Ordinary blue windshield washer fluids are fine for removing dirt and the occasional insect, but for serious driving, they're not quite up to the task. Autobahn-tested P21S Windshield Wash Booster removes the greasy, oily road film that reduces your forward vision--especially on rainy nights. With a clear, streak-free windshield, you'll be able to keep an eye on the road ahead. You'll also replace your wiper blades less frequently because they won't work as hard. 8.4 oz. (250ml bottle) with special measuring tip for spill-free use--without a funnel. Made in Germany.
