1. A hard surface cleaner containing(i) an alkylpolyglycoside surfactant composition having an HLB in the range of about 10 to about 16, in which the alkyl group contains from about 6 to about 20 carbon atoms, said alkyl polyglycoside surfactant composition comprising a mixture of:

  • (a) an alkylpolyglycoside component having a non-Flory distribution of glycosides containing a degree of polymerization of 2 and higher in progressively decreasing amounts, in which the amount by weight of polyglycoside having a degree of polymerization of 2, or mixtures thereof with a polyglycoside having a degree of polymerization of 3, predominate and having an average degree of polymerization of about 1.8 to about 3; and

    (b) at least one other glycoside component having an average alkyl chain length less than the average alkyl chain length of component (a); and

    wherein the alkylpolyglycoside component (a) is an at least binary component and the glycoside component (b) is an alkylpolyglycoside at least binary component and each of the binary components (a) and (b) is present in the mixture in relation to the average carbon chain length in an amount to provide the alkylpolyglycoside surfactant composition with an average carbon chain length of about 9 to about 14 and an HLB in the range of about 10 to about 16; and

    (ii) at least one hard surface cleaner adjuvant selected from the group consisting of a co-surfactant;

    a conditioning agent;

    a hydrotrope;

    a solvent;

    a filler;

    a coloring agent;

    a dye;

    a brightening agent;

    a fragrance;

    a preservative;

    a consistency regulator;

    a polishing agent; and

    a humectant.
