Abstract: This invention relates to an apparatus for cleaning accumulated carbon and other material from the ring grooves of pistons. The apparatus includes a cylindrical housing adapted to accommodate a piston therein, and a plurality of mutually spaced apart cleaning blades disposed along the axial length of the interior of the housing. The blades are adapted to insert into ring grooves of a piston when the piston is placed within the housing. Biasing means are included to urge the cleaning blades into the ring grooves, so that as the piston is rotated with respect to the housing, the blades can clean out accumulated carbon and other foreign material. The apparatus also includes means disposed within the housing for holding the piston snugly within the housing to prevent radial displacement of the piston as it is being rotated within the housing.
