How can I remove water spots from glass and paint surfaces?
Most common water spots are caused by mineral deposits. Vinegar and water does a great job at neutralizing these marks. The Auto Spa also recommends the use of the Clay Magic Clay Bar for a safe and thorough method in removing water spots. It is also very important to wash off water spots as soon as possible. If the vehicle is left in the sun for prolonged periods of time (4 days or more), there is a good chance that the water spots will actually etch into the clearcoat. This makes it very difficult, sometimes impossible, to remove the water spots if they have been on the paint for long periods of time.
