Not only is a foggy windshield annoying, it is extremely dangerous!

Here are some quick tips to get your window cleared quickly.

Depending on the temperature and the situation you’ll want to attack the condensation on your windshield and windows with different methods.

In chilly weather, the interior of the glass fogs up. The fogging occurs because of the difference in temperature and humidity between the inside of the car and the outside of the car. Outside it’s cold but still generally dry because the air in winter has very low humidity, and inside it’s warmer and more humid thanks to your body heat and the moisture from your breath being trapped inside.

Rapid defog in cold weather

When you need the window defogged right away, the fastest way to do so is to rapidly lower the inside temperature so that the moisture stops condensing on the glass.Turning the defrost vent on without heat or opening the windows in cold weather is the fastest way to dissipate the fog on the window. While fast, it isn’t very comfortable for the occupants of the car so it’s best reserved for times where you find the window suddenly fogging up and you need to see out in a hurry.

It’s significantly more comfortable to use your heater and other methods to manage the moisture. Warming the inside of the car and blowing warm air across the windshield using the defrost setting will evaporate the moisture. Skip using the recirculate feature if your car has it, your goal is to push the humid air out of the car and bring dry air in from the outside.

When It’s HOT outside

In particularly humid weather (a typical North Carolina summer) the opposite problem occurs. High humidity and temperature on the outside of the car and low humidity and temperature on the inside of the car make it necessary to reverse your technique. One option is to use your wipers to constantly clean away the fog from the exterior. The better, less annoying option is to turn the AC down or off entirely, or you can turn the heat on low and warm the inside of the glass to stop the moisture from condensing on the outside.

Other actions to reduce fog

Squeaky clean windows are less prone to fogging and you get the added benefit of better visibility even when they aren’t foggy!

Aquapel treatments to both the inside and outside of the windshield will result in less condensation and fogging to keep you seeing clearly no matter what the weather may be!
