Morning are hectic — we get it! Sometimes it feels like there aren't enough hours in the a.m. to make sure the kids are up, washed, and fed before you scarf down your breakfast and leave for work. The last thing you want to wait for is the windows to defog. And now you don't have to, because we've discovered the best — if not unexpected — way to defog car windows.
Defog Your Car Windows With Cat Litter
It's super weird, but it's true! And it makes sense if you think about it: Just as the litter absorbs moisture in your cat's litter box, so too will it suck up extra moisture in your car, preventing fog from even forming on your windows. But before you scatter a bunch of litter all over your dashboard (can you say "cleaning nightmare"?) — follow this simple but important tip: Take one of those old socks that lost its mate long, long ago but you've been saving it in the hopes the other sock magically reappears (it's not coming back, face it) and fill it with a cup or two of cat litter. (Make sure there aren't any holes in the sock or you're going to be facing aforementioned cleaning nightmare!) Tie the top of the sock closed and place the "litter sachet", if you will, on your dashboard. Voila! Buh-bye, poor visibility!
How to Defog Car Windows Fast Using Car Controls
Most cars have a handy defog/defrost button that you can press these days, but if you're one of the few drivers who doesn't have one, you might wonder what combination of button pressing will defog your windows the quickest. Do you blast the cool air or crank up the heat? Should you turn on the AC or use recirculated air? Does cracking the windows help at all?
According to former NASA engineer Mark Rober, the best way to defog car windows fast is to follow these steps:
1. Turn your defroster fan to the highest setting.
2. Crank the temperature control to the hottest setting.
3. Turn on your AC.
4. Turn off recirculation.
5. Open your windows a bit.

How to Defog Car Windows Without Heat (and Kitty Litter)
Don't have heat but need to clear your foggy car windows fast? There are a few options when it comes to defogging car windows without heat:
Window Anti-Fog Treatment: If you don't want to worry about fog or frost on your windshield or windows, try a window anti-fog treatment ($14.90, Amazon). Coating all the surfaces you want to keep fog- and frost-free will take a little bit of elbow grease, but it'll save you a few extra minutes every morning.
Shaving Cream Anti-Fog Treatment: A cheaper anti-fog window treatment option is good old-fashioned shaving cream. Cleaning your windows with shaving cream creates a thin layer that keeps the glass from fogging. Neat, huh?
Silica Gel Dehumidifier: Similar to kitty litter, silica gel dehumidifiers remove excess moisture. You can purchase a silica gel dehumidifier ($7.99, Amazon) for less than $10, but if you've been saving the small silica packets that come in shoe boxes and cured meats packages, you can just use those and don't need to spend a dime!
