Claim:
A bathing system for projecting a mixture of water and at least one injectant onto an object for washing the object, the system comprising: (a) a first injectant dispenser for storing an injectant; (b) a water sprayer having an inlet and outlet; and (c) an injector having a primary inlet in fluid communication to a water source, an outlet in fluid communication to the inlet of the water sprayer, and an injectant inlet in fluid communication with the first injectant dispenser, whereby the injectant can be introduced into the water flowing through the injector, the water sprayer and injector maintaining a water-to-injectant ratio to within a range of about a 50% variation of a midpoint of a mixing ratio range associated with the injectant when water flow rate is no higher than about 4.0 gallons per minute and varies over a range of 20% of a midpoint of a range associated with the water flow rate.
