The tool statically engages the surface of a rotary faced buffing pad in order to clean and recondition the pad. The tool also provides for controlled and predictable return motion to a first semi-circular portion of the buffing pad on occasion of travel of the tool with respect to the pad over the pad center line and onto a second semi-circular pad portion not amenable to engagement. | |
