How to Deal with Frost on Car Windows When Using Air Conditioning Inside?

[AlanDella]

The main reason is that the car windows are in contact with the outside, resulting in lower temperatures, which causes the water vapor inside the car to condense on the glass, forming frost. To remove this frost, there are two methods: either increase the temperature of the glass or reduce the humidity inside the car. In fact, many car manuals describe methods for defrosting, such as adjusting the air vents to the windshield setting, turning on the air conditioning, and letting the compressor work to dehumidify. Here are additional tips for preventing frost on car windows: About ten minutes before reaching your destination, turn off the heating. Upon arriving at the parking lot, while organizing items inside the car, roll down all four windows fully. If space permits, opening all four doors can also help, allowing the interior temperature to match the outside temperature before locking the car. This ensures that the windows won’t frost over the next morning; even if frost forms, it will only be a few granular spots rather than covering the entire window.
