Provided is a method and device for removing chemically dissolvable support material from objects created by a three-dimensional printing process. In one exemplary embodiment a tank for holding a cleaning solution has a cleaning section and a fluid handling section, and a full level below a top rim thereof. A generally box-shaped parts basket configured to be removeably installed within the cleaning section of the tank has four fluid impermeable walls, a bottom panel perforated throughout with an array of holes, and an openable top cover, wherein the openable top cover is below the full level of the tank and the bottom panel of the parts basket is supported above a floor of the tank when the parts basket is installed. A fluid pump disposed in a fluid handling section of the main tank is configured to inject a fluid stream into the parts basket at a downward angle with respect to horizontal, and at a lateral angle with respect to a line passing through a center of the parts basket, with sufficient velocity and flow rate to induce a fluid current that circulates around an interior of the parts basket as it continuously descends and exits the parts basket through the perforated bottom panel.
