An apparatus for washing paint spray guns and associated equipment with a liquid solvent for the purpose of cleaning and removing paint therefrom after use in painting operations. The apparatus includes a cleaning chamber having solvent dispersing nozzles therein, the nozzles being structured and disposed for spraying the liquid solvent onto exterior and interior surfaces of the spray gun, paint canister and other equipment supported within the cleaning chamber for cleaning thereof. The used solvent is collected in a holding chamber having a float switch therein which activates a solenoid controlled valve upon the used solvent reaching a predetermined level, releasing the contaminated solvent into a distillation chamber for boiling. Purified vapors pass through a condenser where they are cooled to a liquid state, yielding pure solvent which is directed into a clean solvent tank. A pump circulates the purified solvent from the clean solvent holding tank to the dispersing nozzles in the cleaning chamber.
