Abstract
A spray dispenser comprises a housing and a nozzle. The housing contains a reservoir for storing liquid, an electrolytic cell for receiving liquid from the reservoir and increasing the level of oxidative properties in the liquid, and a pump for circulating fluid between the reservoir and the electrolytic cell so that liquid having enhanced oxidative properties in dispensed from the nozzle. In the preferred embodiment, the electrolytic cell generates hydrogen peroxide from water introduced to the reservoir by the user so that a sterilising solution of hydrogen peroxide is dispensed from the nozzle.
