Abstract: Method of anti-stain redeposition of stains on textiles in natural, synthetic, or artificial fibres or their mixtures, during operations of dry cleaning or de-oiling by means of stabilised perchloroethylene. It is characterised by the fact that to this perchloroethylene is incorporated a sufficient quantity of one or more than one nitrile chosen in the groups of those whose boiling point is less than or equal to 130 C and of those forming with perchloroethylene an azeotrope whose boiling point is lower than 130 C, in order to obtain an anti-greying effect. Application of this method to textile materials, for example in cotton, wool, polyester, polyacrylonitrile or polyamide.
