    Abstract: A method for cleaning articles with pellets. The apparatus has a housing where an article can be cleaned with pellets. A first auger is rotatably disposed in the housing and rotatably passes therethrough for conveying pellets out of the housing after the pellets have been discharged into the housing for contacting an article for cleaning. A second auger is rotatably disposed on the outside of the housing and communicates with the first auger for receiving and transporting pellets therefrom. The second auger has a sleeve having a structure defining at least one opening wherethrough pellets pass after being transported. A rotating impeller is mounted on a side of the housing and receives the pellets through the opening of the sleeve and propels the pellets towards the article.
