How to Deal with Car Fogging?
2 Answers
Solutions for car fogging: 1. Open the windows: Fogging inside the car is caused by the temperature difference between the inside and outside. Opening the windows for ventilation will naturally dissipate the fog in a short time; 2. Turn on the air conditioner first, then switch to the heater after the fog clears: Cars come with a defogging function. Turning on the air conditioner quickly lowers the temperature of the front windshield, preventing fog from condensing, while the heater ensures the driver doesn't feel cold; 3. Wipe with a cloth: Many drivers commonly use this method while driving—wiping the fog off the windshield with a cloth to maintain clear visibility; 4. Use a defogging agent: Dilute dish soap with water in a 1:6 ratio, then apply it evenly to the windows with a cloth or spray bottle. Once dry, wipe it off with a towel.
I've encountered car window fogging quite a few times, mainly when there's a big temperature difference or during rainy drives. When dealing with it, I always start by turning on the air conditioning defogging mode first. Pressing that button directs cold air toward the windshield, usually clearing the view within two or three minutes. If I don't want to use the AC, I'll crack open the front windows slightly for ventilation, or switch to external air circulation mode to let fresh air in and dilute the humidity inside. If the fog clears too slowly, try setting the AC temperature to medium—not too hot nor too cold—while turning the fan to maximum speed. Remember not to leave damp items like umbrellas or shoes in the car, as they increase humidity. During regular maintenance, I also clean the interior glass periodically with a slightly damp cloth to remove oily films, making it harder for fog to form. Safety comes first—if fogging becomes severe, always pull over to handle it instead of driving distracted. Oh, and anti-fog sprays work well too; after applying, gently wipe with a towel, and the effect can last several days fog-free.
