Abstract: A method for cleaning cathode and/or anode plates which are obtained in the electrolytic refining of metals and which are lifted in groups suspended on bars or lugs from the electrolytic bath and thereafter the plates are washed by passing in succession through the washing operation individually or in pairs inclined in substantially V-manner with respect to each other. Additionally, three or more plates, inclined away from each other substantially in fan manner, may pass through the washing operation. The flat sides of the plates are sprayed at least partially by nozzles which execute a relative movement along the flat sides.
