Abstract
A composition capable of removing hydrophobic soils is provided that includes a nonionic surfactant; a very slightly water soluble organic solvent; water; and an optional additive. Improved hydrophobic soil removal is achieved wherein an amount of the slightly water soluble solvent with respect to an amount of the surfactant is sufficient to achieve a haze point in the composition.
