Has anyone ever thought of a good way to remove water spots that form on the inside of the back door glass of an XC70 where the third brake light is? When I have the car washed and the back door is open and they spray glass-cleaner on the window, some of it runs downhill between the center brake light and the glass creating water spots. Anybody know of a good way to remove these spots without removing all the molding around the glass and unscrewing the brake light? There is a very small space between the light and the glass...only a couple of mm.
