I go through a lot of windshield washer fluid in the winter and spring. I never thought of trying to make a DIY version. But Jill of One Good Thing by Jillee did!
It is a surprisingly easy recipe with just 4 ingredients. They are common, household ingredients too. The other advantage is that the natural version doesn’t contain the methanol which is present in commercial windshield washer fluid.
