A valve cleaning machine consisting of a cabinet in which are mounted a plurality of jet nozzles adapted to eject compressed air jets containing granular abrasive material, each adapted to clean a given peripheral portion of an automotive engine valve. The valves to be cleaned are mounted in a rotating carousel so that each valve is presented sequentially to each of the nozzles, and the valves are rotated in the carousel to insure that the entire periphery of each valve is presented to each nozzle. The nozzles may be operated simultaneously if sufficient compressed air capacity is available, or one at a time in sequence if only a lesser compressed air capacity is available. The polished bearing surfaces of the valve stems are protected from the abrasive air blasts, and provision is made for alternative use of the device for cleaning single hand-held objects when desired.
