The present invention relates to a spraying device suitable for spraying cleaning compositions and rinse water onto hard surfaces. More particularly the spraying device may be attached to a hose, for example a conventional garden hose, so that the cleaning composition and rinse water can be applied to outside surfaces, such as vehicles or the outside surface of windows. The spraying device comprises a purifier located inside the cavity of a container and a spray head.

1. A hand-held spraying device comprising one or more containers, a water purifier, and a spray head, all of which are part of said device during use of said device, wherein the one or more containers contains a cleaning composition that is distinct from a supply of water, but which may be mixed with a supply of water, and the spray head comprises an integrated valve system designed to facilitate compliance with a three or more separate step wash and rinse process, wherein one of said steps comprises a step of spraying the cleaning composition in the one or more containers which has been mixed with said supply of water, wherein the spray head comprises a means for connection to a hose which defines a water inlet, attachment means for attachment of the spray head to the one or more containers, said attachment means comprising an interlocking surface which is designed to cooperate with a corresponding interlocking surface of the one or more containers, a means for removal of a composition from one or more containers, and said valve system is suitable for controlling water flow through the spray device and at least one spray nozzle wherein the interlocking corresponding surfaces of the spray head and the one or more containers are so designed as to align an opening of the one or more containers and the opening of the purifier with corresponding holes in the spray head.2. A hand-held spraying device comprising one or more containers, a water purifier, and a spray head, all of which are part of said device during use of said device, wherein the one or more containers contains a cleaning composition that is distinct from a supply of water, but which may be mixed with a supply of water, and the spray head comprises an integrated valve system designed to facilitate compliance with a three or more separate step wash and rinse process, wherein one of said steps comprises a step of spaying the cleaning composition in the one or more containers which has been mixed with said supply of water, another step comprises an unpurified water rinsing step, and one step comprises a purified water rinsing step, wherein the spray head comprises a means for connection to a hose which defines a water inlet, means for removal of a composition from one or more containers, and said valve system is suitable for controlling water flew through the spray device and at least one spray nozzle wherein the means for removal of a composition from the one or more containers comprises a tube which is attached to the spray head and extends into the cavity of the the one or more containers.3. A hand-held spraying device comprising one or more containers, a water purifier, and a spray head, all of which are part of said device during use of said device, wherein at least one of the one or more containers contains a cleaning composition that is distinct from a supply of water, but which may be mixed with a supply of water, and the spray head comprises an integrated valve system designed to facilitate compliance with a three or more separate step wash and rinse process, wherein one of said steps comprises a step of spraying the cleaning composition in the at least one container which has been mixed with said supply of water, wherein the spray head comprises a means for connection to a hose which defines a water inlet, attachment means for attachment of the spray head to the one or more containers, a means for removal of a composition from one or more containers, and said valve system is suitable for controlling water flow through the spray device and at least one spray nozzle, wherein the valve system comprises at least three channels comprising:(a) a first channel aligning the water inlet and the means for removal of a composition from the at least one container; (b) a second channel aligning the water inlet and the spray nozzle; and (c) a third channel aligning the water inlet and the purifier. 4. A process of cleaning a surface using the spraying device according to claim 3 comprising the steps:(a) rotating the valve to align the first channel, permitting inlet water to pass through the valve, across the opening of the means for removal of the composition to a first spray nozzle; then (b) rotating the valve to align the second channel, permitting inlet water to pass through the valve to a second spray nozzle; then (c) rotating the valve to align the third channel, permitting inlet water to pass through the valve, then through the purifier to the third spray nozzle. 5. A process according to claim 4 wherein step (b) is performed both before and after step (a).6. A process according to claim 4 wherein the spraying device presents a visual indication when step (c) is effected.7. A process according to claim 6 wherein the visual indication is a difference in spray pattern between step (b) and step (c).8. A hand-held spraying device comprising a container, a water purifier, and a spray head, all of which are part of said device during use of said device, wherein the container contains a cleaning composition that is distinct from a supply of water, but which may be mixed with a supply of water, said composition comprising a component capable of rendering the surface treated therewith hydrophilic, and the spray head comprises an integrated valve system designed to facilitate compliance with a three or more separate step wash and rinse process, wherein one of said steps comprises a step of spraying the cleaning composition in the container which has been mixed with said supply of water, another step comprises an unpurified water rinsing step, and one step comprises a purified water rinsing step, wherein the component capable of rendering the surface treated therewith hydrophilic is selected from the group consisting of a homo- or co-polymer.9. A spraying device according to claim 8 wherein the hydrophilic surface modifying component comprises at least one hydrophobic or cationic moiety and at least one hydrophilic moiety.
