Should temperatures fall even below the freezing point of our economical de-icers and you don’t have a car windscreen frost cover at hand, there’s no need to worry. You can also use a towel, a piece of carpet, cardboard or even a shower curtain to protect your windshield from freezing over.
Another trick is to park in the right direction: Just have your car front window point east – that’s where the sun rises. Especially if you don’t have to head out before sunrise and nothing blocks the sun, you can just let nature do all the work for you.
But what about your side mirrors and windshield wiper blades? Well, place a freezer or plastic bag over your side mirror. Then attach it with a rubber band or clothespins. This way, only the bag will freeze. As for the windshield wiper blades: Wipe them down with a soft cloth soaked in rubbing alcohol (or one of our mentioned mixtures) to keep them from sticking to your windshield.
Finally, if you don’t have special windshield wiper fluid for colder seasons, you can adapt it. Just add five tablespoons of rubbing alcohol to your wiper fluid tank to keep it from freezing inside your car. You could also use this mix as car de-icer. Just activate the wiper fluid and you’ll be clearing your windshield in a cinch.
How to defrost car windows in the morning
Should you be more of a morning person and generally don’t mind clearing the ice on your windscreen on the same day, then you can easily just use your homemade de-icer solutions. But instead of just leaving it on your screen, remove it with a squeegee, a soft-bristled brush or, if the ice is loose enough, use your windshield wipers.
