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)

Claims

1. A method of cleaning an object, comprising providing a hand-held spraying device:

directing a first stream of high pressure water from the hand-held spraying device toward the object; and

directing a second stream of ozone/water from the hand-held spraying device toward the object;

wherein

the steps of directing the first stream of high pressure water and directing the second stream of ozone/water are accomplished simultaneously.

2. The method of claim 1, wherein the first stream of high pressure water and the second stream of ozone/water are substantially parallel to one another.

3. The method of claim 1, wherein the first stream of high pressure water is adjacent to the second stream of ozone/water without admixing the ozone to the stream of high pressure water for a substantial distance.
