I take a rag and a pail of hot water with a little soap in it and go up on the roof of my motorhome and hand wash it.? I rinse the rag frequently and the water gets all milky-colored, especially the front cap area.? I also get some white milky-colored streaks down my windshield and the sides of the motorhome when water runs off of the roof (when there is heavy dew or a light rain).? Something on the roof surface is reacting with the water to turn milky-colored.? What causes this and what can be done to prevent it?
