Abstract: A system for washing clothing includes an alkaline ionized water-generating unit, an alkaline ionized water-generating medium-supplying unit, an alkaline ionized water storage unit, and a washing tub. The alkaline ionized water-generating unit is configured to generate alkaline ionized water. The alkaline ionized water-generating medium-supplying unit is configured to supply the alkaline ionized water-generating medium to the alkaline ionized water-generating unit, and the alkaline ionized water-generating medium generates the alkaline ionized water. The alkaline ionized water storage unit is configured to store the alkaline ionized water generated by the alkaline ionized water-generating unit. The washing tub is configured to wash an object.
