For cleaning a spray gun 10 its air cap is removed and its spray outlet 16 is sealingly coupled to a conduit coupling 40. Cleaning solvent is then passed through the gun and coupling, and is collected in a reservoir 26 without being sprayed into the open air. For a pressure feed gun, the solvent is fed without the use of a compressed gas stream. The cleaning action may be enhanced by injecting air into the solvent adjacent its entry (14) to the gun. Solvent (and injected air) may also be passed through the gun in reverse direction. The process may be automated, with the gun held in a housing with its trigger clamped (20) open. <IMAGE> |
