The hard surfaces to be cleansed and/or degreased may be plastic, glass, ceramic, porcelain and stainless steel. The equipment to be cleansed and/or degreased may be food service equipment such as ovens, ranges, fryers, grills, steam cookers, refrigerators, coolers, holding cabinets, cold food tables, work tables, beverage dispensing equipment, beer dispensers, shelving, food displays, dish washing equipment and grease traps. ## Claims ### Claim 1 A system, comprising: a housing with openings for a water inlet and a water outlet; an ozone generator disposed within the housing; a venturi disposed within the housing, in between the water inlet and the water outlet, the venturi being coupled to the ozone generator and configured to introduce ozone generated by the ozone generator into water received from a water source via the water inlet; an indicator on an exterior of the housing, wherein the indicator is a light source; a power source configured to provide power to the ozone generator; a flow meter in between the water inlet and the water outlet; an oxidation reduction potential (ORP) meter; and a relay coupled to the indicator, the power source, the flow meter, and the ORP meter, the relay configured to provide an activation signal to the indicator in response to receiving all three of: (1) a first signal from the power source indicating that the power source is providing power to the ozone generator; (2) a second signal from the flow meter indicating that fluid is flowing from the water inlet to the water outlet; and (3) a third signal from the ORP meter indicating that an ORP of at least 600 mV is detected in the water being output by the system. ### Claim 2 (depends on 1) The system of claim 1, wherein the venturi is arranged horizontally along a bottom of the housing. ### Claim 3 (depends on 1) The system of claim 1, wherein the opening for the water inlet is on a first side of the housing, and the opening for the water outlet is on a second side of the housing that is opposite the first side of the housing. ### Claim 4 (depends on 1) The system of claim 1, further comprising a removable cover configured to enclose one or more ozone generators and one or more venturis within the housing when the removable cover is secured. ### Claim 5 (depends on 1) The system of claim 1, wherein the housing further includes an opening for a power source connection. ### Claim 6 (depends on 1) The system of claim 1, further comprising a switch on an exterior of the housing, the switch being coupled to the power source from within the housing and configured to engage or disengage power to the ozone generator and the other components inside the housing. ### Claim 7 (depends on 1) The system of claim 1, further comprising an air dryer disposed within the housing, the air dryer being configured to remove moisture from air before the air enters the ozone generator. ### Claim 8 A portable device, comprising: a housing that includes: a water inlet a water outlet; an ozone generator; a venturi in between the water inlet and the water outlet, the venturi being coupled to the ozone generator and configured to introduce ozone generated by the ozone generator into water received from a water source via the water inlet; an indicator on an exterior of the housing, wherein the indicator is a light source; a power source configured to provide power to the ozone generator; a flow meter in between the water inlet and the water outlet; an oxidation reduction potential (ORP) meter; and a relay coupled to the indicator, the power source, the flow meter, and the ORP meter, the relay configured to provide an activation signal to the indicator in response to receiving all three of: (1) a first signal from the power source indicating that the power source is providing power to the ozone generator; (2) a second signal from the flow meter indicating that fluid is flowing from the water inlet to the water outlet; and (3) a third signal from the ORP meter indicating that an ORP of at least 600 mV is detected in the water being output by the system. ### Claim 9 (depends on 8) The portable device of claim 8, wherein the venturi is arranged horizontally along a bottom of the housing. ### Claim 10 (depends on 8) The portable device of claim 8, wherein the water inlet is located at a first side of the housing, and the water outlet is located at a second side of the housing that is opposite the first side of the housing. ### Claim 11 (depends on 8) The portable device of claim 8, wherein the housing further includes a removable cover configured to enclose one or more ozone generators and one or more venturis within the housing when the removable cover is secured. ### Claim 12 (depends on 8) The portable device of claim 8, wherein the housing further includes a power source connection. ### Claim 13 (depends on 8) The portable device of claim 8, wherein the housing further includes a switch on an exterior of the housing, the switch being coupled to the power source connection from within the housing and configured to engage or disengage power to the ozone generator and the other components inside the housing. ### Claim 14 (depends on 8) The portable device of claim 8, wherein the housing further includes an air dryer configured to remove moisture from air before the air enters the ozone generator.
