What to use for washer fluid?
A friend of the family had a recipe to make washer fluid. He owned a service station in Minnesota. That was back when they‘d pump gas for you , checked your oil and washed your windows. The stuff didn’t freeze in the winter.
Don’t have the recipe but I found one that I’m sure it close.
Windshield Washer Fluid Recipe
- In a clean 1-gallon jug, combine the water and methanol (if you do not have access to methanol, you can substitute rubbing alcohol), using the proportions listed in the table above.
- For example, if your vehicle will be exposed to temperatures as low as -10 F, choose a mixture of 70% water and 30% methanol. ( you could use cheap vodka too).:D
- Add 1 oz of washer fluid concentrate or dishwashing fluid such as Dawn or Joy.
- Add food coloring if desired. This step is optional and is mainly as a safety feature so that the fluid is not accidentally used for a different purpose.
- Seal the jug and shake lightly to mix (avoid suds). (If it still freezes just add a little more alcohol to it.)
I don’t know of anything that would make it not freeze that wouldn’t mess with the wax.
