How to Deal with Fogging on the Outside of Car Windows in Autumn?
3 Answers
Simply turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and then adjust the temperature to the lowest setting to eliminate fogging. Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation. This method is very economical. When using, just spray it evenly on the glass surface and then wipe it clean with a dry towel.
I've been driving for over a decade, and foggy windows on autumn mornings are extremely common, mainly due to high humidity and rapid temperature changes. First, don't panic—immediately turn on the wipers for a gentle sweep, which usually clears most of the fog. If that doesn’t work, quickly start the car’s air conditioning, switch to the windshield defrost mode, and add some warm air to dehumidify. I always keep a bottle of window defogging spray handy—a quick spray and wipe works wonders. For prevention, regular car washes to remove oil film buildup on the glass are crucial, especially in autumn when frequent rain leads to dirt accumulation. I use a specialized cleaner every time I wash my car. Also, avoid parking in damp areas, and use moisture absorbers or crack the windows slightly to reduce humidity inside. While foggy windows are annoying, timely action prevents any real trouble—just don’t drive blindly to avoid accidents.
As a parent, my biggest concern in autumn is the fogged-up windows affecting visibility when driving my kids to school. The damp and cold weather can easily disrupt driving safety. My solution is to first use the wipers to clear the outer layer of fog, then turn on the windshield defogging function of the AC to blow hot air and quickly dry the glass. I usually teach my family to maintain air circulation inside the car, such as using the external air circulation to reduce the risk of fogging due to temperature differences. If the wipers aren’t strong enough, keeping a microfiber cloth handy for wiping is also very effective. I also recommend washing the car windows frequently in autumn to remove fingerprints or residues and prevent fogging. Handling these small things well makes driving more reassuring, especially when taking the kids out, as it helps avoid panic.
