How to Defog the Windows in Your Car

by techadopters

Cold, humid weather increases the likelihood of your windshield fogging up, and using your sleeve to wipe it away is not the best option. Every car is equipped with a defogger which, as its name implies, was designed to clear fog in a matter of minutes — and, sometimes, in a matter of seconds. Here’s the best way to defog your windows.

Other how-to guides

Turn on the climate control system

Whether it’s in the dead of winter when it’s cold outside or in the middle of the summer when it’s scorching hot, your car’s climate control system does more than just regulate the cabin temperature. It doubles as a dehumidifier. On most newer cars, the easiest way to clear fog is to simply press the button with the defogger icon (shown below).

The defogger normally sets the blower fan to its highest setting. As long as your car’s climate control system is functioning properly, your windows should be clear of fog in no time. Turn it off as soon as you can see.

What if your car’s climate control system is malfunctioning?

We totally understand; climate control-related repairs get costly really quickly. If air no longer comes out of the vents, or if it’s not warm enough to clear the fog, we recommend keeping a roll of paper towels, napkins, or a set of clean rags inside your car within easy reach. That way you’ll avoid using your hands or sleeves to clear condensation, and you won’t leave marks on the windshield. It’s much wiser to do this when you’re parked.

Alternatively, the tried-and-true solution of cracking a window works, though you’ll freeze until you can see.

And the best way to keep your windows from fogging up?

A simple window cleaner product such as Windex should keep your windows clean and clear. Keep in mind it will leave behind an unpleasant residue if not wiped off properly. This leads to a multitude of problems such as smears and streaks when the windows fog up, making them even more challenging to clean and see-through.

One option is to use a dedicated car window cleaner, such as Rain-X or Invisible Glass window cleaner. These products are specifically designed not to leave streaks. What’s more, is they aren’t difficult to obtain. Whether you shop in stores or online, these products are available in abundance. Let’s not forget that they are also inexpensive. It’s hard to ignore an offer of a total package such as this one.

If you want to rest assured that a product will provide you with clean, clear windows, we recommend using Rain-X glass cleaner and water repellent treatment. This treatment effectively inhibits the formation of condensation on glass by covering it in a translucent sheen.

When you neglect fog buildup on your windows, you are putting your life in danger. Knowing how to combat the results of mixing frigid exterior weather with your car’s warm interior environment can save your life. These tips will keep you safe and out of harm’s way.
