Why Are the Windows Fogging Up?

The windows in your car fog up during the window because of moisture that gets trapped in your car. It gets in from your breath, rain or snow from your shoes, and other sources. 

When the air is at a different temperature than the outside of the windows, then it is on the inside, and the moisture gets close to them, the water clings to the window through condensation. This is condensation, the same thing that happens when you have an ice-cold glass of water in the summer and water accumulates on the outside of the glass. 

You won't be able to escape moisture in your car. It’s constantly cycling through. So the best practice is to keep your car clean and follow these steps to getting rid of foggy windows.

How To Avoid Foggy Windows

Because the moisture in the air of your car is inevitable (unless you stop tracking water in your shoes, breathing, or sweating, which we highly recommend not trying), it’s important to know how to put an end to foggy windows quickly. 

There are a lot of ways to go about this, and you may have had conversations before with friends debating which approach is best. 

Do you use warm air? Cold? Maybe you use the air from the car, or is the outside air best? What should you do with your windows? 

Don’t worry; we’ll answer all of these questions. Foggy windows can slow us down when it gets very cold or very hot, and we deal with it differently depending on the situation.

For When It’s Colder Outside

This is the usual situation. It’s cold and wet outside, and you’ve tracked a bunch of moisture in the night before, and now your windows look like they’ve been painted over. 

Here’s what to do:

  • Use Fresh, Warm Air:

  • Alright, here’s the final word: Use hot air from the outside of your car. Don’t use the circulate function because that will just keep the moisture inside. Instead, blast it away with air from outside. 

    While your car is sucking air in for the air conditioning, it’s also blowing air out, and with it, the moisture that’s causing you to be five minutes later to work than you want to be. 

  • Reduce The Moisture in Your Car:

  • This one might be hard if you live somewhere that rains or snows frequently, but do your best to limit the amount of moisture you bring into the car. 

    Utilize your trunk space if you have any, and make sure to shake off any snow from your jacket or boots before getting in. While you’ll never be 100% moisture-free, this can go a long way in reducing the amount of fog you have to face in the morning. 

  • Crack A Window:

  • We know it’s cold outside, but this is going to help. Cracking your windows while you defrost them helps speed up the amount of time it takes to get rid of the moisture that’s collected. 

    You don’t need to keep them cracked for very long, nor do they have to be all the way open. 

    Just a little bit to help speed up the process. 

  • Clean Your Windows, Inside and Out:

  • First things first: Clean your windows. Yeah, they get a good sheen on the outside when you wash your car using Ultra Concentrated Car Soap Wash, but what about the insides? 

    Using a window cleaner and a clean cloth, clean the inside of all of your windows. 

    The dirt and gunk on the inside of your windows cling to the fog, making it take longer for your defroster to shoo it away. It might take a little time because some of the windows could have some tough to reach spots, but trust us, it’s very much worth it. 

    For When it’s Hotter Outside

    You can still experience foggy windows when it gets hot, but this time the inside of your car is cooler than the outside, so moisture from the air around your car collects on your window. 

    Obviously, you wouldn’t use the same techniques for battling outside fog because the fog isn’t on the inside of the windows, so here’s what to do:

  • Use Your Windshield Wipers:

  • Since the fog has collected on the outside of the windows, using your windshield wipers makes sense, right? While they won’t correct the temperature and moisture level differences, they can expedite the process by wiping away excess moisture from the glass.

    Moisture will still collect while the differences are there but clearing it away as you follow the next steps will make a big difference.


  • Warm Up Your Car:

  • We know, we know, no one wants to turn the heat on when it’s already hot outside. But the reason your windows are accumulating moisture is because of the condensation reaction due to the difference in temperature from the outside to the inside. 

    Turning the heat on a little (or at least turning the AC off altogether, just blowing air) will get your windows’ temperature closer to matching to the outside faster, clearing that pesky fog. 


  • Use Outside Air (Still):

  • This one is the same as when it’s cold; use outside air! Even though the fog is on the outside of the glass this time, your goal is to balance the heat and moisture levels on the glass.

    Using outside air will get there faster. Cracking your window is also not a bad idea, especially if you have the heat turned on in the summer. 

    Tips For Reducing Window Fog

    Whether it’s hot or cold outside, you really want to reduce the amount of fog you have to deal with at all times. 

    Luckily there are plenty of options out there. From cleaners to…shaving cream? Here’s how to deter that pesky moisture from building up on your glass. 

    Use an Anti-Fog Cleaner

    Using an anti-fog cleaning product is a great idea if you seriously want to rid yourself of fog.

    Our Graphene Nano Glass Coating is a top-of-the-line glass projection product that will have water and moisture literally falling off of your windows with the power of graphene.

    Our nano-technology contains particles that are 1/1,000,000,000 the size of a single human hair, each one protecting and deflecting moisture away from your glass. 

    Using this on the outside and inside of your windows will seriously reduce the amount of fog you ever have to deal with since fog is the collection of moisture on the glass. But if the moisture can’t collect on the glass, then you don’t have any fog problems to worry about. 

    Shaving Cream on the Windows?

    Stay calm; this isn’t some classic auto mechanic joke like replacing your blinker fluid. 

    Shaving cream actually contains several of the same chemical components as anti-fogging products. So if you’re in a rush and can't make it to the auto-store (because you can’t see), try applying a very thin layer of shaving cream to your windows. 

    And we want to emphasize that it’s a thin, thin layer. You don’t want to put shaving cream all over your windows because, while you might not have any more fog, you still won't be able to see. 

    If you get too much on the inside or outside of your windows, make sure to clean it off well. Always keep your windows clean using high-quality soap, no matter what time of year it is.


    See Clearly

    Foggy windows can be the bane of a driver's existence in the winter. And when there are already so many other things to worry about during cold conditions like slick roads, it’s important to take care of your car and the things you can control. 

    Never try to drive with just a small patch of de-fogged glass; it’s never worth it to risk your safety. Wait until your windows have completely defogged, and you can confidently see everything in front, to the sides, and behind you. 

    Clean windows don’t just make your car look better (though they definitely do that), but it’s also critical for your safety and the safety of those around you to have clear windows. Make sure to take care of the fog, water spots, and any other spots and scars that’s gotten on them so you can keep riding safely.
