    Abstract: The cleaning of barrel type containers, particularly beer kegs which have a fitting including a riser pipe which extends into the keg, is accomplished by incrementally increasing the level of a cleaning liquid which has been introduced into the barrel and, between each step of injection of cleaning fluid, causing turbulent motion of the liquid in the barrel by means of the injection of preselected volumes of a gaseous medium at a point below the surface level of the liquid cleaning fluid.
