Abstract
A spark plug cleaner is constructed as an upright canister with outwardly directed openings into which spark plugs are inserted. A vertically mounted motor driven impeller sucks grit from an axial center of the canister and flings it toward the spark plug sockets. A grit recovery floor is provided below the impeller and sockets and is configured concave upward. A suction guide fits coaxially over the collection floor and also slopes concave upward toward the center of the impeller. An annular vacuum channel is formed between the collection floor and the suction guide to concentrate impeller suction on spent grit as it falls to said collection floor and to increase grit velocity and density to the impeller.
