Vinegar is great for a lot of things around the house -- it's been an ingredient in homemade cleaning solutions for years. You can use vinegar for on your car, too! Mix together 1 cup white vinegar with 2 cups water and put it in a misting bottle. Spritz your car windows during the winter -- the mixture will melt the frost or ice from your windows and prevent more ice from forming on the glass. If you have ice build-up in your windshield wipers, you can spray them, too.
