Abstract
Improved cleaning compositions are described that are efficient in removing both food and industrial grease, heel marks, and the like from hard surfaces, wherein improved cleaning compositions contain certain nonionic surfactants and quaternary amine salts, when combined with a slightly water-soluble polar organic compound that have a surprising synergistic effect resulting in a marked improvement in the removal of hydrocarbon-containing soils as shown by decreased soaking times required for soil removal.
