PROBLEM TO BE SOLVED: To provide a detergent composition which is suitable for an automatic dishwasher having such a control mechanism that electrical conductivity of a cleaning liquid is monitored and whether the detergent composition is supplied or not is determined.SOLUTION: The detergent composition of a liquid state or a solid state is used for cleaning an object to be cleaned by using the automatic dishwasher 1 having such the control mechanism that electrical conductivity of the cleaning liquid is monitored and whether the detergent composition is supplied or not is determined. The detergent composition contains a nonionic surfactant (A), a polymer electrolyte (B), an alkaline agent (C) and a chelating agent (D). When 0.5 g of the detergent composition of the solid state is dissolved in 1 L of water, the electrical conductivity of the detergent composition-dissolved water is 1.2 mS/cm or higher at 60°C. When 1 g of the detergent composition of the liquid state is dissolved in 1 L of water, the electrical conductivity of the detergent composition-dissolved water is 0.7 mS/cm or higher at 60°C.SELECTED DRAWING: Figure 1 |
