Abstract:
A method of removing a complex soil from a hard surface, the method comprising:(a) contacting the hard surface and the complex soil with a cleaner composition comprising: (i) about 0.003 to 35 wt % of one or more nonionic surfactants; (ii) about 0.0005 to 35 wt % of one or more silicone surfactants, the weight ratio of the nonionic surfactant to the nonionic silicone surfactant is such that there are about 0.1 to about 10 parts by weight of the nonionic surfactant per each part of the silicone surfactant; and (iii) about 0.003 to 35 wt % of one or more anionic surfactants; and (iv) about 0.001 to 20 wt % of one or more hydrotropes, sufficient to maintain the composition as a uniform solution to form removed soil; (b) forming removed complex soil; (c) removing the composition and complex soil, the complex soil comprising an inorganic solid phase dispersed in an organic phase.
