It’s not an uncommon scenario. Imagine you’re already late, you’ve spent a few minutes clearing snow off your car, and you attempt to roll down your window so you can see better to back up. Nothing. Welcome to winter, and a frozen car window.
Well-functioning, clear car windows can improve visibility and even serve as a way out of your vehicle in the event of an accident. A frozen car window can impede your peripheral vision and make winter driving more dangerous.
Luckily, there’s a quick and easy fix to unfreeze car windows and get you back on the road safely.
How to Unfreeze Car Windows Fast
If you are one of the many people who find your car window frozen shut during cold temperatures, isopropyl alcohol can be used to create a simple DIY de-icing solution.
DIY De-icer for Car Windows
To de-ice car windows fast, make a simple DIY window de-icing solution. You’ll need:
- ¾ cup of isopropyl alcohol (available at any grocery or pharmacy)
- ¼ cup of water (room temperature)
- Spray bottle
Spray, Wait, and Scrape
To unfreeze car windows, simply add the alcohol and water to the spray bottle and shake. Then, spray the solution on the frozen window close to the bottom. The ice freezing your window shut will slowly melt, including any ice inside your door.
Be patient and allow the mixture 2-3 minutes before gently using your ice scraper to remove the slushy ice. This works for windshields, too.
Do not attempt to roll down the window until you’ve successfully cleared the ice, and never force a frozen car window.
While it’s tempting to keep pressing the button to force the window down, this can damage the motor housed inside your car door. Always use your ice scraper and the isopropyl alcohol method to reduce the risk of damaging your window or the motor.
How to Avoid Frozen Car Windows
When your car window is frozen shut, it’s a major inconvenience. Since car owners can’t do much about the weather, you can reduce the risk of frozen windows by:
- Parking undercover. Keep your car parked in the garage during the winter. If you don’t have one, even parking under a tree can reduce the amount of snow and ice accumulating on your car. If that isn’t an option, try to park in a spot protected from wind.
- Use a windshield cover. Windshield covers are a fantastic way to reduce the amount of snow and ice that builds up on your windshield.
- Control humidity. If you notice ice building up on the inside of your car’s windows, it’s likely due to humidity in the cabin. Avoid adding moisture to your interior by removing ice and snow from your boots and coat before you enter the vehicle.
What If My Car Window Won’t Open Once Defrosted?
After your window is defrosted, it should open and close normally. If your window is still stuck, the power window regulator has likely been damaged. There are two types of power window regulators popular in motor vehicles today: cable-type and gear-drive. At Glass Doctor®, we replace both types of power window regulators.

How to unfreeze car windows the fastest?
While prevention is key, sometimes you need a quick solution. Using a de-icer spray (see the DIY solution listed above) or a scraper designed for car windows can help you quickly remove ice. Remember to be gentle and patient as the window de-ices to avoid damaging your windows.
Can I use hot water to de-ice car windows fast?
We strongly advise against using hot water to melt ice on your car windows. The sudden temperature change can cause your windows to crack or shatter. Opt for a gradual thawing method using a simple DIY or commercial de-icer spray instead.
How do I prevent my car windows from freezing shut?
Preventing frozen windows is the best approach! You can cover your car windows with a tarp, towel, or windshield cover overnight, park in a garage if possible, or apply a specialized window treatment that prevents ice from forming, which is available in most major retailers (Walmart, Target) or auto parts stores like AutoZone or NAPA.
Can vinegar or alcohol help to unfreeze car windows?
Yes, a mixture of vinegar and water or rubbing alcohol and water can help to defrost your car windows. These solutions lower the freezing point of water, making it harder for ice to form. However, it's still important to apply them carefully and de-ice slowly. Always avoid pouring them directly onto very cold glass, and never use hot water to attempt to de-ice car windows fast.
