PROBLEM TO BE SOLVED: To provide a cleaning fluid inexpensively which uses no chemical substances and which is safe and easy to mass-produce. SOLUTION: The cleaning fluid contains the water in which a polyvalent cation is removed and a sodium ion is added, and is able to remove the grime attaching to a wash by the action of the water, when applied to a wash. A wash cleaned with this cleaning fluid has no chemical substance residue liable to be caused frequently when cleaned with a cleaning fluid using a chemical substance such as a surfactant, and thus is safe, and besides is difficult for a new dirt to stain because the scale is difficult to remain. Consequently, this cleaning fluid is effective especially when used as a cleaning fluid for use in , for example, sinks in the kitchens, tableware, foods, washstands, bath rooms, toilets, vehicles and clothes.
