Fog is a problem in the winter months. Condensation occurs when cold air from outside touches windows heated inside the car. Visibility can be significantly reduced by fog. It can also be annoying if you are trying to get somewhere fast.
There are four steps to get rid of fog from windshields and car windows.
- Turn up the heat.
- Turn on the A/C.
- Deactivate the air circulation.
- Turn down the car’s windows.
Learn the science behind car window fogging and how to defog your vehicle. We also have some tips to prevent fog from forming on your auto glass in the future.
Why are my car windows fogged up?
Low relative humidity points are a sign of cold winter weather. Cooler air holds more moisture than warmer interior environments. Wet jackets and snow on your shoes can increase humidity. As they drive, the occupants inhale hot and humid air. They might have a cup of coffee on their morning commutes to help them inhale the steam. The fog on the windshield or windows can cause visibility problems as the car heats up.
How can I defog my windows?
You can defog your vehicle’s glass quickly by following these four steps. These DIY tips are supported by science.
Heat up!
This action is the first thing you should do. Turn the heat up to full blast when you get into your car. The car will absorb more moisture if heated to the maximum setting.
Turn on the air conditioning
Next, turn on the air conditioner. Although it may appear that it will make foggy windows worsen, it absorbs excess moisture.
Turn off air recirculation
Turn off the air-recirculation option to clear the windows. You can deactivate this climate control feature by pressing the button with a curving arrow inside a car symbol. It is best to bring in cold air from outside to accelerate the process of eliminating moisture. In addition, because the car’s interior is more sensitive to temperature variations, the colder winter air won’t retain as much moisture.
Crack open windows
Last, open the side windows a little. Although it might feel uncomfortable and cold for the driver and passengers, it is only temporary. It would be best to open as many windows as possible to defrost your windshield quickly. This action will replace the humid air in your car with dry outside air.
