Abstract
An article and process for cleaning relatively inaccessible and recessed surfaces, including a shaft having a first end opposite a second end with a cleaning head assembly, including a movable strip of buffing material, at the first end of the shaft. The article has an actuator at the second end of the shaft; and a connector coupling the cleaning head assembly to the actuator to move the movable strip during positional change of the actuator. Repeated positional change of the actuator produces reciprocatory movement in the movable strip of buffing material to produce a rubbing, cleaning action of the material against a recessed surface.
