An elongated blade has an interior section and an exterior section. The interior section is adapted to be releasably coupled to a wiper arm. The exterior section has a W-shaped configuration with outer walls and inner walls. Two parallel edges are formed by the outer walls and the inner walls. The parallel edges are positioned in sliding contact with an exterior surface of a windshield during operation and use. A coupling assembly releasably couples the elongated blade to the wiper arm. The elongated blade is adapted to oscillate with respect to the wiper arm in response to a reversing of directions by the wiper arm and the elongated blade.
