A container washing apparatus for washing containers such as beverage cans. An elongated liquid supply pipe includes a plurality of angled fittings connected along opposite sides of the pipe. Each fitting includes quick connect and disconnect structure on its outer end for mating with like structure of a fan spray nozzle. The fan spray nozzles may be turned onto the ends of the angled fittings in a quick twisting bayonet motion to align each of the elongated fan spray patterns parallel to one another and to the longitudinal axis of the pipe. In a preferred embodiment, the container washing apparatus is used in a washing system including a liquid permeable conveyor for moving a plurality of containers, such as beverage cans, past a plurality of elongated spray pipes of the invention which are mounted adjacent upper and lower sides of the conveyor in a perpendicular orientation relative to the movement of the conveyor.
