本発明の硬質表面の洗浄方法では、前記硬質表面用液体洗浄剤組成物を、硬質表面に接触させる。
具体的には、前記硬質表面用液体洗浄剤組成物を、原液で、硬質表面に接触させる、又は前記硬質表面用液体洗浄剤組成物を、原液で、希釈せずに硬質表面に接触させる、つまり、前記硬質表面用液体洗浄剤組成物を、希釈することなく、硬質表面に接触させる洗浄方法が好ましく挙げられる。更に、前記硬質表面用液体洗浄剤組成物を、希釈することなく、デンプン汚れが付着した硬質表面に接触させる洗浄方法が挙げられる。

In the method for cleaning a hard surface of the present invention, the liquid detergent composition for a hard surface is brought into contact with the hard surface.
Specifically, the liquid detergent composition for a hard surface is brought into contact with a hard surface with a stock solution, or the liquid detergent composition for a hard surface is brought into contact with a hard surface without being diluted with a stock solution. That is, a cleaning method in which the liquid detergent composition for a hard surface is brought into contact with a hard surface without being diluted is preferably mentioned. Further, there is a cleaning method in which the liquid detergent composition for a hard surface is brought into contact with a hard surface to which starch stains are attached without diluting.
The term "contacting the liquid cleaning agent composition for a hard surface with a hard surface without diluting" means that the cleaning agent composition is intentionally diluted with water or the like and then not brought into contact with the hard surface. For example, the liquid detergent composition for a hard surface may be brought into contact with a hard surface to which water droplets or the like are attached, or the liquid detergent composition for a hard surface may be brought into contact with a hard surface and then water droplets may be attached to the hard surface. In this case, it can be understood that the liquid detergent composition for a hard surface is brought into contact with the hard surface without being diluted.
In the present invention, the undiluted solution of the liquid detergent composition for a hard surface is adhered to a hard surface as it is, that is, without changing the composition under the specific conditions. For example, the liquid detergent composition for a hard surface is brought into contact with a hard surface to which starch stains are attached without adhering to a water-containing sponge. After contacting the hard surface, the composition of the liquid detergent composition for the hard surface may vary. That is, after contacting the hard surface, the composition of the liquid detergent composition for the hard surface may be diluted or concentrated.

水で希釈することなく用いる場合には、該洗浄剤組成物は、前記洗浄濃度で（Ａ）成分、（Ｂ）成分又は（Ａ−Ｂ）成分を含有し、ｐＨ５以上１０以下である。
尚、水で希釈する場合は、１を超えて１００倍以下、２倍以上１０倍以下程度の水で希釈して用いることが好ましい。
However, a concentrated composition containing the components (A) to (C) (or the components (AB) and (C)) of the present invention, water and an optional component is prepared, and the concentrated composition is prepared at the time of use. The material may be diluted with water to prepare the liquid detergent composition for a hard surface of the present invention so as to meet the above specific conditions, and may be brought into contact with the hard surface. That is, the hard composition of the present invention is obtained by diluting a concentrated composition containing the components (A) to (C) (or the components (AB) and (C)), water and optional components of the present invention with water. A method for cleaning a hard surface may be used in which a liquid detergent composition for a surface is prepared and the liquid detergent composition for a hard surface is brought into contact with a hard surface without being diluted.
That is, in the cleaning method of the present invention, a liquid cleaning agent composition for a hard surface containing (blended) components (A) to (C) (or components (AB) and (C)) and water. The composition is hardened under the conditions that the component (A) is 1 mM or more, the component (B) is 1 mM or more, and the pH is 5 or more and 10 or less, without diluting with water or by diluting with water. It is a method of cleaning a hard surface that comes into contact with the surface.

機械力をかけずに放置するとは、例えば、組成物の接触以外に、洗浄のための意図的な操作を行わないことである。例えば、洗浄を意図しない振動が硬質表面に伝わることなどは、機械力をかけずに放置すると理解できる。
浸漬して放置した後は、通常、水ですすぐ。すすぐ際は、手などで機械力（物理的力）を掛けてもよく、単に水流ですすいでもよい。
Further, as a method for cleaning a hard surface of the present invention, there is a cleaning method in which a hard article is immersed in the liquid detergent composition for a hard surface and then left without applying mechanical force (without applying). That is, there is a cleaning method in which the composition is immersed in the composition without using a flexible material such as a sponge, fingers, or the like, and left as it is without applying mechanical force. This is suitable for cleaning parts that are out of reach of hands and tools and details that are difficult to reach.
Leaving without mechanical force means, for example, no intentional operation for cleaning other than contacting the composition. For example, it can be understood that vibrations that are not intended for cleaning are transmitted to a hard surface if left unattended without applying mechanical force.
After soaking and leaving, usually rinse with water. When rinsing, mechanical force (physical force) may be applied by hand or simply rinsing with a stream of water.

また、本発明の硬質表面の洗浄方法は、前記硬質表面用液体洗浄剤組成物を、硬質表面に接触させた後、機械力をかけず（付与せず）に放置する洗浄方法が挙げられる。つまり、スポンジ等の可撓性材料や手指等を用いることなく接触させ、機械力をかけずにそのまま放置する洗浄方法が挙げられる。これにより、手や道具の届かない部位や届きにくい細部の洗浄に好適である。
機械力をかけずに放置するとは、例えば、組成物の接触以外に、洗浄のための意図的な操作を行わないことである。例えば、接触させた組成物が硬質表面を自然に流下することや、洗浄を意図しない振動が硬質表面に伝わることなどは、機械力をかけずに放置すると理解できる。
放置した後は、通常、水ですすぐ。すすぐ際は、手などで機械力（物理的力）を掛けてもよく、単に水流ですすいでもよい。
放置する時間は、前述の浸漬時間と同じ範囲が好ましい。
Further, as a method for cleaning a hard surface of the present invention, there is a cleaning method in which the liquid detergent composition for a hard surface is brought into contact with the hard surface and then left without applying mechanical force (without applying). That is, there is a cleaning method in which a flexible material such as a sponge, a finger, or the like is brought into contact with each other and left as it is without applying mechanical force. This is suitable for cleaning parts that are out of reach of hands and tools and details that are difficult to reach.
Leaving without mechanical force means, for example, no intentional operation for cleaning other than contacting the composition. For example, it can be understood that the contacted composition naturally flows down the hard surface, and vibration unintended for cleaning is transmitted to the hard surface when left without applying mechanical force.
After leaving it, it is usually rinsed with water. When rinsing, mechanical force (physical force) may be applied by hand or simply rinsing with a stream of water.
The leaving time is preferably in the same range as the above-mentioned immersion time.

[Evaluation of starch stain cleaning property]
150 g of Koshihikari from Akita was taken and cooked with 200 g of water in a rice cooker (manufactured by Zojirushi Mahobin Co., Ltd., model number NP-GE05) in white rice mode. The cooked white rice was rubbed evenly on one side of a pre-weighed test piece (material SUS304, 25 mm (horizontal) x 70 mm (vertical) x 1 mm (thickness), mass x) so that no rice grains remained. The test piece rubbed with white rice was dried for 30 minutes, confirmed to be solidified, and weighed (y). Six pieces of this test piece were set in a leanut test holder, 700 mL of each liquid detergent composition shown in Table 1 whose liquid temperature was adjusted to 25 ° C. was poured into a 1 L glass beaker, and the test holder was immersed therein. , The leanut tester was spun at 200 rpm and washed for 20 minutes. After washing, the test holder after washing was immersed in another 1 L glass beaker containing 700 mL of water (hardness 3 ° dH), and the leanut tester was rotated at 200 rpm for rinsing for 3 minutes. .. The test holder was removed from the water, each test piece was dried overnight, confirmed to be solidified, and weighed (z). The cleaning rate of each test piece was calculated from the following formula, and the average value of the cleaning rate of 6 test pieces is shown in Table 1.
Cleaning rate (%) = {(y)-(z)} / {(y)-(x)} x 100
