If you park outdoors, you know with frigid overnight temperatures the side mirrors of our cars tend to freeze up. You can avoid this by, the night before, slipping a plastic gallon baggie over them and securing with a rubber band. In the morning REMOVE and you won’t have to scrape any ice build up off. If a cold snap catches you off guard, a few drops of rubbing alcohol on the mirrors will do the trick in seconds. Wipe any streaks away.
