Provided is a detergent composition for peeling a resin mask which has excellent resin mask removability and has a small drainage treatment load. The present invention relates to a cleaning composition for peeling off a resin mask, which in one aspect contains an inorganic base (component A), an organic solvent (component B), water (component C), and Hansen solubility of component B. The coordinates of the parameters are within the range of a sphere with a radius of 1.5 MPa 0.5 centered on δd = 17.5, δp = 5.0, and δh = 11.5. When using the detergent composition, the content of component C is 85% by mass or more, and component A is relatively The mass ratio (A / B) of the component B is 1 or more and 60 or less. |
