Abstract:
A fluid cycling cleaning system, including:a reservoir, and an aqueous surface cleaning composition contained in the reservoir, said cleaning composition consisting essentially of water, and from about 10 ppm to about 200 ppm by weight of a surfactant component resistant to interacting with ozone and selected from the group consisting essentially of: low foaming anionic surfactants; and ethylene oxide, propylene oxide block copolymers having HLB values of at most 7:a fluid dispensing conduit in fluid communication with the reservoir for conveying the cleaning composition from within the reservoir to an application area outside of the reservoir, and a fluid recovery conduit for recovering the cleaning composition from the application area; wherein the reservoir, the fluid dispensing conduit and the fluid recovery conduit cooperate to provide a fluid pathway for the cleaning composition;an ozone source, fluid coupled to the fluid pathway, for introducing ozone into the cleaning composition, whereby at least some of the ozone is dissolved into the cleaning composition; andan applicator fluid-coupled to the dispensing conduit for applying the cleaning composition, with ozone dissolved therein, to the application area.
