Description
CLEANING COMPOSITION
FIE~D OF THE INVENTION
The present invention relates to cleaning compositions, and more particularly, the present invention relates to a cleaning composition that cleans mold, mildew, algae, grease, and stains from a variety of surfaces including natural wood, stucco, concrete, and other hard surfaces.
BACRGRo~ND OF THE INVENTION
Numerous cleaning products are currently being marketed in order to clean different types of wood which are used to make decks, fences, siding, and so forth. Examples of products on the market which are sold for these purposes include MILDEW CHEK, DECK B~IGHT, JOMAR, CEDAR CLEAN, and WOLl~AN DECK BRIGHTEN~R. All of the these products require some type of scrubbing or brushing in order to achieve the stated purpose. Further, many of these products require mixing or measuring of some sort and therefore are very susceptible to being mixed improperly and being ineffective or being an environmental and safety hazard. Many of the products also harm plants, fish, animals, or birds which can destroy the landscaping around and/or wild life around the structure being cleaned.
As further background to the present invention, several different acids can be used to clean various types of wood, concrete, and other outside surfaces. However, no single acid will clean mold, mildew, algae, organic stains, and remove dirt without harming one or all of a variety of surfaces to be cleaned.
Also, any one of several products currently being marketed to clean outside surfaces recommend brushing, scrubbing, mixlng 2 '~
with other ingredients and/or mention incompatibility with some surfaces.
Additionally, chlorine bleach is often used to clean outside surfaces. However, although it will do a good job, even the manufacturers of chlorine bleach do not recommend it for this use because used alone, the bleach will dry wood too much and cause the knots to shrink and fall out. It will also cause wood to cup when exposed to direct sunlight.
Finally, there are many products that consist of poisonous petroleum based chemicals that will kill mold, mildew, fungus, and algae, but there are none with a combination and compatibility of chemicals that are safe ana environmentally degradable.
SUM~RY OF TME INVENTION
Accordingly, one object of the present invention is to provide a cleaning composition that will clean a variety of outdoor surfaces in addition to wood with absolutely no scrubbing or brushing.
It is also an object of this invention to provide a cleaning composition that can be sold full strength, so that mixing or measuring is not required, thereby leaving room for improper mixing resulting in ineffectiveness or being an environmental and safety hazard.
It is also an object of this invention to provide a cleaning composition which can be sold full strength and maintain maximum performance while at the same time being so mild that when used as directed will effectively clean without harming the environment such as plants, fish, animals, or birds.
$ :~
It is an even further object of the present invention to provide a cleaning composition for outdoor surfaces which is ., ; degradable and quickly breaks down into inert materials.
These and other objects have been achieved by providing a S composition comprising:
(A) about 0.1 to about 20 percent by volume of a surfactant that is miscible with water and compatible with chlorinated bleach solutions;
(B) about 0.1 to about 8 percent by volume of one or more alcohols selected from the group consisting of a primary, secondary, tertiary, and quaternary alcohol i:
which is compatible with chlorinated bleach solutions;
(C) about 0.025 to about 0.35 percent by volume of a 100 percent chlorinated bleach solution; and (D) the balance being water.
In a preferred embodiment, the alcohol is isopropyl alcohol and the bleach solution is a 100 percent solution of sodium . .
hypochlorite or potassium hydrochlorite.
DET~ILED DESCRIPTIO~ OF THE INVENTION
` 20 The above-described composition is new in the industry :":, ~;~ because it is the only composition formulated with a combination of chemicals that are considered to be mild household cleaners but works as fast as most dangerous acids. In actual field tests, the presently claimed composition dramatically out-performed every product that could be found available in and was sold in major hardware, paint, and marine stores in the United ; States.

Further, the combination of ingredients is unique in that the chlorinated bleach solution will clean mold, mildew, fungus, algae, and other stains on outdoor surfaces, but at the same time the surfactant or surfactants act as a buffer in that they combine with and retard the harshness of the chlorinated bleach solution and enhance the action of the chlorinated bleach solution by emulsifying organic oils and any animal fatty acids and dirt residue. The surfactants are also penetrants that will actually penetrate porous surfaces and help lift the foreign matter to the surface for easy removal. The alcohol serves two purposes: first, it helps the chlorinated bleach to slightly raise the grain in wood so the wood will more easily release the foreign matter and cleaning action can take place with no labor, and second, it also acts a drying agent on the emulsified organic oils so that they tend to thicken and stick together for easier removal. With this combination of ingredients, the pressure from the averaye garden hose is all that is needed to cause the surface to be cleaned. This action is unsurpassed in cleaning , 'Z; .
and preparing surfaces and especially wood, for painting, staining, or sealing.
According to the present invention, tha surfactant can be any surfactant that is miscible with water and compatible with concentrated chlorinated bleach solutions. The phrase "compatible with concentrated chlorinated bleach solutions" means that the surfactant and chlorinated bleach solutions are soluble in each other without reacting or changing their chemical composition. The surfactant must be suitable for storage with hypochlorite solutions without loss of its cleaning ability and without reaction.
The surfactant emulsifies the oils and dirt impregnated in the wood or surface being cleaned as well as any perfume or odorant oils added to the inventive composition. Further, the surfactant emulsifies undesirable materials in and on the surface being cleaned and helps remove these undesirable materials such ,"
as oxidized oils and dirt. The surfactant also serves as a buffer to prevent raising the wood grain by the hypochlorite solution.
; Preferably, the surfactant is an ethoxylated and/or . -., ~i sulfonated carbon chain and an amine oxide and/or lauryl betaine.
. .
Specific examples of such surfactants suitable for use in the present composition include a lauryl dimethyl amine oxide, a lauryl betaine, an ethoxylated hydrogenated tallow amine, a . .
; nonylphenol ethoxylated or triethanol amine salt of an alkylauryl sulfonate or an octylphenoxy polyethoxy ethanol. An amine oxide, a lauryl betaine, or an octylphenoxy polyethoxy ethanol are preferred.
The surfactant can be one or a combination of surfactants - and the total percent by volume ranges from about 0.1 to about 20. The preferred amount of surfactant is about 1 percent by volume.
According to the present invention, the alcohol can be any of a primary, secondary, tertiary, or quaternary alcohol, as long as it is compatible with concentrated chlorinated bleach solutions. The phrase "compatible with chlorinated bleach solutions" means that the alcohol and chlorinated bleach solutions are soluble in each other without reacting or changing their chemical composition.
Specific examples of suitable alcohols that are useful in the present composition, on a lO0 percent basis, include methyl alcohol, ethyl alcohol and its denatured counterparts, and isopropyl alcohol.
Isopropyl alcohol and/or methyl alcohol are preferred.
Ethyl alcohol and its denatured counterparts are less desirable because of high cost and the complexity of the denaturant formulas. Higher alcohols such as butyl, octyl, and decyl alcohol are not desirable because they dry too slowly.
The alcohol aids the penetration of the surfactant and bleach (hypochlorite) into the surface and helps emulsify . ,i ~
undesirable oils.
The alcohols can be used alone or in combination.
The alcohol is used in an amount of from about 0.1 to about 8 percent by volume, and an amount of about 0.5 to 1.0 percent by volume is preferred.
~-; According to the present invention, the chlorinated bleach solution can be any of sodium hydrochlorite, potassium hypochlorite or calcium hypochlorite. Calcium hypochlorite is less preferred because the calcium ion is relatively insoluble and causes surfactants, soaps or detergents to become inactive.
In the present composition, the hypochlorite removes mold, mildew, fungus and algae usually associated with dampness and moisture. The reducing action of the chlorine in the hypochlorite solution whitens and brightens the surface returning it to its original state as when new.
The bleach solution is used in an amount of from about 0.025 to about 0.35 percent by volume of a 100 percent chlorinated . .
` bleach solution, and about 5 percent by volume is preferred.
Further, in practice, the stock solution is a 5 percent solution.
Therefore, 0.025 percent by volume of a 100 percent chlorinated bleach solution would actually involve using 0.5 percent by volume of a 5 percent stock solution.
The balance of the composition is water or water and other additives which do not affect the efficacy of the composition.
The water can be tap water, deionized water or distilled water.
Examples of other ingredients that can be used in the ..
composition include perfumes, odorants and/or masking agents for the odors of the hypochlorites and colorants. In addition certain silicones such as those used in the car wash industry commonly called amino-functional may be added to leave the wood water proofed for a short period of time after cleaning. The silicone must be compatible with the oil or solvent based final water proofing applied after using the composition of the present ; invention. Suitable perfumes, odorants and/or masking agents as well as suitable silicones can be readily selected by those skilled in the art of manufacturing silicones and their ; emulsions. Examples of suitable silicones include the aminofunctional type such as those sold under the trade names "DOW 531" and "DOW 536" and aminofunctional silicones which are offsets to the DOW materials such as those manufactured by General Electric, Waccker Silicones, P.P.G. and others, both foreign and domestic.
:' ~ .
;, ,.
The silicone additives are used in an amount of from 1 to 5 percent by volume of the final ~omposition, which will be an emulslon .
Suitable amounts of the other additives can be readily determined by those skilled in the art.
The composition according to the present invention can be used to clean a broad range of surfaces. The composition is unusual in that it can be used on such a wide range of materials.
i Any kind of wood (pine, cedar, redwood, mahogany, salt treated, juniper, cypress, etc.) can be treated, with the exception of teak. Other surfaces which can be cleaned with the inventive composition include vinyl, fiberglass, ceramic tile, concrete, brick, canvas, stone, roof shingles made of asphalt, wood, tile, or fiberglass, plastics, and aluminum. The composition has been used on houses, decks, boats, trailers, roofs, driveways, walkways, stonewalls, fences, and lawn furniture. In all cases, - the same ultra-fast amazing results were obtained.
The most appealing aspect of the inventive composition to the consumer is that it can be applied by virtually any method, including brushing, pouring, brooming, or spraying, including high pressure or low pressure as obtained, for example, from a garden hose. The most efficient method of application is spraying. The composition is then let to stand for 15 minutes and washed off with water, usually by spraying the water from a ~5 garden hose.
The coverage of the inventive composition ranges from about 200 square feet to about 300 square feet per gallon. The difference depends upon the type and condition (e.g. dryness) of :` 9 the surface. Thus a smooth hard surface, such as fiberglass, will require less than an old dried out wood surface. The ` necessary coverage can readily be determined by first testing a small area of the surface to be cleaned.
The newly cleaned wood will last for many months and if unprotected will simply age as it did before. Other surfaces ; such as ceramic tile, concrete, brick, fiberglass, stone, and , ~
canvass will collect dirt and stains as they did before and over a period of months will require recleaning.
The present invention will now be described by means of examples, which are not meant to be limiting. Unless otherwise v specified, all percents, parts, and rat:ios are by volume.
ln all of the examples, the cleaning composition had the lS following composition (all percents are by volume):
(A) 1 percent lauryl betaine, (B) 0.5 percent isopropyl alcohol, (C) 5 percent sodium hypochlorite, and (D) remainder water.
Further, all of the tests were followed over an eight-month period and absolutely no damage or detrimental effects to the cleaned materials or their surroundings were found.
A blackened portion of a house with two different styles of wood siding, horizontal lap siding above and split shakes below, was treated as described below. Both materials were fashioned from white cedar wood. The treated area included i ~ .
. ~
~' .
.
. .
an "ANDERSON" window with a vinyl clad exterior. A well-kept flower garden was located immediately below the test area.
(1) A standard low pressure garden pump-up type sprayer ` was used to apply the composition to the surfaces while dry.
(2) The initial cleaning action was very dramatic and visually lightened and cleaned the wood in approximately ten seconds. But upon close inspection some of the mold, mildew, algae, and dirt stain areas were found to be slightly lighter and cleaner than others. The composition was allowed to soak in for - fifteen minutes, and the entire area blended into one clean surface at that point.
