An apparatus for degreasing solid and/or mass-produced parts, such as small metallic parts comprises a drum with a perforated drum wall rotatable and drivable around a vertical axis. A charge opening is furnished at the top and a discharge opening furnished at the bottom. The discharge opening is closable by an axially movable floor closure. A stationery outer ring channel surrounds the drum and exhibits at the bottom an outer ring trough with discharge port. An inner ring channel is disposed between the outer ring channel and the drum and axially adjustable by way of an adjustment member and including an inner ring trough at the bottom. Feed lines for treatment agent lead into the drum. The inner ring channel is formed adjustable from the starting position, releasing the drum perforations, into a center position covering the drum perforations on the outside, and into a sealing position for sealing the drum.
