ABSTRACT:
A surfactant is added to anodic or cathodic water obtained by electrolyzing deionized water or high-purity water. Then, an object of treatment is treated with the anodic or cathodic water containing the surfactant. The object of treatment may be treated, in this way, while irradiating it with an ultrasonic wave having a frequency between 30 kHz and 3 MHz. Furthermore, the anodic or cathodic water is continuously jetted or dropped onto the object of treatment from a nozzle, while irradiating an ultrasonic wave at least at a part in the feed pipe of the anodic or cathodic water.
