I need a solution, a strong solution, on how to get rid of the water spots on my windows. I am sure its on the out side, and they look like little round scars from water drops. You can see them if you look for them, but they are not real noticalbe if you dont go looking for them. Does any one know what i meen? I have tryed stuff like vinigar and lime away or lime out. Nothing takes them off. Its almost like the damage is permanent on the glass. Most water spots come off, but this is horrid. Does any one else have this problem?
