What should I do if the outside glass of the car fogs
Reduce the temperature inside the car. The temperature inside the car can be lowered by turning off the warm air function of the air conditioner, opening the Windows, or opening the external circulation air.
Raise the temperature outside the car. The outside temperature can be increased by turning on the windshield wipers or wiping the outside glass with a towel.
Use fog remover. In addition to aerosol can help quickly remove fog on the outside of the car glass.
