A device for washing outer cylindrical surfaces of a rotary printing machine is disclosed. The device uses a washing cloth which is unwound from a supply roll and, via a pressing-on rail, supplied to a take-up roll. The washing cloth is pressable by the pressing-on rail against the outer cylindrical surface to be washed. To simplify operation only the two washing-cloth rolls with the washing cloth are changed and the other components of the washup device remain inside the machine.
