In addition, a porous structure (for example, a sponge-like structure) obtained by dispersing air bubbles in a resin can also be used as the substrate.

Further, a cleaning method of wiping a hard surface using a cleaning article impregnated with the liquid cleaner composition for hard surface according to the present invention is preferable for light cleaning of the hard surface from the viewpoint of workability of the cleaning operation. The cleaning article impregnated with the hard surface liquid detergent composition is obtained by pre-impregnating the substrate with the detergent composition, or the dried substrate is impregnated with the hard surface liquid detergent composition immediately before use. Any of the following can be used. The cleaning article impregnated with the hard surface liquid cleaning composition may be used by being attached to a mop-like cleaning tool, or may be used for direct cleaning by hand.

When the hard surface liquid detergent composition is previously impregnated, the impregnation rate of the hard surface liquid detergent composition is determined by the weight of the substrate [i.e., the non-impregnated state (dry state) of the substrate] from the viewpoint of cleanability. 100% by mass or more is preferable, 150% by mass or more is more preferable, and 1000% by mass or less is preferable, and 400% by mass or less is more preferable, and 350% by mass. It is further more preferable that the content is% or less. If the impregnation rate is 100% by mass or more, sufficient cleaning performance against stains and dirt can be obtained.

Place the absorbent cotton (Curelet 4 x 4 cm ² made by Kawamoto Sangyo Co., Ltd.) cut to the size of the model soil on the slide glass to which this model soil is attached, and drop 1 mL of each hard surface liquid detergent composition After leaving for a predetermined time described in Table 1, the entire surface of the slide glass was rubbed with a light force (about 200 g weight) for 5 times back and forth. After that, the slide glass was thoroughly rinsed with ion-exchanged water, and then the detergency was judged based on the following criteria. As a specific method of evaluation criteria, slide glass without stain application, slide glass before cleaning after cleaning, slide glass after cleaning are photographed under the same shooting conditions such as brightness, and each image is obtained from the obtained images. The gray scale of the slide glass was measured. The pre-wash slide glass had a wash rate of 0%, and the non-stained slide glass had a wash rate of 100%, and the post-wash plate wash rate was calculated. The image processing software ImageJ 1.47v was used for gray scale measurement.

(2) Evaluation of rinseability after washing 24mL of each cleaning solution on a 100 x 120 cm ² bathroom floor, after rubbing 70 times with a sponge, rinse with a tap water shower, and the time until foam disappears completely, the following criteria It evaluated by. The temperature of tap water at the time of rinsing was 30 ° C., and the flow rate was constant at about 143 mL / sec.
Foam disappears within 1:25 seconds and rinse is complete.
2: The bubbles do not disappear even after 25 seconds.
3: The bubble disappears for more than 30 seconds.

(3) Practical evaluation of detergency The absorbent cotton was cut into 2 × 2 cm ² on the surface of a stainless steel plate with stainless steel plate attached for 1 month in a kitchen sink of a real household, and then cured (curelet 4 × 4 cm ² Place the Kawamoto Sangyo Co., Ltd.), was added dropwise a hard surface liquid cleaning compositions 1mL of example 2 and allowed to stand for 20 minutes, reciprocating the entire surface of the faucet surface 5 times small force (approximately 200g weight) I rubbed it. Thereafter, the plate surface was rinsed thoroughly with deionized water. The hard surfaces of the stainless steel plate before and after cleaning were photographed under the same imaging conditions such as brightness. The photograph before washing is shown in FIG. 1, and the photograph after washing is shown in FIG.

Comparing FIG. 1 and FIG. 2, after scaly-like blister stains adhering before cleaning are washed using the liquid surface cleaning agent composition for hard surface of Example 2, scaly-like blister stains are mostly It can be seen that it has been removed.
