Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cleaning a sink with a liquid composition, and more specifically, a method for removing cloudiness of a sink in a kitchen sink (including a kitchen table and the surroundings of the sink; The present invention relates to a method, a method for removing scales, and a method for cleaning a sink with a liquid composition suitable for a method for preventing scales from adhering.

[0002]

2. Description of the Related Art Generally, kitchen sinks have oil stains on the sink surface such as a stainless steel surface, and stains such as cloudy weather (a dull, cloudy appearance) and water stains (the appearance of a wrinkle after a drop of water). is doing. Dirt on these sink surfaces
It is a composite of organic stains derived from foods such as proteins and oils (oils and fats), and inorganic stains such as water spots produced by evaporation of water droplets after use of a sink or washing. In particular, stains on water spots are derived from hardness components of tap water and are aggregates of scale particles such as SiO ₂ and CaCO ₃ .

With respect to oil stains, stains and scale stains on these sinks, conventional commercially available detergents containing a surfactant as a main component are effective in removing stains due to oil and fat components such as oil. However, there is a problem in that there is no effect on the removal of inorganic dirt, which is one of the causes of sink dirt, and in particular, the removal effect of calcium and silicon, which are the causative components of water spots, or the effect of removal is insufficient. Further, when trying to forcibly remove water stains with various cleansers, cream cleansers, scrubbers, etc., there is a problem in that the sink is damaged and the coating film is scraped off.

On the other hand, Japanese Patent Laid-Open No. 6-33096 discloses that
When washing glass bottles for recycling beer bottles, sake, soft drinks, etc. with a washer, the insoluble silicic acid scale formed by the silicic acid component eluted from the glass bottles adhering to the glass surface during washing and drying. In order to prevent whitening (white turbidity stain) due to the formation of etc., an alkali metal hydroxide such as caustic soda, a sequestering agent, propylene glycol, glycerin, ethylene glycol or sorbitol that keeps the glass bottle surface moisturized for a long time. And the like, a glass cleaner for preventing whitening by a washing machine containing a polyhydric alcohol such as JP-A-6-172 is disclosed.
No. 788, a specific sugar ester-based surfactant,
Anionic surfactant having a specific functional group and 1 to 6 carbon atoms
Disclosed is a liquid detergent composition containing a specific amount of each of the monohydric or polyhydric alcohols described above and having a mild and moisturizing feel on the skin.

However, the above-mentioned Japanese Patent Laid-Open No. 6-33096.
The glass cleaning agent containing an alkaline cleaning component as a main component described in JP-A No. 2003-187242 is intended to prevent the whitening of a glass bottle by a washing machine, and the whitening of the glass bottle and the cloudiness or scale of the sink of the present invention. The stains and the like are different in the generation place, the causative substance, the content thereof, and the like, and are different from the present invention in the intended use / purpose, problem, and mechanism of action. Further, monohydric or polyhydric alcohols having 1 to 6 carbon atoms such as ethanol, glycerin, and ethylene glycol contained in the liquid detergent composition disclosed in JP-A-6-172788 are mild and moisturized on the skin. The present invention is different from the sink of the present invention for preventing or removing stains such as cloudy water and water stains in the purpose of use, problems, and mechanism of action. Furthermore, even if these glass cleaners or liquid cleaner compositions are used, as described above, the purpose of use and the like are different, so that it is not possible to remove stains such as cloudiness and scale of the sink, and However, its preventive effect is also insufficient.

Further, in the present invention, in addition to oil stains on the sink, why the sink is clouded, the cloud is prevented, the scale is removed,
It can be inferred as follows whether or not water stains can be prevented easily and easily. That is, it is already present in the sink by either adhering the liquid composition of the above-mentioned composition to the sink and then rubbing it with the solid, or by previously adhering the liquid composition of the above-mentioned composition to the solid and then rubbing the sink. Cloudy, scale, etc., due to the components obtained through the hydrolysis and reduction process of natural polysaccharides contained in the liquid composition,
When the scale particles such as SiO ₂ and CaCO ₃ derived from water spots are loosened loosely and densely, facilitating easy cleaning to remove fog and scale, and when there is no fog or scale on the sink. Further, if the sink is cleaned by the above method, the aggregation of scale particles such as SiO ₂ and CaCO ₃ is alleviated due to the reduction of the surface tension, and the cloud of the sink and the deposit of the scale caused by the evaporation of the water droplets are prevented. It is presumed that this can be done.

In the cleaning method of the present invention, if the sink is cleaned by the above method after the cooking work in the sink or the like, it is possible to easily and easily remove the cloudiness already existing in the sink and / or prevent the scale. In addition, if the sink does not have these fog or scale, or if the fog or scale has been removed by the above method or the like, and if the sink is further cleaned by the above method, it is possible to prevent the fog from occurring in the sink, Can be prevented. Further, in the present invention, in addition to the above-mentioned cleaning method, the liquid composition of the above-mentioned composition can also serve as normal washing of vegetables / fruits, tableware, cooking utensils, etc., whereby the tableware to the sink can be washed cleanly. . Furthermore, if the liquid composition contains an antibacterial / sterilizing component, it is possible to disinfect a solid substance such as a sponge body used for rubbing the sink.
