PROBLEM TO BE SOLVED: To provide a press roller for stain removal which rubs and loosens the greasy dirt of clothes, such as the dirt on the collars of shirts and the stains of fibrous materials, such as carpets, which cannot be rubbed and a sheet for stain removal as well as a caulking method which makes loosening difficult. SOLUTION: The press roller for stain removal is constituted by freely rotatably fitting the front end of an arm 3 fastened to a handle 2 with a roller 6 formed like a gear or with arbitrary patterns on a tread. The sheet 21 for stain removal is constituted by forming arbitrary patterns 7 on the surface of a sheet-like stretchable material. The caulking method comprises cutting screw threads at the front end of a shaft and passing the shaft through a fixing member, thereafter tightening and fixing a caulking nut 9 formed with a notch at the angle at which the top surface of the nut and an internal screw thread forming portion intersect, then pressing the same.
