2. Description of the Related Art Conventionally, black spots of oily smoke caused by cigarette tarnishing and cooking, dirt on walls and ceilings due to black spots caused by indoor circulation of inhaled substances from outside air due to use of an air conditioner, or refrigerators It was extremely difficult to clean the wall with black spots behind it using only ordinary detergent.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for easily cleaning stains on a wall surface or a ceiling surface which has been stained by using a cigarette dust or an air conditioner.

[0004]

Here, the inventor of the present invention has an oxygen-based bleaching agent powder containing sodium percarbonate in a weight ratio of 1 to 35% by weight of a hydrogen peroxide solution of 1.33 to 3.9.
A powder consisting of 9 and 30% magnesium hydroxide and 70% slaked lime was mixed with 0.87 to 2.61 and mixed with 6 powder.
A solution diluted with hot water of 0 to 70 ° C. was used as a washing solution,
Apply the sponge to the cloth surface within about a minute, leave it for a predetermined time, wash it off by vacuum suction while spraying water on the cloth surface, and finally wipe it dry with a blank to finish the cloth cleaning I found something I could do.

It has been found that hot water has little effect below 60 ° C., and it is found to be effective if the dilution ratio with hot water at 60 ° C. to 70 ° C. is 3 to 20 times depending on the degree of contamination. If the degree of dirt is high, use it in a thick state.

[0006] Further, the cleaning effect is further improved by inserting a cleaning step of applying steam at 70 to 80 ° C to the cloth surface and extruding dirt after the cleaning liquid is applied and allowed to stand.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The cloth to be cleaned in the present invention is made of vinyl, paper, fiber or the like. In addition, the present invention can be applied to a plastic surface.

The oxygen bleaching powder containing sodium percarbonate used in the present invention has been conventionally sold as a bleaching agent for clothing, and is composed of sodium percarbonate, a bleaching activator and an alkali containing carbonate. And a surfactant such as sodium alkyl sulfate sodium ester and polyoxyethylene alkyl ether, an enzyme for decomposing dirt, a water softener, a stabilizer and the like.

A commercially available hydrogen peroxide solution having a concentration of 35% by weight is used. Powders consisting of 30% magnesium hydroxide and 70% slaked lime are readily available as commercial products in the form of mixtures.

For cleaning the cloth, the oxygen bleaching powder 1 containing sodium percarbonate at a weight ratio of 1
5% by weight of hydrogen peroxide 1.33 to 3.99 and 30%
Of magnesium hydroxide and powder of 0.87 to 2.61 consisting of 70% slaked lime, diluted with hot water of 60 to 70 ° C. to 3 to 20 times according to the degree of dirt (dirt of dirt) If the degree is high, use it in a concentrated state) as the cleaning liquid. Since it has been found that the duration of the effect as the cleaning liquid is within about 10 minutes, the cleaning liquid is applied to the cloth surface using a sponge within the time. It is necessary to leave for more than 10 minutes after application, and if the contaminated part is conspicuous, apply steam at 70-80 ° C to extrude the dirt that is difficult to remove, and then suction under reduced pressure while spraying water onto the cloth surface. Rinse and finally wipe dry. If the dirt is severe, the above clean
It can be solved by repeating it several times.

Mixing of a 35 wt% hydrogen peroxide solution (B) and a powder (C) composed of 30% magnesium hydroxide and 70% slaked lime with respect to an oxygen bleach powder containing sodium percarbonate (A). The weight ratio is usually A: B: C =
1: 1.33: 0.87 is sufficient, but when there are many cigarette tarnishes, the ratio is 1: 2.66-3.99 (the more dirt, the larger): 0.87 If there is a lot of dirt, it is better to set the ratio to 1: 1.33: 1.74 to 2.61 (the larger the more dirt, the larger).

After the cleaning liquid is applied to the cloth surface with a sponge, the contaminants that are partially conspicuous are cleaned by applying steam at 70 to 80 ° C. The use of steam is intended to enhance the bleaching effect of the cleaning liquid. The purpose is to wash away dirt that has entered the uneven eyes in the thick cloth having the unevenness. For cleaning using steam, a commercially available steam cleaner such as Karcher 1501 manufactured by Karcher Japan K.K.
And 1201 can be used.

When suction is performed under reduced pressure while spraying water on the cloth surface, spot rinsers 14 manufactured by Zao Sangyo Co., Ltd. and carpets manufactured by Karcher Japan Co., Ltd. are commercially available as a rinser vacuum system. Rinse cleaner Puzzi10
It can be performed in a short time using 0 or the like.

It can be said that the cleaning liquid described above has a great effect of using a powder composed of 30% of magnesium hydroxide and 70% of slaked lime. In other words, simply adding 35% by weight of hydrogen peroxide solution to the oxygen-based bleach powder containing sodium percarbonate only causes significant generation of active oxygen and causes strong odor and eye irritation, and the working environment is extremely poor. It required proper human protection equipment. However, when a powder composed of 30% of magnesium hydroxide and 70% of slaked lime was added to these, stable fine bubbles were formed, odor and eye irritation disappeared, and the cleaning effect was rather improved.

[0015]

The present invention will be described more specifically with reference to the following examples. Since there was a limit on the washing time (about 10 minutes) for 100 m ² of vinyl cloth, washing was performed every 25 m ^{2 in} four times. In one batch, it was used as an oxygen-based bleach powder and was supplied by Kao Corporation as Wide-Hita-46.
62.15 g of hydrogen peroxide solution having a concentration of 35% by weight based on 5 g
And a mixture of 40.5 g (equivalent volume) of powder consisting of 30% magnesium hydroxide and 70% slaked lime are diluted 5-fold with hot water at 65 ° C. to obtain a cleaning solution.

For the work, it is necessary to wear rubber gloves and protective glasses for security, and to wash the rubber gloves with water after the work. The obtained cleaning liquid is applied to the cloth surface slowly and uniformly with a sponge, and reciprocated two or three times, so that each cleaning step is completed within about 10 minutes. After standing for 13 minutes, the cloth surface is cleaned by spraying a steam at 70 ° C. with Karcher 1501 manufactured by Karcher Japan K.K. as a steam cleaner. Then, using a spot rinser 14 manufactured by Zao Sangyo Co., Ltd. as a commercially available rinser-vacuum system, suction was performed under reduced pressure while spraying water onto the cloth surface. Finally, the cloth was wiped empty and repeated four times. -Le Cross 10
0 m ² could be finely finished.

[0017]

According to the present invention, it is possible to easily clean cloth to which cigarette tar and the like are adhered. In addition, since the work of vacuum suction while spraying water onto the cloth surface can be performed by a mechanical method before the empty wiping finish, the working time can be shortened, and the finish can be finished without unevenness.
