関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent and a cleaning method for a pressure type spray cleaning machine used in a coin car wash, a non-brush gate type car wash, a vehicle body wash, a building wash, a dish wash and the like.

Description of the Related Art Usually, in washing with a pressure type spray washing machine, water, a detergent containing various surfactants in water, or a detergent containing an alkali builder added thereto is used. However, under the present circumstances, it is impossible to remove stains that can be removed immediately by rubbing lightly with the fingertip. For this reason, although a strong alkaline detergent containing a large amount of an alkali builder is applied to the surface of the article to be washed to raise the dirt and then the surface is washed with a high pressure spray, sufficient detergency cannot be obtained.

欠点を有している。However, the above-mentioned cleaning agents and cleaning methods have insufficient cleaning power, and a large amount of strong alkaline components are drained, which is a serious problem in terms of pollution. In order to prevent this, a wastewater treatment facility that can be drained after neutralization is required, resulting in a large amount of equipment cost and the need to fix the washing machine. On the other hand, as another cleaning method, inorganic substances, resins, and other powders that are insoluble in water are blended in the cleaning agent of the pressure-type spray cleaning machine, and sprayed onto the surface to be cleaned so that the particles have a physical action. It is known that the cleaning power can be remarkably increased, but after cleaning, powder that does not dissolve in water adheres to and accumulates on the cleaning product and the vicinity of the cleaning product, making it impossible to treat them. The problem is that it is not widely used. Further, in the proposal of Japanese Unexamined Patent Publication No. 6-182262, there is considered a method of washing away dirt and dust of a washing object by using a shock wave generated by a bubble generating device for bursting bubbles. However, when the above-mentioned bubbles are jetted at high pressure, they escape before reaching the cleaning object, and at the point when they reach the cleaning object, the bubbles disappear, and the shock wave due to the bursting of the bubbles cannot be sufficiently obtained, so the desired cleaning power is obtained. It has the drawback that it cannot exhibit.

The cleaning agent and the cleaning method are proposed. The cleaning agent in the present invention is water or a general cleaning liquid in which carbon dioxide gas is dissolved or contained when cleaning an object to be cleaned by high-pressure jetting. A method of dissolving or containing carbon dioxide gas in water or a general cleaning liquid from a gas cylinder or dry ice, and during the neutralization reaction of hydrogencarbonate salts such as sodium hydrogencarbonate, potassium hydrogencarbonate and ammonium hydrogencarbonate with inorganic acids and organic acids There is a method of dissolving or containing carbon dioxide in water or a general cleaning liquid. When the cleaning agent according to the present invention is injected under high pressure, carbon dioxide is dissolved in water or a general cleaning solution at the discharge port even if a solution in which carbon dioxide is dissolved or contained in water or a general cleaning solution is sprayed. It can be added and sprayed. Alternatively, the carbon dioxide gas may be dissolved or contained in water or a general cleaning liquid at the place where the liquid comes into contact with the cleaning product.

この結果現状の高圧スプレーでは除去できなかった業界
で言われている「最後の一膜」の汚れを効果的に除去で
きることとなる。In the present invention, unlike carbon dioxide, carbon dioxide dissolves well in water or a cleaning liquid, so that carbon dioxide can be retained until it reaches the object to be cleaned, and bubbles of carbon dioxide gas burst or break on the surface of the object to be cleaned. It is possible to obtain a sufficient shock wave.
As a result, it is possible to effectively remove the "last film" stain, which is said in the industry, which could not be removed by the current high pressure spray.

りせず汚れを除去することができることとなる。Water is the best solution for dissolving or containing carbon dioxide in the present invention, but if necessary, a cleaning solution containing a surfactant as a main component may be used. However, when the concentration of the surfactant is high, bubbles of carbon dioxide gas are stabilized and are less likely to break or burst, so the minimum required concentration is suitable. As described above, when the high-pressure spray cleaning is performed using the cleaning agent of the present invention, it is almost completely pollution-free, and the dirt can be removed without damaging or attacking the cleaning object.
