To quickly de-fog a cold windscreen, use your vehicle’s climate controls to remove moisture from the air inside the cabin and replace it with drier air from outside.
Follow these steps for the fastest results:
Turn on the windscreen defroster
Set the airflow to the windscreen defrost setting.Turn on the air conditioning (A/C)
Even in cold weather, the A/C helps remove moisture from the air and clears the windscreen more effectively.Set the heater to the hottest setting
Warm air can hold more moisture than cold air, which helps clear condensation faster.Turn off air recirculation
Make sure the vehicle is drawing in fresh air from outside rather than recirculating the humid air inside.
Extra tips for clear windows
Crack a window slightly if it’s not raining. This helps let humid air out and brings in drier air from outside.
Avoid wiping the inside of the windscreen with your hand or a cloth, as this can leave streaks and reduce visibility.
