Abstract

The subject invention (1) provides a method and apparatus for cleaning the exterior of a sprayer in the area of its spray nozzle (2) and any existing air nozzles. The appropriate part (2) of the sprayer is inserted through an opening (4) in a container (3). All of the areas of the sprayer to be cleaned are directly charged with a cleaning fluid by a bow-shaped array of nozzles moving in a hemispherical path around the part (2) to be cleaned. The invention is particularly suited for the fully automatic cleaning of a spray gun mounted on a painting robot.
