A windshield wiper spray nozzle offset device includes an offset arm and an attachment device. The offset arm includes an offset leg extending from a clamping base. The attachment device is preferably a clamp plate and at least two fasteners. The at least two fasteners are preferably used to secure the clamping base and clamp plate to opposing sides of the wiper arm. However, other attachment devices may also be used, such as spring clips. The wiper arm may also be modified by making the offset arm as an integral portion of the wiper arm. A nozzle snap-on retainer and a hose snap-on retainer are removed from the wiper arm and snapped on to the offset leg. The offset position of the spray nozzle increases the spray area thereof.
