Wolfgang Concours Series WG-4300 Glass Polish, 16 fl. oz.

I can never get my windshield perfectly cleaned - I hear that all the time at car shows, and the recurring issue that I see is water spots, road film, and industrial fallout. When I say "see," I mean literally - the windshields on most of these vehicles are in terrible shape. Glass cleaners are designed to remove topical stains, like finger prints, not the tough stuff like water spots and road film. Twice a year you need to cleanse your glass of the aforementioned contaminants using a specially designed glass polish, like Wolfgang Perfect Vision Glass Polish.
