 Not only what mixture to use, but what kind of rags, what kind of towels or rags or whatever. I know some people clean windows. In fact, we do it around the house, windows at the house with newspaper. And why newspaper works well, I don't have any idea. It has ink on it and everything, but for some reason it works well on the windows at home. I don't know if that would be the best choice for windows in a car. I kind of doubt it. Probably micro windows.
