DIY Windshield Wiper Fluid

You can mix up all kinds of nonsense and spray it on your windshield oil might not be a good component to having that mix but ammonia window cleaner what do you want Dawn and something I mean I'm sure the environmentally friendly manufacturers method and all that must make glass cleaner that somewhat acceptable and so on this would be something to read on cleaning sites and environmentally friendly sites and look at some labels of window cleaner that's made by companies that are responsible like method and whoever see what their components are in them try it on your windshield and see if it's workable. The blue stuff the orange stuff from Rain-X and all that is bad for the environment eh well considering my jug has been full for about 5 years and almost never get squirted unless the wife is driving the car which is quite rarely so I never feel it and almost never use it when I clean off my windows it's usually done while I'm spraying off the car in the morning with the garden hose so as always that old cars don't need to have a lot of time spent on them cleaning and washing that's why I drive them people expect an old car to be well not as clean as a new car.

 

I make my own, in a jug that previously held the storebought stuff- so about one gallon at a time. Water, a couple of drops of Dawn or similar dishwashing liquid (really, just a couple drops!) and some isopropyl alcohol to prevent freezing.

5 parts water to 1 part alcohol is about right for any temperature we'll get in a mid-Atlantic winter. You could probably get away with less or even none.

I use distilled water since my well supply has a lot of minerals in it.

 

Here in Maine folks tend to mix water and antifreeze 50/50 maybe with a little dish soap.
