     TECHNICAL FIELD 
     The present invention relates to cleaning apparatuses. Specifically, the present invention comprises an attachment for a standard shower head, faucet, spigot, or other water line implement, wherein the attachment comprises a valve for routing water through a tube into a sprayer having an amount of cleaner therein, wherein the water and cleaner mix to form a cleaning solution that sprays from the sprayer as a foam. The sprayer reduces the velocity of the cleaner mix by a combination of a fluid spreader and one or more screens, allowing the cleaning mix to spray onto a surface for cleaning the same. Preferred detergent compositions are further provided. Exemplary items to be cleaned including bathroom surfaces, windows, car engines, AC coils, cooling tower louvres, and other delicate surfaces requiring reduced water velocity and increased clinging of the cleaning foam mix. 
     BACKGROUND 
     It is, of course, desirable to clean surfaces to remove germs, dirt, grease or other like contaminants. However, certain surfaces are oftentimes difficult to clean due to the extent of contaminants and/or pathogens. For example, bathtubs and showers routinely require cleaning. Bathtubs and showers are utilized primarily for cleaning humans or animals, and as such dirt, viruses and/or bacteria may remain after use. Moreover, the moisture and heat generated by a bathtub or shower can lead to organic growth, such as mold and mildew. There are many products on the market for cleaning these areas, including powders, concentrates, mixes, sprays, or other like cleaners that can be deposited onto a surface within a bathtub or shower enclosure for cleaning the same. 
     In addition, it is often desirable to clean surfaces of objects that may be delicate, that may be damaged by a high pressure spray of cleaning mixture. For example, certain object such as engines, motors, AC equipment, cooling tower louvres, to name a few, may require cleaning to operate at peak efficiency, but spraying the same with high pressure water or cleaner may cause damage to the object. 
     Oftentimes, cleaners are difficult to work with when cleaning surfaces of the aforementioned bathrooms, showers, or delicate objects. If a powder, concentrate or mixture, they must often be mixed with water, typically within a bucket or other like container. Combining requisite ingredients together can be messy, time consuming, and may be done improperly, causing the cleaners to lose their effectiveness. 
     Moreover, cleaners in pressurized sprayers, such as spray cans and the like, are often limited based on their size, and typically when emptied, are thrown away as they are typically not refillable. This can lead to much waste, especially if cans or spray bottles have caustic cleaning residue therein, which can pose additional environmental challenges for waste disposal thereof. 
     Moreover, typical cleaners often are difficult to apply, and often fail to provide adequate coverage or foaming properties to maximize the contact of cleaning ingredients on surfaces. Specifically, cleaners that are powders, concentrates, or mixes typically have little to no foaming properties. Moreover, cleaners that are sprayed from spray cans often only superficially cover surfaces without providing sufficient contact to surfaces. Oftentimes, chemical cleaners are either activated or provide enhanced cleaning power when used at elevated temperatures. However, typical foaming cleaners expelled from pressurized cans or the like are dangerous if heated and so cannot take advantage of enhanced cleaning due to added heat. Another drawback of typical spray cleaners is oftentimes the expulsion of foaming cleaning solution is difficult to control, and can results in splash back of the chemicals onto a user&#39;s body. 
     As noted above, water is often required to be mixed with powders, concentrates, mixes or the like for proper cleaning capabilities. When cleaning a bathtub or shower enclosure, it is often difficult to utilize the faucets to fill buckets or other like containers with water and mix with cleaning solution. 
     A need, therefore, exists for improved cleaning apparatuses for surfaces. More specifically, a need exists for cleaning apparatuses that provide adequate cleaning capability to surfaces. 
     Moreover, a need exists for cleaning apparatuses that provide sufficient coverage of cleaning solutions to surfaces. In addition, a need exists for cleaning apparatuses that provide sufficient foaming of cleaning solutions to maximize cleaning of the surfaces. 
     In addition, a need exists for cleaning apparatuses that may provide enhanced cleaning power due to use at elevated temperatures. Moreover, a need exists for cleaning apparatuses that offer easy control of foaming so that chemical splash-back is minimized or eliminated. 
     Further, a need exists for cleaning apparatuses that allow for proper mixing of water and cleaning solution, and further provide an easy and efficient foaming capability. Still further, a need exists for detergent compositions useful for improved cleaning apparatuses.

     DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS 
     The present invention relates to cleaning apparatuses. Specifically, the present invention comprises an attachment for a standard shower head, faucet, spigot, or other water line implement, wherein the attachment comprises a valve for routing water through a tube into a sprayer having an amount of cleaner therein, wherein the water and cleaner mix to form a cleaning solution that sprays from the sprayer as a foam. The sprayer reduces the velocity of the cleaner mix by a combination of a fluid spreader and one or more screens, allowing the cleaning mix to spray onto a surface for cleaning the same. Preferred detergent compositions are further provided. Exemplary items to be cleaned including bathroom surfaces, windows, car engines, AC coils, cooling tower louvres, and other delicate surfaces requiring reduced water velocity and increased clinging of the cleaning foam mix. 
       FIG. 1  illustrates a cleaning apparatus  10  in an embodiment of the present invention. The cleaning apparatus  10  may be utilized to clean a surface or an object, and the present invention should not be limited as described herein. In a preferred embodiment, the cleaning apparatus  10  may be utilized for cleaning the surfaces of a bathroom, such as the interior surfaces of a shower, bathtub, shower stall, hot tub, or other like surfaces within a bathroom. In other embodiments, the cleaning apparatus  10  may be utilized for cleaning delicate objects that require reduced velocity pressure of water and/or water and detergent mixtures. 
     The cleaning apparatus  10  may be connected to a water dispensing pipe via connector  12 . The connector  12  may be connected to a shower dispensing pipe, for example, or any other pipe that allows water to be dispensed therefrom. The connector  12  comprises an inlet  14 , an outlet  16 , and a cleaning apparatus outlet  18 . The connector  12  may further comprise a valve  20  for changing the flow of water through the connector, such as between flowing from the inlet  14  to the outlet  16  and flowing from the inlet  14  to the cleaning apparatus outlet  18 . The connector  12  may be placed in-line with a shower head or other like water dispensing pipe, and may further be utilized with a hot and cold water valve for adjusting the temperature thereof. 
     Preferably, the connector  12  may be connected in-line with a shower head inlet, allowing a user to switch between dispensing the water through the shower head and dispensing the water through the cleaning apparatus  10 . Thus, the cleaning apparatus  10  may be utilized within a shower or bathtub enclosure to clean the surfaces thereof easily and efficiently. The connector  12 , in a preferred embodiment, may be connected permanently in-line with the shower head, and tubing  22  may extend from the connector  12 . The tubing  22  may preferably be pressure fit onto a tube fitting (not shown) at the cleaning apparatus outlet  18 , and therefore may be held onto the connector  12  when in use and removed therefrom when not in use. Therefore, a user may attach the tubing  22  to the pressure fitting on the cleaning apparatus outlet  18  of the connector  12  when use is desired. 
     The tubing  22  may preferably comprise a flexible tube that may route water from the connector  12  to a sprayer apparatus  30 . The sprayer apparatus  30  may preferably route cleaning solution from a container  32  having an amount of detergent therein, where the detergent may have been previously combined with the water and form a cleaning solution. The cleaning solution may then be extracted from the container  32  as water flows through the sprayer apparatus  30  via the Venturi Effect and ejected from the sprayer apparatus  30  to cover a surface for cleaning the same. 
     As illustrated in  FIG. 2 , the sprayer apparatus  30  may comprise several components. Specifically, the sprayer apparatus  30  may comprise a spray module  34  that may accepts water from the tubing  22 , such as through a spray module inlet  36  comprising a tube fitting (not shown) thereon. The spray module  34  may further comprise a trigger  37  acting as a valve that may alternately allow and prevent water from flowing through a nozzle  38 . The water may thereby flow from the nozzle  38  through a chamber  40  to flow directly out a cleaning apparatus outlet  42 . If the container  32  comprising the cleaning solution is open, the water flowing through the chamber  40  may pull the cleaning solution from the container  32  via the afore-mentioned Venturi Effect. Alternately, if the container  32  is closed and cleaning solution cannot flow into the chamber  40 , water may flow directly therethrough to be used as a rinse. 
     Specifically, the chamber  40  may comprise 3 settings: 1) a “clean” setting that may route cleaning solution from the container  32  for mixing with water flowing therethrough; 2) a “rinse” setting that may close off the container  32  and route the water directly through the cleaning apparatus outlet  42 ; and 3) an “off” setting that blocks water from either entering the container  32  and bypassing the container  32 . The setting may be in the form of a dial that allows a user to set the route of water through the chamber  40 . 
     When the “clean” setting is selected, water from the spray module  34  may be routed through the chamber  40  and may pull cleaning solution from the container  32  due to passage from the container  32  of cleaning solution from the container  32  into the chamber  40  via a spray tube  44 . As the cleaning solution is pulled up the spray tube  44  and mixes with the water, the cleaning solution and water mixture may be routed through the cleaning apparatus outlet  42 . Thus, cleaning solution and water mixture may thus be applied to a surface or object for cleaning thereof. Likewise, when the “rinse” setting is selected, the container  32  may be closed and the water routed directly through the cleaning apparatus outlet  42  to be used for spraying pure water without cleaning solution therein to rinse a surface or an object. The water may flow through the various components when the trigger  37  is squeezed by a user, allowing pressurized water to flow therethrough, depending on the setting. 
     It should be noted that the water flowing through various components may experience pressure increases and drops as it flow therethrough, due to passage through relatively constricted and unrestricted passages. The overall effect may be a pressure drop of the water flowing therethrough that allows the cleaning solution and water mixture and/or the water by itself to be sprayed onto a surface or an object while minimizing splash-back. Minimizing splash-back may be particularly useful when spraying the cleaning solution and water mixture, as it minimizes contact between the cleaning solution and a user thereof. 
     As illustrated in  FIG. 2 , the container  32  may be separable from the chamber  40  through a screw cap. Likewise, the spray module  34  may be separable from the chamber  40  also through a screw cap. The cleaning apparatus outlet  42  may further be separably connected to the chamber  40 , such as via threads, but may also be pressure fit to the chamber. The cleaning apparatus outlet  42  may allow the both the cleaning solution and the rinse water to eject therefrom, forming a spray of either to maximize coverage. 
     In a preferred embodiment, illustrated in  FIG. 3 , a cross-sectional view of the cleaning apparatus outlet  42  is illustrated. A cleaning solution and water mixture or rinse water may flow through a main housing  50 . The main housing  50  may have a screen  52  on an end thereof that the water and cleaning solution must pass through. The screen  52  may preferably be held to the end thereof via a cap  54  that may be held onto the end thereof in any manner apparent to one of ordinary skill in the art, such as via threads, pressure fit, adhesive, or in any other like manner. The screen  52  may agitate and break up the water stream and the cleaning solution stream and form a spray. More preferably, the screen  52  may break up and agitate the cleaning solution stream, enhancing the formation of cleaning suds or foam that may be utilized on a surface or an object to maximize cleaning thereof. In a preferred embodiment, the screen  52  may preferably be formed from several screens that are placed adjacent one another, thereby providing a tortuous path for the cleaning solution to flow through, thereby even further enhancing the agitation and the creation of suds and foam. The screen  52  may also contribute to minimizing splash-back of the cleaning solution and water mixture by interfering with and therefore decreasing the flow rate of the mixture therethrough. 
     All of the various components may be modular and separable from each other, as shown in  FIG. 2 , to allow the parts to be easily taken apart for cleaning and/or storage thereof. As noted above, the various parts may be connected to each other through separable connections, such as through pressure fittings and/or through threaded connections as apparent to one of ordinary skill in the art. Thus, a single cleaning apparatus  10  may be utilized to clean several bathtub or shower enclosures, such as may be found within a hotel, motel dormitory or other like facility having multiple shower or bathtub enclosures. Of course, the present invention may also be useful within a home having a plurality of bathrooms therein for the same purpose. Thus, the cleaning apparatus  10  may be brought to each bathroom for cleaning the same, whereby the tubing  22  is hooked up to a connector  12  that may be permanently disposed in each bathroom, pressure fit to the cleaning apparatus outlet  18  thereof, and utilized as disclosed above for cleaning the surfaces thereof. 
     The detergent that may be utilized within the container  32  and mixed with the water may be any detergent useful for serving such a purpose, and may further easily dissolve in water and create suds for cleaning and/or sterilizing surfaces or objects. In a preferred embodiment, the detergent may be contained within a water soluble pouch that may dissolve when introduced to water. Within the soluble pouch may be a dry or liquid detergent concentrate that, when dissolved within the water introduced to the container  32 , forms an effective cleaning solution for use with the present invention. 
     Specifically, the container  32  may preferably have two openings, a first opening for disposing on the spray apparatus  30 , wherein the spray tube  44  may pull cleaning solution into the chamber  40 , and a second opening (shown at the bottom of the container  32 ) whereby both the detergent and sufficient water to dissolve the same to form the cleaning solution may be introduced. Preferably, the detergent, within a water soluble pouch, may be disposed within the container  32  through the second opening followed by an amount of water. Alternatively, water may first be disposed within the container  32  through the second opening followed by introduction thereto of the detergent within the water soluble pouch. The container  32  may be closed and the detergent may be dissolved within the water. 
     Although any detergent composition may be utilized, as apparent to one of ordinary skill in the art, a preferred detergent composition easily produces bubbles and foam to aid in cleaning a surface or an object, causing the cleaning solution to better cling to the surface or object. As noted above, the screen  52  may mechanical stress the cleaning solution, agitating the cleaning solution to produce foam. Likewise, a detergent composition that produces foam upon contact with water is preferred. For example, a CO2-producing detergent composition may create foam when in contact with water. When the CO2-producing detergent composition is further agitated through the screen  52 , foaming of the cleaning solution may be enhanced. In the event of using a CO2-producing detergent that may be activated with heated water, the detergent may be dissolved in cold water within the container  32  to minimize pressure build-up and to prevent or delay the release of CO2. Then, when the cold cleaning solution within the container  32  is pulled into the chamber  40 , the water flowing therethrough may be heated water, causing the cold cleaning solution to mix with the heated water and activating it, producing enhanced cleaning abilities, such as formation of CO2 and foam thereby. 
     The following provides various detergent compositions that may be useful for cleaning surfaces and/or objects according to the present invention:

     CO2 may be produced according to Formula #2 due to the presence of sodium bicarbonate and an acid, such as citric acid, in contact with water. Other acids may further be useful, such as malic acid, succinic acid, adipic acid, or any other acid apparent to one of ordinary skill in the art to react with the sodium bicarbonate in the presence of water to form a carbonated cleaning solution. Specifically, CO2 may be produced when Formula #2 is dissolved in water, such as when water is added to the container  32  and dissolves a water soluble pouch containing Formula #2. For example, a 56 g water soluble pouch of Formula #2 dissolved in 1 L of water produces around 4.4 g of CO2, thereby producing a carbonated cleaning solution. When in contact with hot water, CO2 solubility may decrease, forcing the CO2 gas to leave the liquid phase. When CO2 leaves the liquid phase, foam may be produced when the CO2 forms bubbles with the surfactant, such as an alkyl benzene sulfonic acid, namely dodecyl benzene sulfonic acid, Na salt (commonly known as Thonyl or DDBSA), as shown in Formulas #1 and #2. Moreover, as noted above, the mechanical stress of the cleaning solution hitting the foam screen and agitated thereby favors bubble release from the liquid which, in conjunction with the surfactant, may produce high foam.
