How Do You Make Windshield Washer Fluid?
Several combinations of common household items will clean windows. If there’s no risk of freezing there are several cost effective ways to make windshield washer fluid. Some freeze resistant mixtures are great for windows, but harmful to rubber hoses and pump parts. To make windshield washer fluid that doesn’t freeze or eat rubber is more expensive than buying a gallon from a store. Yet if necessity outweighs cost, it can be done. Pour 3 cups of water into a 2 quart bottle. Distilled water is better for the system than tap water. Add a touch of liquid dish soap–use no more than a teaspoon of dishwashing liquid. Any brand will do. Add 1 cup of ammonia. Cap the bottle and gently rotate to stir. Keep it from freezing. Add 1 cup of undiluted antifreeze or methanol. If freezing is not a consideration, simply add another cup of water. Stir gently as in step 3.
