An apparatus is arranged to clean a cylinder with cleaning liquid being supplied. The cylinder includes an outer surface to which impurities are adhered. The impurities are removed from the outer surface when cleaning. The apparatus includes a spray bar into which the cleaning liquid is directed with pressure. The spray bar comprises tube means which includes nozzle holes formed therein for spouting the cleaning liquid. The tube means is formed of elastic material and elastically deformed by the pressure of cleaning liquid to open the nozzle holes and spout the cleaning liquid. The tube means is elastically restored, when the cleaning liquid is not directed with pressure into the spray bar, to close the nozzle holes.
