There’s so much to love about autumn! The colorful leaves, the pumpkins, the comforts of home! But, of course, there are some down sides, too. Along with fewer hours of sunlight, autumn brings dropping temperatures. Sometimes, from year to year, we all forget exactly what we do to drive safely once those colder temps hit. One of the safety issues that can arise during the autumn months is foggy windows.
What Causes Foggy Windows
Often, it’s not the actual temperatures that cause the fog; it’s the disparity between the temperature inside your vehicle and the outdoor temperature. Now, we’re not saying you shouldn’t turn on the heat, of course! But be aware that doing so will cause your car’s windows to fog up. Technically, the issue isn’t due to the disparity of temperature, but the resulting moisture content in the air.
The inside of your vehicle has plenty of moisture in the air. (Think of snowy boots and just the moisture on your breath.) That moisture turns into liquid when it hits a window that’s below the dew point. That resulting condensation makes your windows appear foggy.
How To Clear Foggy Windows
As fog begins to form inside your car’s windows, one way you can respond is to lower your vehicle’s inside temperature. You can quickly and easily do this by either cracking a window or turning on your car’s defrost, set to cool. The reduced disparity between indoor and outdoor temperature and moisture content will promote a decrease in the fogginess. You can also turn on the rear defrost for help in clearing up the back window. Of course, there’s a down side to this method — namely, you’re going to be pretty cold!
A more comfortable way to deal with foggy windows is to turn on your vehicle’s defrost, blowing warm air onto the windshield. The moisture will evaporate. (Be sure the recirculate feature, the one with arrows going in a circle, has been turned off, so your vehicle isn’t reusing air inside your car. You want to make sure it’s constantly taking in the dry air from outside, instead.
How To Notice and Prevent Foggy Windows
One issue some car owners have is that they’re never sure when their windows are foggy or just plain dirty. No matter how much you run your vehicle’s defrost, it won’t clean your windshield! Among the many reasons to keep your windshield clean is that you’ll be able to more easily tell when fog is forming.
In addition to typical cleaning, you may want to spray or wipe a product such as Interior Glass Anti-Fog products made by Rain-X® on the inside of your windows, which will prevent fog from forming at all.
