Tips to quickly clear your windows of condensation
You're making your way home in the chilly rain, and suddenly you can't see out of the windows of your trusty sedan. Your car's windscreen and windows fogging up can be frustrating as it impacts your ability to see the road. So how do you defog your windshield? In this discussion, we look at what causes fogging up on the windows, and how to deal with this common problem.
A few things to know about window fog and what causes the inside of your car to become misty:
So, now that you know what causes condensation on the inside of car windows, here's how to defog your windshield and windows when it does happen.
During the winter season or perhaps when you are driving in icy rain, you'll notice fog the windows. Often in bigger cars, say a Chevy Suburban, this happens at the front of the vehicle where the passengers are sitting, and smaller vehicles like hatchbacks often fog up quicker all around. The best way to clear these foggy car windows is with a steady supply of dry, hot air. Activate your car's air conditioning and turn up the heat, once the temperature from the AC has increased, select the windscreen vents, and watch the magic happen. Cold, fresh air will actually have the same effect, so if you don't have a working AC, crack a window and set your vents to circulate air from the outside instead of recirculating cabin air, this will diminish the humidity within the cabin and clear up the windows.
Wiping the windows down with a dry cloth or your sleeve isn't very effective as you'll likely just gather the moisture that's there and spread it around. Plus, because the temperature in the car wouldn't have changed, the condensation will just reoccur. Your breathing will also simply counter the efforts.
There are several ways to prevent the windows of your car from fogging up:
A foggy windshield can be a serious safety hazard during driving, which is why knowing how to get rid of fog on your windshield quickly is so important. Fortunately, by using one or all of these very simple tips provided, condensation forming on the inside of your car's windows should be easily dealt with.
Both will work as well as the other - what stops the condensation is the constant flow of air onto the windows which also dries the moisture from the air. This is why it's good to make use of the AC, instead of naturally occurring air which may already be quite moist and humid.
Defogging is the process of eliminating fog usually from the inside of the vehicle, while defrosting is the process of eliminating frozen moisture usually from the outside of the vehicle. The term defrosting also implies the occurrence of ice or frost, which will need to be removed.
An anti-fog treatment or water-repellent coating is the most effective treatment for preventing your windscreen and windows from fogging up. There are multiple brands that can be found at most retailers at very affordable prices.
When you climb into your car on a cold winter's day, you start to warm up the air in the cabin with your breath and body heat, and that air then holds the moisture. This results in condensation on the inside windows of the car as the air on the outside is still very cold.
