Prevent frosted car windows in the interior
Often the car windows are also iced in the morning. The reason is the moist air that condenses and freezes overnight in the car on the cold slices. Warm air stores a lot of moisture, which means that if you are heating hard you have a lot of moisture in the car.
My tip: shortly before the car is turned off, open all windows and replace the warm moist air with cool, dry air (the same principle as with mildew in the apartment). Of course it does not help if the water runs along the window while driving.
