What are the methods to defog a car?

[StNathan]

If the fog is not heavy, you can open a small gap in the side windows to allow air convection inside the car, which will help dissipate the fog. Use the air conditioner's cold or warm air, combined with the defog button, to achieve the defogging effect. During rainy weather, you can turn on the car's air conditioner and set it to cold air to quickly remove the fog. Turn on the car's warm air conditioner to dry the interior fog with the hot air. This is the most primitive method—use a dry cloth to wipe the glass.
