Patent ID: 8080508

Claim:
An aqueous hard surface cleaning composition, comprising: (a) an anionic, nonionic, cationic, or amphoteric surfactant, and mixtures thereof; optionally including a quaternary ammonium surfactant, the total amount of said surfactant being present in an amount from about 0.05 to about 15 wt. percent of the composition; (b) at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25° C., said at least one organic solvent present in a solubilizing- or dispersion-effective amount; (c) a chelating agent derived from one or more components of the formula: wherein R is a hydroxyalkyl group having from 1 to about 10 carbon atoms; each R′ is individually selected from the group consisting of hydrogen, unsubstituted or inertly substituted alkyl groups; carbonyl-containing alkyl groups, carboxylate-containing alkyl groups, hydroxyalkyl groups and alkoxy groups; R″ has from 1 to about 10 carbon atoms and is selected from the group consisting of unsubstituted or inertly substituted alkyl groups; carbonyl-substituted alkyl groups, carboxylate-containing alkyl groups, hydroxyalkyl groups and alkoxy groups; or hydrogen; M 1 and M 2 are individually selected from the groups consisting of Na+ and K+, wherein the M 1 has a higher atomic weight than M 2 ; wherein x+y=n and the mole fraction of M 1 is greater than 0.70 to 1; and (d) water.
