The liquid detergent composition for hard surface is brought into contact with the hard surface to which the dye stain adheres or penetrates without diluting. This means that after the detergent composition is intentionally diluted with water or the like, the dye stain is removed. Avoid contact with hard surfaces that have adhered or penetrated. For example, when the liquid cleaning composition is brought into contact with a hard surface to which water droplets or the like are attached, or after the liquid cleaning composition is brought into contact with the hard surface, water drops are attached to the hard surface. It can be understood that the cleaning composition is brought into contact with the hard surface to which the dye stain has adhered or penetrated without being diluted.

  In the present invention, the stock solution of the liquid detergent composition for hard surface is adhered to the hard surface as it is, that is, without changing the composition.

(1) Dye washing test One side of a polypropylene substrate (width 25 mm, length 75 mm, height 1.0 mm, hereinafter referred to as PP substrate) was polished with 500 mesh sandpaper to obtain a polished PP substrate. Model dye-stained PP substrate in which 250 μL of hexane solution of β-carotene (manufactured by Wako Pure Chemical Industries, Ltd.) adjusted to 0.2 mM is evenly applied to the polished surface of the polished PP substrate, dried, and infiltrated with β-carotene It was created.
100 g of the liquid detergent composition for hard surface was put into a 100 mL container (glass wide-mouth standard bottle No. 11), and then one model dye-stained PP substrate was leaned into the container and brought into contact with the composition. At this time, the part to which the dye stain of the model dye stain PP substrate was adhered was all immersed in the composition in the container.
After leaving the model dye-stained PP substrate immersed in the liquid detergent composition for hard surface in the container for the time shown in Table 1, the model dye-stained PP substrate is taken out and rinsed with tap water for 1 minute. , Dried.
Using a color difference meter (Spectrophotometer SE6000, manufactured by Nippon Denshoku Industries Co., Ltd.), the b * values of the polished PP substrate, the model dye soiled PP substrate before cleaning, and the model dye soiled PP substrate after cleaning were measured. The b * value was measured at 3 points per substrate, and the average value was used to calculate the dye cleaning rate based on the following formula. The measurement of the dye washing rate was repeated twice, and the average value of the two times was shown in Table 1 as the dye washing rate.
Dye cleaning rate (%) = (b * value of model dye dirt PP substrate before cleaning−b * value of model dye dirt PP substrate after cleaning) / (b * value of model dye dirt PP substrate after cleaning) −polishing PP substrate b * value) x 100
