A self-contained water treatment device to facilitate the washing of articles, such as clothes in a conventional washing machine, includes a body, a first electrode in the form of a layer of paint of an electrically conductive material integrated with the body, and a second electrode of a layer of paint of an electrically conductive material integrated with the body. The electrically conductive paints of the first and second electrodes have different electrochemical potentials and are at least in part spaced apart from one another on an electrically insulative surface of the device so as to be electrically isolated from one another. The device also has sufficient buoyancy so as to float in water. In use, the device is placed into a reservoir of water, such as the tub of a conventional clothes washing machine or dish washing machine, and the tub is filled with water and the articles to be washed. When the machine is turned on and the water is agitated, the device circulates freely throughout the volume of water throughout the water in the tub and the water is in contact with the electrodes. Thus, the water is ionized due to the electric potential established between the electrodes and such ionized water is more effective in washing the articles in the tub. Alternatively, the electrodes may be in the form of mixtures of electrically conductive material and a plastic binding agent, with the body and the electrodes each being a molded segment of a sphere so as to together constitute a ball-shaped device.
