Homemade windshield washer fluid is easy to make, inexpensive, and all-natural. Ditch the commercial stuff, save money, and make your own!
Pour the rubbing alcohol into the empty jug then fill the jug with water, leaving room for the soap.
Slowly add the soap and optional food coloring to the jug.
Cap the jug and gently tip upside down a few times to mix ingredients.
Pour windshield wiper fluid into the correct compartment under your car hood.
If you live in a colder climate, be sure to use 99% isopropyl alcohol to prevent the washer fluid from freezing.
Isopropyl (rubbing) alcohol is used to remove car wax at a ratio of 1:1 (1 part water to 1 part alcohol). This homemade windshield washer fluid calls for a dilution of 16:1 (and 8:1 in extreme cold), so it should not have any effects on the wax. That said, we recommend testing this on a small area before pouring solution in washer reservoir and using.
