A process of removing soil and/or stains from fabrics by immersing the fabrics in a peroxygen bleach bath containing as a peroxygen activator, an anhydride of a carboxylic acid with a sulfonic acid selected from the formulae consisting of R.sub.1 --(SO.sub.2 OC(O)--R.sub.2).sub.n and (R.sub.1 --SO.sub.2 OC(O)).sub.n R.sub.2 wherein n is an integer of 1 to 3; each of R.sub.1 and R.sub.2, which may be alike or different, is selected from the class consisting of a 1 to 3 valent hydrocarbon radical derived from an alkane of 1 to 16 carbon atoms, a cycloalkane of 3 to 7 carbon atoms and an arene of 6 to 12 aromatic carbon atoms while taken together R.sub.1 and R.sub.2 can complete an o-phenylene or an o-naphthalene ring, said hydrocarbon radicals optionally bearing 1 to 3 substituents selected from the class consisting of alkoxy of 1 to 16 carbon atoms on the arene, aliphatic carboxamido of 1 to 16 carbon atoms on the arene, alkyl of 1 to 16 carbon atoms on the arene, benzamido on the arene, nitro, chlorine, bromine and fluorine. Also described are dry blend compositions containing the activator and peroxygen.
