Abstract
A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprises providing a core member having a plurality of C-shaped grooves having respective openings and at least one sheet of material. The at least one sheet of material comprises a closed-cell silicone foam rubber and is attached to the core member using a coil-shaped element and has a first free end portion extending away from the core member. The core member moves by rotation in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern. The sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.
