After you wash your car take the sprayer off the hose and let the water run over the surface of the paint, it will take most of the spots off, then dry with clean towels, a chamois or a synthetic shamois. If you have water spots that don't wash off you need to use some clay bar system or a cleaner wax to get them off. Never wash your car and not dry it off, water spots are hell to get off.

My black truck sits on my driveway and gets watered by the sprinkler system and I had spots that didnt wash off, in fact you could feel them. I used Maguire's cleaner wax on it and most of them came off the first time, almost all came off the second time. I now rearrange cars when I water so none of them get watered!
