If you live in a colder climate, be sure to use 99% isopropyl alcohol to prevent the washer fluid from freezing.
Homemade Windshield Washer Fluid Tips
- Use this wiper fluid to clean the rest of the windows in your car or your home.
- It also works great to clean countertops and shine faucets!
- Always remember to label your homemade concoctions.
- The alcohol will keep this from freezing, for stronger anti-freeze protection in severe cold weather, add more alcohol.
- Old gallon jugs from vinegar make the perfect container for storing your homemade windshield formula.
A Note on Car Wax
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.
