Easy removal of road grime from automobile glass. Before washing auto, wet the window glass and let most of the water run off. Sprinkle powdered whiting (found in Paint Dept.) and scrub window with a plastic type kitchen sponge. Leave the powder to dry, now clean all the windows. As you begin to wash the auto, the soap suds will remove the whiting and the glass will be clean. (Whiting is a super fine polish compound; will not harm glass; but will leave a white powdered residue if you don't wash it off, the same as the old auto waxes...)
