A highly aqueous liquid acidic hard surface treatment composition having a pH of about 3.5 or less which necessarily comprises:
0.001 - 3.5%wt. of an acid constituent which comprises one or more organic acids, but which preferably comprises lactic acid and one or more further organic acids acids, and especially preferably wherein the acid constituent consists solely of lactic acid;
an organic solvent constituent, desirably selected from a monohydric alcohol and/or a glycol ether;
an anionic surfactant constituent, desirably a sulfur atom containing anionic surfactant constituent, such as of the sulfate or sulfonate types;
a nonionic surfactant constituent;
optionally a cosurfactant constituent, including one or more nonionic, cationic, amphoteric or zwitterionic surfactants;
optionally one or more further constituents selected coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents including one or more thickeners, pH adjusting agents and pH buffers including organic and inorganic salts, optical brighteners, opacifying agents, hydrotropes, abrasives, and preservatives, as well as other optional constituents known to the art;
and the balance, water, wherein water comprises at least 80%wt. of the composition.
The highly aqueous liquid acidic hard surface treatment composition may be used as such, or may be used to impregnate absorbent substrates to form wipe articles.
Methods for the use of said highly aqueous liquid acidic hard surface treatment compositions, in cleaning and/or disinfection of hard surfaces are also disclosed.
