An apparatus for cleaning a coating gun nozzle used in spraying the inner surface (12) of cans (14) with a coating material comprises a cleaning solution spray nozzle having a cleaning spray extension (68) and a cleaning spray nozzle (70) for spraying a cleaning solution onto the coating gun nozzle (20) to remove oversprayed coating material collecting thereon. The coating gun nozzle (20) is disposed at an end of a coating gun nozzle extension (22). A single spray shield (110) is disposed over the end of the coating gun nozzle extension (22), and has a flange portion which extends at least to an external surface of the cleaning nozzle extension to shield the components of the apparatus from oversprayed coating material. A check valve mechanism (144,148,150) disposed within the cleaning spray extension (68) prevents cleaning solution from dribbling or drooling from the cleaning spray nozzle (70). A control system controls the operation of the apparatus. <IMAGE>
