Abstract:
A method of cleaning a hard surface, said method comprising:spraying a non-corrosive, low-fuming composition having a viscosity ranging from about 30 to about 70 Cps at 25Â° C. onto the surface, said composition comprising: (a) from about 3.0 wt-% to about 20.0 wt-% of at least one detergent builder selected from tripolyphosphates; (b) from about 0.1 wt-% to about 20 wt-% of an alkalinity source effective to provide a pH of from about 10 to about 14 to said composition; c) from about 0.0 wt-% to about 5.0 wt-% of at least one thickening agent to promote adhesion of said thickened, non-corrosive composition to the surface upon application; d) from about 0.0 wt-% to about 5 wt-% of fatty acid stabilizer to maintain a homogenous mixture of said at least one detergent builder, at least one thickening agent, and alkalinity source; e) from about 0.0 wt-% to about 5.0 wt-% of an anionic surfactant effective to provide detergency to the thickened, non-corrosive low-fuming composition said anionic surfactant selected from the group consisting of an alkyl sulfate, an alkyl sulfonate, a disulphonate compound, an alkyl ether sulfate, an alkyl ether sulfonate, an alkyl aryl sulfonate, and mixtures thereof; (f) from about 0.0 wt-% to about 2.0 wt-% of a metal ion chelator; and (g) a balance of water; wherein the composition is substantially free of chlorine.
