Put on some winter gloves
Frostbite takes anywhere from two to 30 minutes to hit, depending on the severity of the weather. Keep yourself comfortable (and safe) while de-icing your car by putting on your winter gloves before you begin.
Brush off the snow covering the ice
Before you start chipping away at the ice, remove the snow resting on top of it, if any. Use a snow brush or your gloved hands to brush it away.
Smack the hood gently with the flat of your hand
This breaks the ice on your car into large pieces, making them easier to remove and melt. It’s another reason to wear gloves while de-icing your vehicle!
Start the car and turn on the headlights
Let the car heat up so the temperature can gradually melt the ice — but make sure you’ve cleared the exhaust pipe and the radiator grill before doing so. Plus, turn on the headlights, so the heat will make it easier to scrape the ice off the lenses.
Purchase a commercial de-icing spray
If you’re looking for a quick solution that won’t destroy your windshield, you can grab a commercial de-icing spray from stores like Wal-Mart or Canadian Tire. Keep them in your garage or at your office, and simply spray it over your windshield or doors to defrost your vehicle in a matter of minutes. These mixtures can cost anywhere from $10 to over $20, depending on the brand.
If you’re expecting sub-zero temperatures and precipitation, you can even apply some spray the night before to make it a little easier for yourself in the morning.
Whatever you do, don’t pour boiling water on your windshield. The sudden spike in temperature can cause your windshield to crack.
