How to Prevent Your Car Windows From Fogging
- 1). Clean the inside of your car windows. Dirt and grime on windows provides a layer upon which moisture might settle and accumulate. Use a glass cleaner regularly. Spray and wipe down your windows to remove any dirt and deposits.
- 2). Don't bring wet items inside the car. Moist air is the cause of the fog building up on your windows. Wet umbrellas, snowy boots or sweaty gym clothes can all bring excess moisture into your vehicle's interior. Store damp items in the trunk whenever possible.
- 3). Use the fresh air setting on your vents. This will circulate the moisture in the air and allow it to exit the interior of the car. If you set the car's vents on re-circulate, the moisture has nowhere to go and will remain inside your car.
- 4). Turn on the car's heater and defroster. This step can help to dry out the air, discouraging fog from building up on the windows.
- 5). Roll down the windows and let the moisture escape. This step may not be effective if the outside air is excessively humid or damp. If this is the case, try using the air conditioner or the defroster.
