ABSTRACT:
Method comprises positioning a spray gun and its cup-connecting means in a stationary support, and its gun cup in a rotatable cup holder in a closed chamber. Then, compressed air and cleaning liquid is passed through the gun and cup-connecting means, while simultaneously rotating the cup holder and spraying the exterior surfaces of the cup, gun, and cup-connecting means and the interior surfaces of the cup. In a preferred embodiment, the spray from the gun rotates the cup holder. The device comprises the chamber, the gun support, a rotatable cup holder, a pool for cleaning liquid, spraying means, internal means for filtering and distributing cleaning liquid to the cup connecting means and the spraying means, and means for introducing compressed air from outside the chamber into a compressed-air manifold and then distributing the compressed-air to the gun and spraying means. The device also includes means for venting air that is exhausting from the chamber and means for absorbing fumes in the exhausting air.
