An apparatus suitable for cleaning a surgically prepared bony concavity includes a body portion adapted to supply pressurized fluid (preferably carbon dioxide gas) to the concavity and aspirate surface debris. The apparatus further comprises a head having an orifice with a plane, circular rim having a diameter less than that of the bony concavity. A method for cleaning a surgically prepared, concave, generally hemispherical bony cavity includes the steps of: covering a region of the hemispherical bony concavity with a cleaning head; supplying a pressurized fluid to the region covered by the cleaning head, and collecting the pressurized fluid from the covered region with a surface debris aspirator coupled to the cleaning head. A cleaning head having a generally circular orifice substantially seals and encloses a spherical zone to be cleaned.
