Next I find an empty gallon bottle (such as a milk bottle seen in the photo above) and rinse it out. Using a funnel, I fill it about 3/4 of the way with distilled water. Then I add eight ounces of isopropyl alcohol from the bathroom. Then I give it a short squirt of dish detergent. Then I finish filling the bottle with distilled water. Finally, I put in four drops of blue food coloring and give the bottle a shake. Voila! Washer fluid for about forty cents!
It works great and the alcohol prevents it from freezing. There are some formulas that use ammonia instead of alcohol, but I prefer alcohol in the mix. So there you have it—a cheap way to fight inflation.
