Abstract: Lubricant pails are quickly washed and dried during an automatic machine operating cycle which is initiated by manual placement of each pail on a holding mandrel and simultaneous operation of an adjacent limit switch. Mandrel and pail rotation are initiated and a rotating brush is moved into engagement with the exterior of the rotating pail while cleaning solvent is delivered onto the pail throughout its length. The brush cleaning cycle is followed by a solvent rinse cycle, which in turn is followed by a blown air drying cycle, after which the clean pail is ejected from the mandrel by positive air pressure. The several cycles are timer controlled. In a modification, closed end pails are laterally loaded on a roller bed.
