Defogging your windshield can be tricky, especially in colder temperatures. That’s why we’ve put together a post on the most effective methods, helping you to get on the road as quick as possible. Plus, proper defogging ensures you have the best visibility possible. Don’t drive with your head sticking outside of your window—follow these tips.
Windows fog up because of the process of condensation. This is the same process that causes dew to be found on grass in the morning or the moisture on the outside of a can. Condensation is caused by humidity—the amount of moisture in the air—and it can be eliminated by following some simple steps.
The most effective method is to start by turning up your heater all the way. This will work to absorb moisture. Next, turn your air conditioning on. This pulls moisture out of the air as it passes through the A/C system. It’s important at this point to make sure that the air circulation is turned off—you only want cold, dry air from the outside of the vehicle. Finally, crack your windows to allow as much cool, dry air to enter your car.
In addition to this process, you can also try some other tips. Fill a sock with cat litter and place it in your windshield overnight. This absorbs moisture and prevents condensation from forming on your windshield. You can also use shaving cream (like Barbasol), which has a unique set of chemicals to prevents moisture buildup.
