Description

A SOLUTION AND A CLEANING METHOD To Siamon REMITTANCE OF RELATED APPLICATIONS A related application entitled "SYSTEMS AND METHODS FOR CLEANING" of the inventor's estate of the present application, Attorney File No. M-5191 US, is filed jointly with the present application.

BACKGROUND Field of the Invention The present invention relates to cleaning and more particularly to a solution for cleaning and the uses that are derived from it.

Description of Related Techniques The formulation of cleaning solutions that have the ability to clean a wide variety of soiling, stains and contaminants from a wide variety of surfaces and materials is of significant importance. For this purpose, considerable research has been carried out in the fields of cleaning agents which have resulted in a plethora of cleaning solutions that have a wide variety of cleaning formulations. To further enhance the properties of these various cleaning formulations, components that include a wide variety of surfactants, anti-dirt agents, anti-stain agents and the like are also usually included in the final formulations. In addition, the formulations in cleaning solution have recently been introduced, which also provide antibacterial properties by virtue of containing yet another component added to these formulations that are inherently complex. However, while many of these complex compositions provide cleaning properties that are acceptable, these acceptable properties are often limited to a few specific uses. This is so, despite the many exotic and expensive components that are used. In addition, since these compositions do not usually remove odors, they often contain fragrance additives that can only serve to cover odors for a short period of time. Finally, many of these cleaning solutions have components that can be harmful to the user if they are ingested or if they come into contact with the user's skin, thus requiring protective clothing to prevent such contact. Therefore it would be of advantage to have a cleaning solution capable of cleaning a wide variety of surfaces and materials while incorporating only a few readily available components. In addition, it would be of advantage if this cleaning solution was not toxic and that it was not the cause of damage when it came into casual contact with the user's skin. Additionally, it would be of advantage if the cleaning solution had sequestration properties as it relates to a wide variety of organic materials such as oils and the like to allow the solution to be reused without re-depositing the soiled, spots and contaminants that have been removed. It would also be of advantage if the cleaning solution provides properties against dirt and stains to the surface or to the material that is cleaned by leaving a film or sheet or thin layer, protective and invisible when drying. It would also be an advantage if the cleaning solution eliminated odors without the need to add fragrance agents. Finally, it would be of advantage if the cleaning solution provided a bactericidal activity and a fungicide.

BRIEF DESCRIPTION OF THE INVENTION In accordance with the present invention, a cleaning solution that provides the aforementioned advantages is provided herein. The cleaning solution of the present invention consists essentially of a mixture of sodium bicarbonate (NaHCO3, CAS RN 144-55-8), sodium carbonate (Na2CO3, CAS RN 497-19-8), and trisodium phosphate (Na3PO4, CAS RN 10101-89-0) formulated as an aqueous solution of these components in various concentrations. The mixture of sodium bicarbonate, sodium carbonate and trisodium phosphate are present in the various concentrations mentioned above, those that have a particular molar ratio. In some embodiments of the present invention the cleaning solution is formulated to be used as a spray cleaner, to be sprayed onto a surface and the wet surface wiped with a clean cloth to remove dirt, stains and contaminants. Advantageously, upon drying, the cleaning solution of the present invention leaves a thin, invisible, protective layer or film on the surface. In some of these dew-like expressions, the cleaning solution is sprayed as a very fine spray or an aerosol to further eliminate the bad odors from the air. Advantageously, the thin, protective film or layer that is formed after drying will continue to remove such malodors after the aerosol has dispersed. In addition to eliminating odors, this thin layer and protective film provides protection against re-fouling, prevents or reduces the proportion of bacterial or fungal growth and increases the lubricity of the surface or material, thus reducing wear . In some embodiments, the cleaning solution of the present invention is formulated to be used to soak an object to be cleaned, where the solution removes dirt, stains and contaminants from the surface of the object and sequesters them to prevent Re-deposit. Such a soaking process is employed as an independent or self-cleaning method, for example, with agitation as a laundry cleaner, or as a preliminary step with or without agitation, to be followed by another cleaning step. Alternatively, in some expressions, the cleaning solution is formulated to be used with scrubbing or brushing where there are heavy accumulations of dirt or stains. In addition, in some embodiments of the present invention, a combination of one or more of these cleaning methods already described is used with one or more of the cleaning solution formulations. Finally, in all expressions of the present invention, the cleaning solution does not require rinsing after use. Thus, the cleaning solution according to the present invention cleans a surface or material and since it does not require rinsing, it provides a thin protective film or layer which adheres to the surface or material and which reduces or prevents it from becoming to mess.

DETAILED DESCRIPTION The following is a detailed description of the illustrative expressions of the present invention. As these expressions of the present invention are described, various modifications or adaptations in the methods and or in their specific structures described, may become apparent to those skilled in the art. All these modifications, adaptations or variations which are based on the teachings of the present invention, and by which these teachings have advanced or improved the technique, are considered to be within the spirit and scope of the present invention. Therefore, these descriptions should not be considered in a limiting sense since it is understood that the present invention is not limited in any way to the illustrated expressions. The present invention provides a cleaning solution for cleaning a wide variety of materials and surfaces. For example, the cleaning solution of the present invention is useful for cleaning painted surfaces such as walls, fabrics such as cotton, wool, and synthetic fabrics such as nylon and the like, tiles, glass, and the like. metal surfaces in addition to several smooth wood and leather surfaces. In addition, the cleaning solution of the present invention provides a thin and invisible protective layer or film to the surfaces or fibers of the materials that are cleaned. This thin protective layer adheres well to most surfaces and is not easily removed when scrubbed. Thus the protective layer advantageously prevents or reduces the re-soiling or re-staining of what has been cleaned and increases the lubricity of the surface or material and leads to the extraction of unpleasant odors from the surrounding environment. . Advantageously, cleaning solutions according to the present invention are formulated using a mixture of three well-known and readily available substances, sodium bicarbonate (NaHCO3, CAS RN 144-55-8), sodium carbonate ( Na2CO3, CAS RN 497-19-8) and trisodium phosphate (Na3PO4, CAS RN 10101-89-0). Each of these substances is essentially non-toxic and generally safe. Thus baking soda is commonly known as baking powder and is often used as an additive in the preparation of meals as well as used as a cleaning agent. Sodium carbonate, commonly known as baking soda or chemical yeast or salt soda, is well known as a cleaning additive or enhancer that also has the use, when found in a solution, of being a skin cleanser in cases of eczema. Finally, trisodium phosphate is well known as an agent that decalcifies water and as an ingredient in many common formulations of detergents. The cleaning solution encompassed in the expressions of the present invention is believed to achieve its advantageous properties by employing a specific molar ratio of the aforementioned components. This specific molar ratio is then formulated in aqueous solutions in a variety of concentrations. Therefore, the expressions of the present invention are aqueous solutions having various concentrations of a mixture of sodium bicarbonate (hereinafter SB), sodium carbonate (hereinafter SC) and trisodium phosphate (hereinafter hereinafter TSP) having a molar ratio of approximately 1: 2.6: 1.6. That is, for each mole of SB, 2.6 moles of SC and 1.6 moles of TSP used to prepare the cleaning solutions of the present invention In a typical or usual "full concentration" formulation, an amount of solution having a concentration The first is prepared by combining approximately 910 grams of SB, approximately 1,930 grams of SC and approximately 2,270 grams of TSP in approximately 208 liters of water. The water used is deionized water, decalcified water or water processed by a reverse osmosis (RO) system. Such typical or usual formulation of "full concentration" of the first concentration is therefore composed of an approximate 2.46% solids or active ingredients. It will be understood that the amount in "full concentration" cleaning solution described hereinabove is only illustrative and that other quantities having the same molar ratio and concentration as a percentage of solids can be easily prepared by that person of average or regular knowledge. the technique, for example 100 liters of cleaning solution of "full concentration" instead of 208 liters. Furthermore, it should be understood that while the specific molar ratio of the components described above has been found to be the most effective, other molar proportions and the like are also effective. Thus it has been found that variations of the specific molar ratio by up to 10 percent are still effective and such compositions are within the scope and spirit of the present invention. It has also been found that other concentrations of solids for the formulation described here above are also effective, for example, concentrations as high as approximately 2.7% or as low as approximately 22% have also been found to be effective and as such they are within the scope and spirit of the present invention. While "full concentration" formulations are useful as cleaning solutions, other formulations that have lower concentrations than "full concentration" formulations are also useful. They have found to be effective cleansers. Therefore a formulation that has a second concentration is prepared by diluting a solution of "full concentration" of the first concentration in about one half. Thus this formulation of "half concentration" has a concentration that is a 50% of that of the first concentration As a result, such formulation t Typical or usual is composed of approximately 1 23% solids. It should be noted that many other dilutions of the "full concentration" cleaning solution can be made and can be used advantageously to clean a wide variety of surfaces and materials. Particularly a "full concentration" formulation is determined by testing several concentrations and thus determining the "best" concentration. All these alternate dilutions are then within the scope and spirit of the present invention. For example, a cleaning solution that has a concentration of 60% (a 40% dilution of the solution having the first concentration) has been found to be advantageously useful for cleaning surfaces of games and in the vicinity of gaming tables and which are found in casinos and similar places. Such typical or usual formulation of the third concentration is composed of an approximate 1.48% solids. Finally, it will be understood that while each of the aforementioned dilutions have been characterized as dilutions of a "full concentration" solution, either could be made directly by mixing together appropriate amounts of SB, SC and TSP in the molar ratio indicated of 1: 2.6: 1.6, respectively. Although each of the above-mentioned components and of the present cleaning solution of the present invention is known, the particular mixture of these components, according to the terms of the present invention, has not yet been known. For example, in U.S. Patent No. 4,828,621"COMPOSITIONS AND METHOD FOR ANTI-STATIC PROTECTION" granted on May 9, 1989 to this inventor and now abandoned (hereinafter '621), a materially different mixture to The components of the present invention was presented. In the '621 patent this materially different mixture formed an anti-static or anti-electrostatic solution having a ratio by volume of sodium bicarbonate to sodium carbonate to trisodium phosphate of approximately 1: 2: 4 in a solution with a solids content between 4 and 16 percent. Thus, compared to cleaning solutions prepared according to the terms of the present invention, the anti-static or anti-electrostatic solution of the '621 patent is formulated with a different proportion in components and has a different concentration in solids to produce different results . In U.S. Patent No. 5,552,078, "COMPOSITION ON THE CARBONATE BASE OF A LAUNDRY DETERGENT "granted on September 3, 1996 to Carr et al. (Hereinafter '078) the three components of the present invention are taught as part of another materially different formulation. the '078 patent has both a different proportion of the three components and a generally more complex formulation with several additional components.Thus, in the' 078 patent, a powder composition composed of a surfactant is taught, at least in a 75 to a 80% by weight of sodium carbonate, approximately 0.1 to 15% by weight of sodium bicarbonate, approximately 0.1 to 2% by weight of trisodium phosphate, approximately 0.1 to 2% by weight of a polyacrylate or polymaleate and an approximate 1-12% by weight in water, where this powder composition is primarily used as a laundry detergent, therefore, in addition to the additional materials that the '078 patent teaches and which When required, the molar ratio of sodium bicarbonate to sodium carbonate to trisodium phosphate is markedly different from that of the present invention. In some embodiments of the present invention, it has been found to be additionally advantageous to formulate the present cleaning solution in a particular manner. Thus in some expressions, the indicated amount of sodium bicarbonate (SB) is added to the deionized or decalcified water of a system (RO) and stirred until dissolved. Although it is known that SB is quite soluble in water, it has been found to be advantageous to add SB to water that has been warmed to approximately 30 to 40 degrees Celsius (° C) to speed dissolution. Once the SB dissolves, the indicated amount of sodium carbonate (SC) is added to the SB solution, again stirring. By adding the SC, it will be noticed that a cloudy solution is achieved and that even after a prolonged stirring, the solution is not completely clear. Finally the indicated amount of trisodium phosphate (TSP) is added to the mixture of SB and SC, again stirring it. It should be noted that after the addition of TSP, in a short time (a few minutes) the mixture will become clear, denoting a true solution of the three components. That person with regular or ordinary knowledge of the art will realize that other methods can be used to make the cleaning solution of the present invention. For example, SC can be added to water as the first step in the preparation of the cleaning solution. In addition, it is possible to use any one of several of the various hydrated forms of various components instead of the anhydrous materials specified above. As is known, in instances where such hydrated forms are used, the amount of hydrated material is adjusted to achieve the "equivalent anhydrous weight" in order to achieve the indicated molar ratio of approximately 1: 2.6: 1.6. However, while these other methods of making or making the cleaning solution are within the scope and spirit of the present invention, the inventor has found that it is advantageous to prepare the cleaning solution in the manner described hereinbefore. In a related application, filed concurrently with the present, by the same inventor of the present, "SYSTEMS AND METHODS OF CLEANING", Attorney File No. M-5191-US, are revealed systems for cleaning objects, for example, objects stackable such as cards for games of chance, gambling chips, coins and chips in general, among others, wherein each system incorporates the cleaning solution of the present invention. This related application (hereinafter, M-5191) is hereby incorporated by reference in its entirety. As mentioned above, in some expressions and in accordance with the present invention, the cleaning solution is formulated to be sprayed onto the surface or material to be cleaned. A) Yes, as set forth in the application M-5191, a concentration of 60% of the cleaning solution is sprayed onto the gaming surface of a gaming table to slightly dampen all surfaces to be cleaned. Frequently these surfaces of games of chance, for example as it is in the tables of "Black Jack" or (Twenty-one) or "Craps" (game of chance with dice) are made of a material of felt or of imitation of felt with The appropriate play marks applied to the upper surface Once the entire surface is slightly moistened, the cleaning solution is then distributed over the surfaces using a clean cloth and any dirt or contaminants that are present are removed with a movement of slight pressure on the material or slight scrubbing on the material. Afterwards the surfaces are allowed to dry and a thin layer or film is formed. This film or thin layer is formed on the surface or around the fibers of the material and provides repellent properties of dirt as well as an increased lubricity to the surface In addition, the surface of the cleaned material is observed to become more soft to the touch and more lubricated than in the previous cleanings. Thus, the highly advantageous results are the longer periods of time between cleanings and less wear on the surface. The cleaning solution of the present invention is useful for cleaning a wide variety of surfaces using the spray method described above In addition to its utility for gaming table game surfaces, the cleaning solution can be used as a spray to clean carpets, rugs, countertops made of tiles or other natural surfaces, artificial surfaces such as Formica® or Copan®, metal surfaces such as stainless steel, glass surfaces and surfaces painted with water-based or oil-based paints such as latex or enamel. In some cases, the cleaning solution is sprayed onto the surface to be cleaned and then the surface is wiped clean of dirt and contaminants with a clean dry cloth or similar material. In other cases the cleaning solution is applied to a cloth or other applicator and the moistened applicator is used to pass it to the surface and clean it from dirt and contaminants. After cleaning a surface with the cleaning solution of the present invention, it will be noted that the clean surface acquires a smooth and lubricated feel similar to and observed for a surface painted with a high gloss finish paint. It should be noted that while the "full concentration" solution is usually compatible with most surfaces and materials, it may be advantageous to use a more dilute solution for certain materials. For example, the playing surfaces of most random gaming tables are best cleaned using the 60% concentration and for most game cards using a 50% concentration of the cleaning solution. . Thus, for most general purpose cleaning formulations, it is advisable to test a portion of the surface to be cleaned before generally cleaning to ensure that the proper dilution of cleaning solution is used. Such a prior test is well known. The cleaning solution of the present invention can also be used as a pre-soaking bath or immersion for highly soiled, stained or contaminated objects or materials. In this way, an appropriate amount of the cleaning solution of the present invention is placed in a container and the articles to be soaked are added. The dilution of the cleaning solution used as well as the soaking time are the function of the amount of dirt or stain and the particular material. Nevertheless, it has been found that for most applications a soak time between 5 to 30 minutes is indicated. For example, a highly soiled or soiled article of clothing or garment may be pre-soaked in a 50% dilution of the cleaning solution of the present invention before being washed. In this way, most if not all of the dirt or stain is removed and a standard wash cycle can be employed to result in a stain-free garment. In expressions where the amount of dirt or stain is less, it has been found advantageous to use a concentration of 60% of the cleaning solution to merely previously moisten the soiled or stained area before its standard washing. Where there is a dirt or stain or heavy contamination on a surface that has protuberances or ridges, grooves or other indentations or irregularities in the surface, it has been found advantageous to employ a combination of a pre-soaking and scrubbing to extract the dirt or stain. Thus, as mentioned in the application M-5191, highly dirty or stained casino chips are first soaked in a "full concentration" solution and then cleaned in a chip cleaning system where brushes or brushes are used to scrub the opposite sides of the casino chips. It will be understood that other surfaces than those of casino tokens can also be cleaned by combining a previous soaking with a brushed scrubbing. Thus the countertop or tile cover in a kitchen or in a bathroom room may have grooves or other indentations in which dirt or stains may accumulate, thus requiring the use of cleaning such as a pre-soaking / scrubbing method as described above. . It should be understood that in addition to accumulations of dirt or light stains, the term highly soiled or stained or contaminated also refers to dirt or stains caused by urine, grease, grape juice, chocolate, wine and the like on fabrics such as clothes, carpets or rugs. That is, dirt or stains or contaminants that usually require the use of special "stain remover" formulations as they are known to date. However, the cleaning solution of the present invention does not regularly or customarily require such "stain remover" formulations to result in a clean surface or material since some of the expressions of the present invention are formulated for use in removing. spots of such dirt or strong or heavy spots. It should further be noted that where the cleaning solution of the present invention is used in the manner of a previously known "stain remover", the "white ring" which is usually observed in other known "stain removers" is not observed. Therefore, the heavy or heavy dirt or stain or contaminant is incorporated into the cleaning solution or is sequestered and extracted rather than propagated or extended. Therefore, removing or removing such highly soiled or stained areas from garments, carpets, rugs or the like a solution in accordance with the terms of the present solution is applied to the highly soiled or stained area. In some cases the solution is applied by spray, while in other cases the solution can be applied as a previous soaking in a container, regardless of the method to be used. Once moistened, the solution is allowed to remain moistened for a few minutes before spreading and soaking or scrubbing with a clean cloth or similar item. Usually even dirt or heavier or stronger stains can be removed in this way. However, if required, a second cleaning treatment can be employed. As mentioned above, the expressions of the cleaning solution of the present invention also exhibit malodor extraction properties. Thus it has been found advantageously that when applied to clean soils or stains and malodorous contaminants, the bad smell is extracted with dirt or stain. For example, a carpet or mat smeared with animal urine is advantageously cleaned using a cleaning solution of the present invention in the form of a spray. The soiled or soiled area is lightly sprayed to soak or soak the soiled or stained area, and subsequently dried to pressure or scrubbing with a clean cloth or similar implement After removal of the dirt or stain, the area is again wetted or lightly wetted with a spray of the cleaning solution of the present invention which is allowed to dry without drying under pressure or scrubbing When drying, the odor is eliminated In addition to eliminating odors with dirt and stains, it has been found that the expressions of the present invention can be advantageously used to clean air handling systems or its growth of mold or fungus and therefore the moldy odor that accompanies it. Thus, in some expressions of the present invention, while the fan of an air handling or supply system is running at full speed, a fine mist or an aerosol of the cleaning solution of the present invention is sprayed into the air intake. In this way the aerosol is distributed through the air handling or delivery system, its ducts or channels As the cleaning solution of the present invention encompasses or encloses a mold or fungus thus preventing any continuous growth, the malodour is eliminated. Thus we have found that for the common spore of Aspergillus niger, the ratio of total spore recovery of a sample treated with the "full concentration" solution of the present invention was less than 1.5% where 100% recovery was defined as the number of spores recovered from a sample treated only with deionized and sterile water. In addition to its action to suppress the growth of microorganisms such as the fungus Aspergillus niger, the cleaning solution of the present invention also exhibits activity against a wide variety of other microorganisms. For example, the application of the expressions of the present invention to surfaces also acts as a bactericide, eliminating some of the viable bacteria by contact and essentially all the remaining bacteria by drying as a film or thin layer. This result is believed to result, at least in part, from the encapsulation properties of the film or layer that is formed when the solution is dried. In some embodiments of the present invention, a second application of the cleaning solution is applied to the cleaned surface and allowed to dry, as described herein above. It has been found that where such a second application is made, the new growth of microorganisms, for example, bacteria and fungi on the treated surfaces can be extended. The film or layer that forms when dried, is a hard, lubricated layer that has been found to be between the approximate 2 to 10 microns in thickness. It is believed that the active agents, within the cleaning solution of the present invention, combine to form an encapsulate that prevents the growth of micro-organisms and also provides an active surface that continues to eliminate odors and prevent them from go back to dirty or leave again. The presence and effectiveness of this film against the new dirt or stain can be demonstrated by placing a drop of engine oil in each of two dry wall sections, painted with a common outdoor latex paint. When a section of the wall plate has been previously cleaned with the cleaning solution, and in accordance with the present invention, the engine oil remains as a drop and when it is cleaned with cold water, it leaves no residue. In contrast, in the untreated wallplate section the engine oil spreads on contact and leaves a visible residue when it is cleaned. It should be apparent that a cleaning solution for general uses has been described, which covers only three common components, easily available. It should also be apparent that the cleaning solution of the present invention can be formulated in a variety of concentrations so as to be capable of providing cleaning for a wide variety of surfaces or materials. Furthermore, it should be apparent that since each of the components of the cleaning solution is safe and essentially composed of a material that is non-toxic, the mixture of these three components is also safe and essentially non-toxic. Additionally, it should be apparent that the cleaning solution of the present invention has sequestration properties that allow it to clean a wide variety of organic materials and properties against dirt and against stains by and through the thin film or the layer that forms when drying. It should also be apparent that the terms of the present invention possess fungicidal and bactericidal properties that extend through and through the formation of a thin film upon drying. In addition, the layer or film essentially seals the cleaned surface thus increasing the lubricity and thus extending the time between cleanings and the long life of the material due to the decrease in its wear. Finally, it should be apparent that some expressions of the present invention are useful for reducing or eliminating odors without the need to use additional agents or additives. The above described expressions of the present invention are simply intended to be illustrative and not limiting. It will therefore be obvious to those skilled in the art that various changes and modifications may be made without departing from this invention in its broader aspects. Therefore while only two specific dilutions in addition to the "full concentration" solution have been treated, it should be understood that any number of dilutions can be formulated from the "full concentration" solutions prepared and having solids concentrations from one to the other. approximately 2.46 to 2.75%. Therefore, the appended claims encompass all those changes and modifications that may fall within the true spirit and scope of this invention.
