Abstract:
A method of cleaning, marble or lacquered surfaces with a composition having a pH of from 6 to 9, said composition comprising from:(a) 5% to 85% of a surfactant;(b) 0.1% to 20% of an organic polycarboxylate builder wherein the highest LogKa, measured at 25.degree. C./0.1M ionic strength is between 3 and 8, wherein the sum of the LogKCa+LogKMg, measured at 25.degree. C./0.1M ionic strength is higher than 4, and wherein LogKCa=LogKMg units, measured at 25.degree. C./0.1M ionic strength; and(c) positive divalent ions in an amount sufficient to saturate the builder in the composition.said method comprising the step of contacting said surface with an amount of said composition effective to clean said surface, and optionally rinsing said composition from said surface.
