A removable washer attachment providing a closed system for use in washing containers such as chemical or pesticide drums including an insert secured to a formed opening in one wall of the container. The insert has a first portion extending exteriorly of the container, a second portion depending interiorly of the container, and a bore extending axially therethrough for receiving a suction tube. The insert is fluid-tight sealingly engaged with the formed opening. Another seal is provided between the bore and a suction tube inserted therein. When it is desired to wash material from a container, washing fluid is admitted into the bore and is channeled through passages into curved notches disposed in a lower segment of the interiorly depending portion. The washing fluid is sprayed upwardly and contacts the inside top and side walls of the container or a disposable bag if the container utilizes such. Residue material is washed downwardly to the bottom of the container where it is removed through the suction tube.
