1. A liquid hand dishwashing cleaning composition comprising from about 5% to about 50% by weight of the total composition of a surfactant system, wherein the surfactant system comprises:
A) at least about 40% by weight of the surfactant system of anionic surfactant, wherein the anionic surfactant comprises at least about 50% by weight of the anionic surfactant of alkyl sulfate anionic surfactant, wherein the alkyl sulfate anionic surfactant:
i. has an alkyl chain comprising an average of from 8 to 18 carbon atoms;
ii. comprises branched alkyl sulfate anionic surfactant such that the alkyl sulfate anionic surfactant has an average degree of branching of at least about 15%; and
iii. has an average degree of alkoxylation of less than about 0.5; and
B) an alkyl polyglucoside surfactant, wherein the anionic surfactant and alkyl polyglucoside surfactant are present at a weight ratio of from greater than about 1:1 to about 10:1, wherein the alkyl polyglucoside surfactant is selected from C8-C18 APG, and is a blend of short chain alkyl polyglucoside surfactant having an alkyl chain comprising 10 carbon atoms or less, and long chain alkyl polyglucoside surfactant having an alkyl chain comprising greater than 10 carbon atoms, and wherein the alkyl polyglucoside surfactant has a number average degree of polymerization of from about 0.1 to about 3.0, and
C) from about 10% to about 40% by weight of the surfactant system of a co-surfactant comprising amine oxide, betaine, or combinations thereof.
