To make your own all-natural window cleaner, combine equal parts white vinegar and water in a spray bottle, as recommended by Erin Huffstetler of About.com. Homemade vinegar-based glass cleaner is inexpensive, removes fingerprints and does not leave streaks.
When making your own natural window cleaner, always buy a new bottle instead of reusing one from store-bought glass cleaner, advises Huffstetler. Be sure to label the cleaner and keep it where children and pets cannot reach it. You can use homemade glass cleaner just as you would a conventional glass cleaner from the store. It does not contain any harsh chemicals or emit harmful fumes. It is free from ammonia, which is found in many glass cleaners and is poisonous when inhaled or ingested.
A mixture of high-proof alcohol, white vinegar, liquid soap and water can also be used as a natural window cleaner, according to DIY Natural's Betsy Jabs. The recommended amounts are 1 cup high-proof alcohol, such as Everclear vodka, 1/4 cup white vinegar, 1/2 teaspoon liquid soap and enough water to make 1/2 gallon of cleaner. The liquid soap is optional, but castile soap should not be used. To use the cleaner, spray it on windows, mirrors or countertops, and then wipe it off with a soft cloth.
