Abstract: A rear view mirror mounted on the side of a truck is equipped with an air deflector and fluid dispenser for clearing foreign material from the viewing surface of the mirror. The air deflector has a generally flat forwardly directed section joined to a curved middle section. A terminal section joined to the curved section has a lip forming a passage for collecting foreign material and fluids from the air directed toward the viewing surface. The fluid dispenser has an elongated tube provided with a plurality of fluid discharge orifices. The tube is mounted on the lip with a plurality of releasable clips. Fluid under pressure supplied to the tube is directed onto the one side edge of the mirror and carried across the mirror surface with a moving sheet of air to clear mirror surface of foreign materials, such as insects, dust, dirt, mud, snow, ice and rain.
