A casing attached to or made part of a standard windshield wiper assembly that extends a scraper blade to the surface of a vehicle windshield to dislodge insect remains and debris, with the aid of the wiper motion and a vehicle mist system. Once the desired cleaning effect is accomplished, the scraper is then retracted into the casing to allow normal operation of the vehicle's windshield wipers.
