The system comprises a plurality of on-line cleaning tanks, through which continuous metal strip is passed, and a plurality of storage tanks, each containing a different cleaning solution. Different combinations of cleaning solutions are transferred to the on-line tanks from the storage tanks by selecting a particular combination or sequence of cleaning solutions in accordance with the type or composition of metal or metal alloy comprising the strip and automatically feeding the cleaning solutions to the on-line tanks in accordance with the sequence selected. The on-line tanks and storage tanks are interconnected by a network of conduits, pumps and valves which are automatically conditioned by a control element to operate in response to the selection of a particular cleaning sequence. Upon completion of a cleaning operation, each of the solutions is returned to its corresponding storage tank.
