An alkyl and/or aryl silyl ether capped polyether surfactant useful in cleaning compositions. The polyether is described in conjunction with automatic dishwashing detergent composition having improved chlorine bleach stability comprising: (a) an active chlorine containing compound selected from the group consisting of chlorinated trisodium phosphate, chlorinated cyanuric acid and alkali metal salts thereof, 2,3-dichloro-5,5-dimethylhydantoin, hypochlorite bleach and mixtures thereof to yield available chlorine in an amount of from about 0.1 percent to 5 percent; (b) about 0.1 percent to 5 percent of a chlorine bleach stable nonionic surfactant having the general formula: Y¢(AlO)n (A2O)m (A3O)p (X)q A4!z wherein Y is the residue of an organic compound having from 1 to 8, preferably 1 to 4, reactive hydrogens as measured by the Zerevitinov determination method; z is a number from 1 to 8, A1, A2 and A3 are C2 to C4 alkylene groups, tetramethylene, and mixtures thereof; n + m + p are numbers such that the total molecular weight of the uncapped portion of the molecule is from about 500 to 25,000 and the molecular weight of the hydrophile is 5 to 35 weight percent and the molecular weight of the hydrophobe is from 65 to 95 weight percent of the total weight of the molecule; X is a hydrocarbon residue containing 2 to 30 carbon atoms, preferably the residue (-CR1R2CR3R4CR5R6-) where R1, R2, R3, R4, R5 and R6 are H, methyl, and mixtures thereof, q is a number from 0 to 1, A4 is an Si R'3 group wherein R' is a C1 to C30 alkyl, a C1 to C30 oxyalkyl, a C6 to C30 aryl group, and mixtures thereof; and (c) the balance water.
