However, the present invention is not limited thereto, and the gist of the present invention is not limited thereto. In the drawings, the same elements are denoted by the same reference numerals. In addition, the positional relationship such as up, down, left, right, etc. will not be specified. Insofar as possible, the positional relationship shall be based on that shown in the drawings. Furthermore, the dimensional ratios of the drawings shall be in accordance with the ratios shown in the drawings. It is not limited to this.

The cleaning sheet has a chemical solution release rate of 75 mass % or more, and the contact angle of the chemical solution is acrylonitrile 60% to tri-butadiene-styrene copolymer (hereinafter simply referred to as "ABS resin"). The cleaning sheet according to the present embodiment is effective in removing dirt adhered to resin members. The drug release rate is measured by the method described later, in which the nonwoven fabric is impregnated with the drug solution and centrifuged. This is a numerical value that represents the amount of chemical solution that is separated when the cleaning sheet according to this embodiment is released. When the surface of the object to be cleaned is wiped with the nonwoven fabric, the chemical solution is absorbed into the nonwoven fabric because the chemical solution release rate is 75% by mass or more. The chemical solution seeps out and dissolves dirt on the surface of the object being cleaned. By having a predetermined contact angle, it is particularly effective at removing resin stains that are difficult to wipe off.
[0012] The chemical solution desorption rate of the cleaning sheet according to this embodiment is preferably 80% by mass or more. More preferably, the content is 85% by mass or more, and further preferably, 90% by mass or more.

The total mass of the nonwoven fabric after centrifugation is M 2 (g) was measured, and the result was calculated by the following formula (1 ) to calculate the drug desorption rate (%). Drug desorption rate = (M 1 -M 2 ) / 3 × 100 (1)

By using the cleaning sheet according to this embodiment to wipe the surface of an object to be cleaned, the chemical solution does not seep out. The amount of chemicals removed is measured by rotating the cleaning sheet at 2000 rpm. The cleaning sheet was centrifuged at 40°C for 3 minutes to remove the impregnated chemical solution, and the mass change of the cleaning sheet was calculated. This is the value.

The cleaning member holding part 2 of the cleaning tool 1 is detachably attached to the cleaning member holding part 2 of the cleaning tool 1. is as follows:
[0042] FIG. 2 is a plan view showing a schematic configuration of the cleaning member 11 according to the present embodiment. The cleaning member 11 is, for example, made of the nonwoven fabric of the cleaning sheet according to this embodiment. The nonwoven fabric is impregnated with the above-mentioned chemical solution. The cleaning member 11 is, for example, a long nonwoven fabric. The outer periphery of the bag is joined at a joint 114, leaving an opening 113.

[0044] A user grasps the gripping portion 3 and brings the cleaning member holding portion 2, to which the cleaning member 11 is attached, into contact with an object to be cleaned. The cleaning is performed by pressing the cleaner against the contact surface. An air conditioner will be used as an example of the object to be cleaned. The air outlet of the air conditioner is easily contaminated, but the opening is narrow and it is difficult to insert cleaning tools inside, so it is difficult to clean it. Since the cleaning tool 1 has a plate-shaped cleaning member holding part 2, the cleaning tool 1 is difficult to clean with the air conditioner. In addition, air conditioner vents are curved to control the airflow. Therefore, even if a cleaning tool gets inside the air outlet, it will not stick to the air outlet.
