An arrangement for cleaning paint spray-guns by use of a small tank or vat with a confining hood at its top which is divided into a plurality of laterally disposed compartments by means of vertical partitions which extend downwardly from the top of the tank into a body of liquid chemical solvent or thinner, which floats above a body of water at the bottom of the tank. The partitions extend through the body of solvent and partially into the mass of water. A horizontal cover or shelf at the top of the tank separates the main portions of the hood compartments therefrom, leaving a communicating passage between each tank and hood compartment at the rear end of the latter. An opening in the shelf at the front thereof in each compartment permits an operator to insert the suction tube of the spray-gun into successive compartments for scavenging the spray-gun with successively cleaner masses of solvent as the gun is directed towards the rear of the hood, without discharging the paint impurities and thinner into the atmosphere. The impurities drop to the bottom of the tank into the body of water, for periodic removal, with or without the cleaning solvent.
