Abstract
A brush configured to clean, buff, and polish a surface, comprising a core member having a central axis, a periphery and a sheet of material, the sheet of material comprising closed-cell silicone foam rubber and having a first free end portion. The sheet of material is attached to the core member with the free end portion extending away from the periphery substantially parallel to the central axis of the core member. The core member includes a flat surface adjacent the attachment of the sheet of material. The core member and the sheet of material are configured for relative movement with respect to the surface in at least a first direction. The motion in the first direction causes the free end portion of the sheet of material to contact the surface at a non-zero velocity, and produces at least one of the cleaning, buffing and/or polishing action on the surface.
