How to Solve Fogging on Car Windows?
3 Answers
Turn the air conditioning temperature adjustment button to the warm air direction, press the defrost button, and use the warm air generated by the air conditioning to dry the fog on the windshield. If the fog is not heavy, you can open a small gap in the windows on both sides to allow air convection inside the car. You can use the wipers directly, but remember to spray water while wiping, not dry wiping. Turn on the air conditioning and direct it to blow onto the front windshield.
I'm all too familiar with the issue of foggy car windows. Driving my kids to school in winter, I face it every day. My go-to method is to immediately turn on the air conditioning, rotate the temperature knob to the warm air setting, crank the fan to maximum, and press the defrost button—the fog usually clears within a minute or two. On humid summer days, I turn on the AC along with the external air circulation, which works like a charm. Here's a handy tip: wiping the inside of the windows with a diluted soap or detergent solution beforehand can keep them fog-free for several days. Also, remember not to leave wet umbrellas in the car when parked, and cracking the windows slightly for ventilation is crucial. These habits can effectively prevent fog from obstructing your view.
The most annoying thing when driving to work on rainy days is the fogging up of the windshield. My quick solution is divided into three steps: first, adjust the air conditioning to the windshield defogging mode, turn the fan to maximum, then turn on the external circulation and AC cooling, and set the temperature to around 22 degrees. It usually clears up in about 30 seconds. If the fog is severe, immediately pull over and wipe the inside with a dry towel—safety first. I usually keep a bottle of professional defogging spray in the glove compartment, and spraying it once a month is enough. A special reminder for friends with automatic air conditioning: pressing the front windshield defogging button directly is the easiest, as the system will automatically adjust the fan speed and temperature.
