Claim:
An apparatus for cleaning a rotary, dual action or random orbital power driven buffing pad having a buffing face, while the pad is mounted on an operating buffing machine, the apparatus comprising: a reservoir for a liquid cleaning solution including an outer wall having a peripheral upper edge defining an open upper end; a base plate supported on the upper edge of the reservoir and having an outer wall extending downwardly into the open upper end, the base plate having an annular support surface; a wash plate having a foraminous upper surface supported over the base plate support surface and connected thereto with a biasing arrangement adapted to permit vertical movement of the wash plate in response to manual downward operator movement of the buffing pad face against the surface of the wash plate; a positive displacement pump mounted in the reservoir, the pump having a cleaning solution inlet on a lower end and a housing including a cleaning solution outlet on an upper end in a closed path providing pressurized liquid communication with the upper surface of the wash plate, the pump housing attached to the base plate support surface and having a spring-biased pump actuating plunger, including the cleaning solution outlet, in operative engagement with a lower wash plate surface to deliver cleaning solution from the pump outlet into the wash plate, through the foraminous surface of the wash plate and against the pad face in response to the downward operator movement.
