How to Remove Fog from the Car?

[RobertMarie]

Methods to remove fog from the car include: 1. Turn on the air conditioner's heating mode and direct the airflow toward the windows to reduce the temperature difference between the inside and outside of the glass, thereby eliminating fog; 2. Open the windows slightly to create air convection, which helps remove moisture and reduces water condensation on the glass, balancing the interior and exterior temperatures; 3. Use a defogging spray. If unavailable, alternatives like dish soap, soapy water, or saltwater can be used. Fog forms on the car windows because the warm, humid air inside the cabin condenses on the cooler windshield when the air conditioner is on.
