Abstract: A liquid-powered device is provided for washing the terminal-end portion of an elongated member, such as a hand, extended therein. Liquid, under pressure, energizes a positive-displacement motor which powers a rotational laving element wetted by the liquid after it has exited the motor. A housing which confines, collects, and vents used liquid has an entrance opening for entry of the terminal-end portion of an elongated member into washing relationship with the laving element. Provision can be made for supplying soap and the like in solid or liquid form within the housing.
