A process for sanitizing a fabric article which is contaminated with one or more microbials. The process steps include: (a) placing the fabric article in a vapor venting bag together with a cleaning/refreshing composition comprising water; and (b) subjecting the vapor venting bag to a heat source which supplies sufficient heat to vaporize the water, thereby exposing the microbials to the resulting water vapor. This process results in at least about 50% of the microbials being killed. The cleaning/refreshing composition preferably comprises at least one antimicrobial agent selected from the group consisting of 5-chloro-2-(2,4-dichlorophenoxy)phenol, trichlorocarbanalide, hydrogen peroxide, other oxygen bleaches, 4-chloro-3,5-dimethylphenol, iodine/iodophors, chlorhexidine, phenols, phospholipids, thymol, eugeniol, geraniol, oil of lemon grass, limonene and mixtures thereof. The process of this invention preferably further comprises the step pre-treating at least a portion of the fabric with a pre-treating composition comprising an antimicrobial agent selected from the group consisting of 5-chloro-2-(2,4-dichlorophenoxy)phenol, trichlorocarbanalide, hexachlorophene, chlorhexidine, o-phenylphenol, benzylquaternium salts and mixtures thereof

1. A process for sanitizing a fabric article which is contaminated with one or more microbials, the process comprising the steps of:a) placing the fabric article in a vapor venting bag together with a cleaning/refreshing composition comprising water and at least one antimicrobial agent selected from the group consisting of 5-chloro-2-(2,4-dichlorophenoxy)phenol, trichlorocarbanalide, 4-chloro-3,5-dimethylphenol, iodine/iodophors, chlorhexidine, phenols, phospholipids, thymol, eugeniol, geraniol, oil of lemon grass, limonene and mixtures thereof;b) subjecting the vapor venting bag to a heat source which supplies sufficient heat to vaporize the water, thereby exposing the microbials to the resulting water vapor and the antimicrobial agent; andwhereby at least about 50% of the microbes are killed. 2. A process according to claim 1, wherein the cleaning/refreshing composition comprises a second antimicrobial agent selected from the group consisting of alkyl alkoxy sulfates, linear alkyl benzene sulfonates, aminc oxides, polyhydroxy fatty acid amides, ethoxylated alcohols, diamines, amides, alkyl polyglucosides, betaines, and mixtures thereof. 3. A process according to claim 1, wherein the cleaning/refreshing composition comprises a nonionic surfactant. 4. A process according to claim 1, wherein the cleaning/refreshing composition comprises a perfume. 5. A process according to claim 1, wherein the cleaning/refreshing composition is releasably absorbed in a carrier. 6. A process according to claim 5, wherein the carrier is in sheet form. 7. A process according to claim 6, wherein the carrier comprises a fibrous, hydroentangled web. 8. A process according to claim 1, which additionally comprises the step of subjecting the vapor venting bag to a tumbling action concurrently with the heat source. 9. A process according to claim 8, wherein the heat source and tumbling action are supplied by a hot air clothes dryer. 10. A process according to claim 1, wherein the vapor venting bag has a VVE rating of at least about 40. 11. A process according to claim 10, wherein the vapor venting bag has a VVE rating of at least about 60. 12. A process according to claim 10, wherein the vapor venting bag has a VVE no greater than about 90. 13. A process according to claim 10, wherein the vapor venting bag has a VVE no greater than about 80. 14. A process according to claim 1, further comprising the step of pre-treating at least a portion of the fabric with a pre-treating composition comprising an antimicrobial agent selected from the group consisting of hydrogen peroxide, other oxygen bleaches, 5-chloro-2-(2,4-dichlorophenoxy)phenol, trichlorcarbanilide, hexachlorophene, chlorhexadine, o-phenylphenol, benzylquaternium salts and mixtures thereof. 15. A process according to claim 14, wherein the pre-treating composition comprises from about 0.05% to about 3%, by weight of the antimicrobial agent. 16. A process according to claim 1, wherein the cleaning/refreshing composition comprises from about 0.05% to about 3%, by weight of the antimicrobial agent. 17. A process according to 1 , wherein the microbials are selected from group consisting of germs, bacteria, viruses, parasites, fungi/spores and mixtures thereof. 18. A process according to claim 17, wherein the microbials are a mixture of fungi. 19. A process according to claim 9, wherein the hot air clothes dryer operates at temperature of from about 40° C. to about 250° C. 20. A process according to claim 1, whereby at least about 90% of the microbes are killed.
