A disc-shaped wheel cover, or shield, with an arm rotatable around the shield center includes a pressurized fluid container at the arm distal end filled with cleaning chemical, extending on the arm radially beyond the shield. A nozzle on the container directed axially disburses chemical toward a tire sidewall. Alternatively, the arm may comprise a grasping member on its distal end adapted to receive a commercially-available pressurized container. A wheel may also be mounted under the container to support the arm distal end a predetermined distance from the tire as the wheel rolls around the tire sidewall. The shield is removably attached to a wheel rim flange by an elastic skirt around the shield circumference at shield closed end with a skirt open end adapted to attach to the wheel. Thus, in operation the elastic skirt is stretched about the flange. A member less flexible than the elastic skirt, such as a bead or a relatively inflexible plastic or metal rod, may be provided around the skirt adapted to fit between the rim flange and the tire. Equivalently, the skirt may comprise a flexible sheet with an elastic ring at its open end, which also may comprise a bead, or generally less flexible member, or a plurality of arcuate rods circumferentially around the skirt open end, separating to spread over a flange and then contracting together again for engaging around the flange.
