A dual durometer windshield wiper blade assembly comprises an elongated elastomeric wiper blade with an integral squeegee rib of relatively low durometer material. The blade has an integral hinge of circular cross-section coextensive with the squeegee rib and of a relatively high durometer. A high durometer plastic elastomeric blade holder supports the wiper blade at angularly spaced positions upon reciprocation of said assembly.
