Try de icing your car windows with a solution of three parts vinegar to one part water placed in a spray bottle. Simply spray it on all your car windows at night. In the morning, they’ll be clear of an icy mess. How does it do this? Vinegar contains Acetic acid which is a weak organic acid that gives vinegar its distinctive aroma. Vinegar raises the melting point of water which prevents any water from freezing. If you forget to spray on at night and your windows are already frozen try misting the mix on your windows and see it melt way. Magic!
