An apparatus has a tank with an interior for containing water, a nozzle for directing ozonated water out of the spray apparatus, and an electrolytic cell located between the nozzle and the tank. The electrolytic cell is configured to ozonate water as the water flows from the tank to the nozzle. The apparatus also includes a power source for providing electric potential to the electrolytic cell. The tank, nozzle, and electrolytic cell all are part of a single spray bottle or dispenser (e.g., like a soap dispenser).
