After the first car window itself disappointment wanted to make wide. It remained small water spots that also did not want to disappear so quickly. Then have not given up and gradually externally and internally cleaned after all slices of my car only with a slightly damp cloth. When I arrived back at the first disk, all droplets were there since disappeared and the disc was streak-free clean. Even when viewed against the low sun no streaks or drops residue is seen - and all without chemical additives - incredible.
