1. A method of cleaning and sanitizing an object, comprising;
- forming a wash water into a high pressure first stream and directing it onto the object to be cleaned;
forming ozonated water into a second stream and discharging it closely adjacent and simultaneous with the first stream of high pressure wash water but without admixing the ozone to the high pressure wash water stream for a substantial distance;
regulating the pressure of the high pressure wash water stream to exert a cleaning force on the object to be cleaned; and
directing the high pressure wash water stream onto the object to be cleaned; and
directing the ozonated water stream onto the object after it has been cleaned by the high pressure wash water stream, and using the ozonated water stream to sanitize the same object.

Abstract
A high pressure water stream (14) is discharged onto a surface to be cleaned. An ozone/water stream (16) is discharged on the same surface for sanitizing the surface. The high pressure water and ozone/water streams (14, 16) are discharged simultaneously along closely adjacent paths that are either parallel (FIG. 3) or concentric (FIG. 2). The water pressure is at least about 100 p.s.i. and is preferably between 100 p.s.i. and 1000 p.s.i. The nozzles that discharge the streams (14, 16) may be movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1) Or, they may be fixed and the object may be movable relative to them (FIG. 4).

10. A method of cleaning and sanitizing an object, comprising;
-
forming a wash water into a high pressure first stream and directing it onto the object to be cleaned; forming ozonated water into a second stream and discharging the ozonated water stream as an annular stream that concentrically surrounds the high pressure wash water stream without admixing the ozone to the high pressure wash water stream; regulating the pressure of the high pressure wash water stream to exert a cleaning force on the object to be cleaned; and directing the high pressure wash water stream onto the object to be cleaned; and directing the ozonated water stream onto the object after it has been cleaned by the high pressure wash water stream, and using the ozonated water stream to sanitize the same object.
