P21S Windshield Wash Booster

Autobahn-tested P21S Windshield Wash Booster removes the greasy, oily road film that builds up on windshields and impairs forward vision. Add it to standard washer fluid for a clear, glare-free view--even on even rainy nights. Helps wiper blades last longer, too. 8.4 oz. (250ml bottle) with special measuring tip for spill-free use. Made in Germany.
