ABSTRACT:
For cleaning spraying apparatus, such as a spray gun, the spray outlet is sealingly coupled to a conduit coupling (possibly after removal of an air cap). Cleaning solvent is then passed through the gun and coupling, and is collected in a reservoir 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 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 open.
