A windshield wiping insert for windshields, windows, and the like includes an intermediate, elongated, formed metal strip which provides the interface between the superstructure of the windshield wiper and the flexible wiping member which is placed in direct contact with the window surface to be wiped or cleaned. This intermediate support strip includes a pair of outwardly extending flanges which are adapted to be slidably received by the particular super structure and between these flanges is a center channel wherein a portion of the flexible wiping member is clamped and securely retained. Another portion of the flexible wiping member protrudes downwardly beyond the lower surface of the intermediate support strip and terminates in an enlarged quadrant shaped portion which is configured with two edges and a convex curved surface therebetween. With movement of the windshield wiper assembly, this enlarged portion flexes first in one direction then in another and the amount of flexing or bending is controlled so as to present one edge or the other edge in contact with the windshield surface so that a scraping action occurs as the windshield wiper moves across the window. The intermediate support strip is initially formed with a convex shape in its length dimension in order to provide improved force distribution along the wiping edge of the windshield wiper.
