What is the recommended method for defogging a front windshield?

The recommended method for defogging a front windshield involves turning on the defogger and air conditioner. This approach is effective because the air conditioner helps dehumidify the air inside the vehicle, which in turn reduces the moisture that causes fogging on the glass. When the defogger is activated, it directs airflow towards the windshield, ensuring that the dry air from the air conditioner reaches the surface of the glass to clear it quickly.

Using this method is particularly beneficial because it combines temperature control with moisture removal. The air conditioning system, by cooling the air, can carry away moisture more efficiently than simply relying on the vehicle's heating system.

In contrast, options such as opening the windows may not fully address the humidity inside the vehicle and can introduce additional moisture from outside, especially in humid conditions. Using a towel to wipe the windshield can be a temporary fix but does not address the underlying moisture problem and can end up redistributing any remaining condensation. Turning on the heat could help in a dry environment but does not effectively remove humidity, which is the primary cause of fogging.
