer using energy-saving methods, which are both cost-effective and environmentally friendly. Fogging is mostly caused by the contact between cold glass and warm, humid air. Instead of using the air conditioner at high power to dehumidify, I first lightly press the wiper to remove moisture. If the fogging persists, I then turn on the air conditioner and set a balanced temperature, such as cold air in summer or warm air in winter, while lowering the fan speed. For prevention, I leave a small gap for ventilation when parking to reduce humidity inside the car. I also use the wiper with clean water to wipe the glass, avoiding chemical sprays that can cause pollution. This ensures driving safety while reducing carbon emissions, as energy conservation is beneficial for the planet. When visibility is poor, I carefully slow down.
