ABSTRACT:
A field of windshield wiper cleaning elements (10) is arranged above each wiper's resting position on a windshield (16). It includes several horizontal rows of slightly raised round dots or squares (11-15, 21-25) applied to the exterior surface of the windshield. The cleaning elements graduate from a maximum size along the bottom edge of the field, to a minimum size along the top edge of the field. The wipers scrape across the cleaning elements whenever they are operated, so that they are cleaned automatically. Cleaning effectiveness is improved by the graduated sizes of the cleaning elements. They are made by applying a ceramic ink on the windshield and firing the windshield, so that they are extremely durable.
