How to Deal with Foggy Windows in a Car?
2 Answers
To handle foggy windows in a car, you can follow these methods: 1. Open the windows to create air convection between the inside and outside of the car, which will reduce the temperature difference and make the fog disappear; 2. Turn on the car's defogging function, and select the appropriate cold or warm air from the air conditioner to use the air blown by the air conditioner to defog. The steps to turn on the defogging function are: 1. Open the driver's door; 2. Press the car's brake pedal to start the engine; 3. Press the car's one-touch start button; 4. All the dashboard lights will turn on, indicating that the engine has started; 5. Press the defogging button located on the center console.
I usually drive to and from work. When the windows fog up, the first thing I do is turn on the air conditioning defrost function, adjust the air vents to blow towards the windshield, and turn on the AC switch to cool the air and dry it out. Within a few minutes, the road becomes clear. Fogging mainly occurs when water vapor exhaled by passengers inside the car condenses on the cold glass. In winter, preheating the air conditioning before getting in the car in the morning can prevent this. If it's raining outside and the windows fog up, remember to turn on a bit of the external air circulation to help reduce humidity—don’t rely solely on internal circulation, which can trap moisture. I also keep an anti-fog spray in my car; one application lasts about a week, making it both convenient and safe. Make it a habit to check the temperature difference inside and outside the car. On hot days, open the windows to ventilate and reduce humidity, ensuring fog doesn’t obstruct your vision and endanger your driving.
