An apparatus that can be connected to a conventional sprayer bottle that permits the sprayer bottle to generate ozonated water to be used as a cleaning fluid. The apparatus includes an ozonator element coupled at one end of an electrical cable and an electrical connector coupled at the other end of the electrical cable. An aperture is formed in the sidewall of the bottle and the ozonator element, electrical cable and connector are passed through a top opening in the bottle portion. The electrical connector is then releasably secured within the aperture with the ozonator element being submerged in the water contained within the bottle. The dip tube of the spray head is then passed through the top opening and into the water in the bottle and the spray head is secured onto the bottle. Electrical energy is provided through the connector to the ozonator element to ozonate the water in the bottle for predetermined period of time after which the sprayer bottle contains ozonated water for cleaning. After another predetermined period of time, the ozonator element is energized again to ensure ozonated water is always available. A related apparatus can be connected between a feedpipe and a water reservoir for making the reservoir an ozonating water source.
