If you live in a place where it snows for three or more months out of the year, you know that defrosting car windows is not just a slight inconvenience; it can become a time-consuming part of your morning routine.
Growing up in the Midwest, I know all of the tricks: turn your car on ten minutes before you plan on leaving, expensive defrost spray, buy one of those strange pairs of gloves that has an ice scraper built in. No one method is foolproof nor anywhere near seamless. But Weathers has a homemade solution that will only take you a minute to make—you probably already have the necessary ingredients—and will make defrosting your windows as easy as taking a lap around your car.
Mix two-third parts of rubbing alcohol with one-third part of water. Put it in a spray bottle, and you’re set for the worst of winter months.
