The science behind a foggy car window is actually quite simple. When there is a difference between the outside and interior air temperature, moisture gets deposited on your car windows. That’s why during winter months when the temperature drops, you’ll notice more condensation on the inside of your car. Conversely, when it’s hot and humid outside and you put on the air conditioner, you’ll notice that the exterior windows fog up. Annoying? Yes. But thankfully there are ways to combat it and get your windows back in the clear.
Put the Wet Stuff in the Trunk
Sweaty Gym Clothes. Umbrellas. Ski Boots. What do all of these items have in common? They carry a lot of moisture with them that will make your car windows fog up. If possible, put these items in the trunk before driving. Also, if you’re coming into your car from the snow, give your feet a few claps together before entering the vehicle to clear away any excess.
Keep Your Car Mats Dry
Another culprit to foggy windows are your car mats. Inevitably they will get wet during rainy days, but do your best to limit the amount of moisture they take in. This is especially true if you’ve recently detailed or cleaned your car. If there is any residual water or chemical formula on the mats still you may encounter a bit of fogging as they dry out inside your vehicle.
Keep Your Windows Cleaned and Protected
Contaminants such as streaks, smudges and dirt give moisture droplets an easier base to settle on. Make sure you keep your glass
cleaned and protected to minimize fogging. Car window cleaning products come in many different varieties. Try selecting one such as Eco Touch window clear which is free of ammonia or alcohol. Next, add a layer of protection which will help keep moisture from settling on the surface. We suggest Eco Touch Quick Wax since it safe for all glass and window surfaces. Use sparingly and buff with a dry microfiber towel for best results.
