What is claimed is: 1. A portable water purifying device in combination with a spray device, said spray device removably attached to an end of a hose which is attached to a supply of tap water, said portable water purifying device positioned in said spray device and comprising: a portable purifier
What is claimed is: 1. A portable water purifying device in combination with a spray device, said spray device removably attached to an end of a hose which is attached to a supply of tap water, said portable water purifying device positioned in said spray device and comprising: a portable purifier cartridge comprising a sequential arrangement of at least a first bed of a SAC ion exchange resin having a length from 5 inches to 7 inches followed by a second bed of a WBA ion exchange resin having a length from 4 inches to 6 inches, and, optionally, followed by one or more additional beds of ion exchange resins selected from the group consisting of SAC ion exchange resins, WBA ion exchange resins, SBA ion exchange resins, WAC ion exchange resins, and mixtures thereof; wherein said portable purifier cartridge comprises ion exchange resin beads that are less than 0.6 mm in diameter; and wherein said tap water flows from said hose into said spray device and into said portable water purifying device and through said portable purifier cartridge at a flow rate of greater than 14 gallons/minute/ft3 of the total volume of ion exchange resin and effluent water having a conductivity of less than or equal to about 50 micromho is provided for spraying from said spray device. 2. The purifying device of claim 1 wherein water flows through said portable purifier cartridge at a flow rate of greater than or equal to about 20 gallons/minute/ft3. 3. The purifying device of claim 1 wherein said portable purifier cartridge has a total volume of ion exchange resin between about 5 in3 and about 25 in3. 4. The purifying device of claim 1 wherein said first bed and said second bed differ in the size of cross-sectional area, aspect ratio, or both. 5. The purifying device of claim 1 wherein the WBA ion exchange resin comprises a crosslinked copolymer of acrylate containing amino groups. 6. The purifying device of claim 1 wherein the WBA ion exchange resin has a capacity greater than or equal to about 1.1 eq./L. 7. A method of washing a surface using the purifying device of claim 1, said method comprising the steps of (a) washing a surface; and (b) rinsing the surface, wherein the surface is rinsed during at least one rinse step, and the sole rinse step, if there is only one rinse step, or the last rinse step, if there is more than one rinse step, comprises a final rinse, wherein the purifying device is used to rinse the surface with purified water in the final rinse of the process of washing a surface. 8. A method of treating a surface with a surface modifying substance using the purifying device of claim 1, said method comprising the steps of (a) treating a surface with a surface modifying substance that reduces the contact angle of water with the surface to less than about 50 degrees; and (b) (1) rinsing said surface treated with said surface modifying substance with purified water using said purifying device, or (2) rinsing said surface with purified water using said purifying device prior to treating said surface with said surface modifying substance. 9. The purifying device of claim 1 wherein water flows through said portable purifier cartridge at a flow rate of greater than or equal to about 27 gallons/minute/ft3. 10. The purifying device of claim 1 wherein at least some of the ion exchange resin is in the form of beads of less than 0.4 mm in diameter. 11. The purifying device of claim 1 wherein at least one of said resin types comprises a visual indicator to determine depletion of resin exchange capacity. 12. The method of washing a surface of claim 7 wherein the surface is at least a portion of the exterior surface of a vehicle. 13. A portable purifying device for use in an end of the hose water purifier, said purifying device positioned in water purifier and comprising a portable article containing ion exchange resin having a total volume and a length where the water flows from the end of a garden hose into the end of the hose water purifier and into the portable article having a sequential arrangement consisting of a first bed of SAC ion exchange resin and second bed of WBA ion exchange resin at a flow rate of greater than 14 gallons/minute/ft3 of the total volume of ion exchange resin, wherein said ion exchange resins comprise resin beads that are less than 0.4 mm in diameter and the WBA ion exchange resin comprises a crosslinked copolymer of acrylate containing amino groups and wherein said first bed has a length from 5 inches to 7 inches and said second bed has a length from 4 inches to 6 inches.
