First Claim
1. A method of reducing the microbial load on a surface of a permeable material having a color without significantly bleaching the color of the permeable material, said method comprising:
- contacting the surface with a wash liquor thus wetting the surface;
introducing a combination of ozone and gas, said gas selected from the group consisting of air, oxygen, and mixtures thereof into the wash liquor to form an ozonated wash liquor; and

Abstract
The invention includes a method of reducing the microbial population on a textile in a washing machine. The washing machine has an outer shell for containing fluids and an internal assembly for containing textiles. The method includes introducing a wash liquor into the internal assembly, thus contacting the textile with the wash liquor and wetting the textile. The wash liquor is then removed from the internal assembly and the outer shell at a first point. At a second point, a combination of ozone gas, oxygen and/or oxygen enriched air is mixed into the wash liquor being removed from the outer shell to form an ozonated wash liquor. This ozonated wash liquor is re-introduced into the outer shell and internal assembly thus contacting the textile with the ozonated wash liquor for a period of time.
