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 firs t fluid is water, the second fluid is detergent, and the pipeline is a beer dispense line.
