Abstract: A method is disclosed for rinsing a cleaned object whereby cleaning chemical liquid adhered to the object is substantially removed therefrom while substantially reducing the amount of pure water used for rinsing. The object with cleaning chemical liquid adhered thereto is immersed in a rinse bath filled with pure water, so that the cleaning chemical liquid may be rinsed off therefrom while pure water is continuously fed to the rinse bath. A neutralizing chemical liquid of alkalinity or acidity opposite that of the cleaning chemical liquid is added to the pure water in the rinse bath by feeding the neutralizing chemical liquid using a feed pump and a pump controller. Thus, the cleaning chemical liquid is neutralized by the neutralizing chemical liquid, to thereby be converted into a salt readily soluble in pure water, which salt is then discharged together with the pure water by overflowing the rinse bath.
