While washing the car yesterday I noticed that there is great deal of staining on the windshield. It looks like simple watermarks, but I can't get the stains off. I've tried everything from window cleaner to rubbing compound on the inside and outside of the glass. Nothing even makes a dent in the stains. This stuff is so stubborn I can't tell if the stain is on the inside or outside of the glass. Thoughts?

Sounds like water drops that have sun-dried on the car. Tap water from the hose will usually leave behind mineral deposits if not wiped down before the sun bakes it. So a clay bar works on them?

That's one of the reasons to dry your car after washing with municipal water supplies or any high mineral content water. I recommend plain vinegar to clean the glass. It does a great job removing water stains - DO NOT USE on bodywork (but I really didn't need to write that - DID I !? ! ) .

I have something more permanant......its like a line where the windshield wiper stops in the middle of the windshield. You cant see it when its dry but you see it when its raining....weird and annoying.
