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 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 5-chloro-2-(2,4- dichlorophenoxy)phenol, trichlorcarbanilide, hexachlorophene, chlorhexadine, o- phenylphenol, benzylquaternium salts and mixtures thereof.

La présente invention concerne un procédé de nettoyage d'un article textile contaminé par un ou plusieurs agents microbiens. Le procédé consiste a) à placer l'article textile dans un sac non étanche aux vapeurs et contenant déjà une composition nettoyante comprenant de l'eau, et b) à soumettre le sac non étanche aux vapeurs à une source de chaleur qui fournit suffisamment de chaleur pour vaporiser l'eau, ce qui expose les agents microbiens aux vapeurs d'eau ainsi obtenues. Cette opération permet de tuer au moins environ 50% des agents microbiens. La compositions nettoyante comprend de préférence au moins un agent antimicrobien appartenant au groupe des 5-chloro-2-(2,4-dichlorophénoxy)phénol, trichlorocarbanalure, peroxyde d'hydrogène, autres blanchissants oxygénés, 4-chloro-3,5-diméthylphénol, iode et/ou iodophores, chlorhexidine, phénols, phospholipides, thymol, eugéniol, géraniol, huile de citronelle, limonène et certains de leurs mélanges. Le procédé de l'invention comporte en outre de préférence le prétraitement d'au moins une partie du tissu avec une composition de prétraitement comprenant un agent antomicrobien appartenant au groupe des 5-chloro-2-(2,4-dichlorophénoxy)phénol, trichloro-diphénylcarbamide, hexachlorophène, chlorhexadine, o-phénylphenol, des sels de benzyl quaternaire et certains de leurs mélanges.
