What to Do When the Car Windows Fog Up Inside the Car?

[DeDante]

Solutions for foggy car windows when sitting inside the car include: 1. Use a defogging agent to remove the fog by spraying it evenly on the glass surface and then wiping it clean with a dry towel; 2. Turn on the windshield wipers by setting them to a low speed and let them run until the fog disappears; 3. Change the air source—most cars have a button to either recirculate the air inside the car or draw fresh air from outside; 4. Lower the temperature inside the car. Fog is caused by temperature differences, so matching the interior temperature to the outside temperature can reduce fogging. Increase the car fan setting and lower the temperature as much as possible.
