To make a glass cleaner, mix together 1 cup of water, 1/4 cup of white distilled vinegar and 1/2 teaspoon of organic dishwashing liquid. Pour mixture into a spray bottle and shake it up. Use this solution on all your windows.
Vinegar and water alone leaves streaks the dish liquid is what helps cut the waxy buildup that glass develops, says green guru Annie Bond. In place of vinegar, you can substitute undiluted lemon juice or club soda.
