A method and apparatus for cleaning a pipeline. The method comprises: a) providing a flow of a first fluid, such as water, through a conduit (1), at least one orifice opening (FO1, FO2) into the conduit, such that a second fluid is drawn through the orifice into the first fluid at a specified rate relative to the rate of flow of the first fluid, to provide a flow of a solution of the first fluid in the second fluid of predetermined concentration; b) supplying the flow of the solution through the pipeline; c) allowing such solution to remain static in the pipeline for a predetermined time; d) providing a flow of the first fluid through the conduit, while preventing the second fluid being drawn through the orifice into the conduit, thereby flushing the solution from the conduit without flushing the pipeline; and e) providing a flow of the first fluid through the conduit and the pipeline to flush the solution from the pipeline. In one embodiment the first fluid is water, the second fluid is detergent, and the pipeline is a beer dispense line.
