How to Remove Fog from Car Windows in Summer?

Methods to remove fog from car windows in summer include: 1. Wipe it clean with a cloth; 2. Use specialized defogging products by evenly spraying the defogger on the surface of the car window glass and wiping it clean with a dry towel; 3. Turn on the front window defogging mode, set the fan speed to maximum, turn on the AC switch, and then adjust the temperature to the lowest setting; 4. Use dishwashing liquid, soap, etc., which can be applied to car windows for anti-fogging purposes. These detergents can disrupt the attraction between water molecules, reducing their surface tension and causing water molecules to distribute evenly on the treated glass surface, forming a water film. The more rainwater on the glass, the larger the water film becomes, ensuring the car windows remain clear and maintain good visibility.

Having driven for decades, I'm most skilled at handling foggy car windows in summer. The reason is simple: in hot and humid weather, the car's air conditioning cools the glass, causing the hot outside air to condense into fog. The solution: immediately turn on the air conditioning's defogging function, set the windshield vents to maximum airflow, as cold air removes fog quickly; if not using air conditioning, slightly open the windows to allow air circulation and balance the temperature difference. For prevention, I always recommend using a sunshade when parked to reduce heat buildup; avoid leaving wet clothes or water cups inside the car. Safety first—when fogging occurs, I prefer to slow down and pull over to deal with it. Wiping the glass with soapy water is also effective, but needs to be done frequently. Regular maintenance of the air conditioning filter is fundamental to preventing fogging, a point I always emphasize at car club meetings to avoid accidents caused by driving in foggy conditions.

My new car has an intelligent defogging function, so I don’t worry at all about foggy windows in summer. Once fog is detected, I press the AUTO button to adjust the AC to blow on the windshield, and the cold air automatically dehumidifies. Don’t have this feature? Just open the windows for two minutes to let the air circulate. For prevention, I use the app to remotely start the ventilation fan for pre-cooling. Try applying soapy water to the inside of the glass or use an anti-fog spray, but minimize chemical usage. In summer, don’t keep the windows closed and stuffy—hot air entering the car can easily cause fogging, so crack the windows slightly before getting in. As a tech enthusiast, I pay attention to air sensors that detect humidity. Safety is the top priority when defogging—set the fan to medium speed to avoid affecting driving.

When traveling with children in summer and the windshield fogs up, I handle it immediately with safety first. Turn on the AC to blow the windshield or use a clean cloth to wipe off the fog. Simply opening the windows can also help, but not too wide to avoid noise. High humidity inside the car easily causes fogging, so avoid placing water bottles or towels. I DIY a vinegar-water spray for the glass, which is economical and eco-friendly. Prevention method: In summer, open the car doors in advance for ventilation, and don’t set the AC temperature too low. The key is to maintain clear visibility and handle the situation at a slow speed for safety.
