My MAXIMA windows all have small circular spots which I cannot remove with any window cleaner that I have tried so far. Commercial window clean products promise much but the spots always remain. The small spots look similar to water deposits I see on glass shower doors. What glass cleaner REALLY works for shower door glass? WOuld that work for my car windows? What cleaner works for you folks? IF these spots are salt or calcium deposits, would CLR remove spots without damaging the windows?
I appreciate any help. Thanks, Dave_s
