How to Deal with Fog on the Windshield on Rainy Days?
2 Answers
Solutions for fog on the windshield on rainy days: 1. Turn on the heater and increase the fan speed. The dry, warm air will evaporate the water molecules in the car's interior air, preventing fog from forming on the windshield. 2. If the rain is not heavy, you can simply open the windows for a few seconds to clear the fog. This works by lowering the interior temperature, making it harder for moisture to condense. 3. Turn on the defroster in the car, which blows dry, cold air onto the windshield from the inside. This evens out the temperature on both sides of the glass, creating a dry air barrier that prevents the moist air inside the car from condensing and forming fog.
The most annoying thing about driving in the rain is when the windshield fogs up, making it impossible to see the road clearly, which can be incredibly frustrating. If fog suddenly appears, don’t panic. Quickly turn on the air conditioning and set it to the windshield defogging mode, while also activating the external circulation with cold air. Usually, it takes just half a minute to clear up. This method works well in both winter and summer, as cold air removes fog quickly and efficiently. For prevention, you can buy an anti-fog spray to apply on the inside of the windshield—a bottle from the supermarket for around ten yuan will last two to three days. If you’re in a real hurry, you can temporarily wipe it with a dry cloth, but never do this while driving—pull over safely first. Also, remember to regularly replace the dehumidifier box in your car, especially in areas with frequent rain during the rainy season, as high humidity makes fogging more likely.
