For cleaner windows the inexpensive way use 1/2 cup cornstarch to a quart of warm water. Stir well and put in a spray bottle and your windows will come out crystal clear.
tried everything to eliminate hard water spots off outside;vinegar, newspapers, window cleaners, etc. Help! Nothing works! (02/17/2006)
Try rubbing alcohol! It should cut right though the hard water spots .. Then use regular cheap shaving cream, not the gel, to prevent the spots from reappearing! Works great on shower doors.
