A suction cleaning apparatus or suction cleaning horn is a generally cylindrical barrel or sleeve with an insertion cone to control and direct the distal tip of a suction tool into the bore of the barrel. A stylet is secured within the suction cleaning barrel and aligned on the longitudinal axis of the bore such that insertion of the suction tool into the cleaning barrel inserts the stylet into the channel of the suction tool to mechanically clear any obstructions of the suction tool. The distal end of the suction cleaning horn may also include one or more holes or vents to permit cleaning liquid to be drawn into the bore of the cleaning horn and into the suction tool channel to help clear obstructions in the suction tool.
