Cut out several pieces of non-woven fabric with length and width of 100mmx70mm (the matrix is synthetic fiber, the basis weight is 40±4g/m ² , Daiwa Textile Co., Ltd.), and each of the implementations in Tables 1 to 4 are added to these non-woven fabrics. 1 ml of the cleaning composition of the example and the comparative example was used to prepare a hard surface cleaning sheet ([mass of the cleaning composition/mass of the substrate in the non-impregnated state (dry state)] x 100-320% by mass). Then wrap it in an eraser (15mmx40mmxl Omni)-h that has been wrapped in aluminum foil. The surface of the stainless steel was wiped once with the 15mmx40mm surface of the eraser wrapped with the cleaning sheet impregnated with the cleaning agent composition of Example i. Wait for 10 minutes, weigh the stainless steel again; t, set the weight ih as W2. The stains on the stainless steel sheet are thoroughly removed, dried and weighed, and the weight is counted as W0. Cleaning power two [(W1 W2) / (Wi-WO) j*i00 (%)

When measuring WO, W1 and W2, take 5 decimal places for calculation. Record the calculation results in the table. Then, repeat the above operations to complete the remaining examples/comparative examples in Tables 1 to 4 using the same wiping method as in Example 1.

[White residue] Comment on the white residue after cleaning the hard surface. Take a cleaned glass plate (China Taiwan Glass Industry Co., Ltd., size 30cmx30cmx().5cm). The non-woven fabric (matrix is synthetic fiber, basis weight is 40±4g/m ² , Daiwa Textile Co., Ltd.) is cut into several pieces of 20cmxl4cm size, and each of the examples in Tables 1 to 4 are added dropwise to these non-woven fabrics. With 4 mL of the detergent composition of the comparative example, a hard surface cleaning sheet (mass of the detergent composition/mass of the substrate in the non-impregnated state (dry state): 320%) was thus prepared. Use this cleaning sheet to wipe any side of the glass plate (from one edge of the glass plate to the other edge), back and forth 10 times until the liquid soaks the entire glass. Then, take a picture of the wiped glass plate, perform image processing on it (make ribs mageJ), measure the residual area of white residue on the glass plate, calculate the residual rate of white residue based on the treated area of the glass plate, and The evaluation was performed according to the following criteria.
