Abstract:
1. An acidic hard surface cleaning compositions comprising: about 0.05-1% wt. of one or more anionic surfactants; about 0.05-7.5% wt. of a nonionic surfactant constituent which said constituent preferably both about 0.5-2.5% wt. of a first alcohol ethoxylate nonionic surfactant derived from monobranched alkoxylated C about 0-5% wt. of one or more further surfactants selected from amphoteric or zwitterionic surfactants, but which expressly exclude cationic surfactants; about 0.01-5% wt. of an organic solvent constituent; about 0-5% wt. of an alkanolamine; about 2-15% wt. of an acid constituent which comprises a ternary acid system comprising each of: sulfamic acid, formic acid and oxalic acid in a respective weight ratio of sulfamic acid:formic acid:oxalic acid of 1-8:1-5:1-3; optionally one or more further constituents which are directed to improving one or more aesthetic or functional features of the composition, which may be present in a cumulative amount of not in excess of about 10% wt. of the total of the composition of which they form a part, at least 85% wt. water; wherein the compositions have a pH of about 2 or less and further wherein the compositions exhibit good removal of greasy stains and concurrently also exhibit good soapscum removal from hard surfaces.
