Abstract: Apparatus and method are provided by this invention for cleaning of internal combustion engine components. The method consists of heating the components, removing of dry debris from the components by blasting the component with shot and then physically shaking the component to remove the shot from cavities in the article. The apparatus includes a heating unit for heating of the components to a temperature to burn combustible debris and leaving the components coated only with dry debris and debris removing apparatus operating on the heated components. The debris removing apparatus includes an airless shot blast device for throwing of shot against the article and mechanism for support of the article in the path of the shot and revolution of the article about a horizontal axis. A carrier is provided for a plurality of the components and the carrier is supported for revolution about a horizontal axis during blasting with shot and is revolved and oscillated about transverse axes for removing of shot.
