If you have tinted windows in your car, it’s important to clean them regularly. This will help keep the window film from becoming dirty and causing the window to fog up. To clean the tinted windows, start by taking off all of the protective film. Then, use a mild soap and water to clean the glass surface. Be sure to use a circular motion, not a sweeping motion, as this will cause more damage to the window film than it will help. Finally, be sure to dry the windows completely before putting them back in place.
