There are a few things you can do to prevent foggy windows on your car. First, make sure your car has a good sealant on the glass. Second, use a clear film or plastic window film to keep the inside of your car clear. Third, use a windshield wiper to clean the glass every time you drive. Finally, be sure to keep your windows clean and dry when not in use by using a window cleaner and/or air freshener.
