- (a) 2 to 10% of water-soluble hypochlorite,
- (b) 0.025 to 0.5% of at least one fluorescent whitening agent, wherein the fluorescent whitening agent is a bis(benzofuranyl) compound of formula I ##STR4## wherein n is 2 to 4, M is hydrogen or an equivalent of a non-chromophoric cation, and wherein the compound of formula I is unsubstituted or substituted by one or more substituents selected from the group consisting of halogen, C.sub.1 -C.sub.4 alkyl and C.sub.1 -C.sub.4 alkoxy, the fluorescent whitening agent being present in the bleach solution in the absence of additional stabilizing means, and
