Abstract: The invention provides an aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:(a) an effective amount of at least one organic solvent with a vapor pressure of at least 0.001 mm Hg at 25.degree. C., and mixtures of such solvents;(b) an effective amount of at least one semi-polar nonionic surfactant, said surfactant having the structure: ##STR1## wherein R.sup.1 is C.sub.5-20 alkyl, R.sup.2 and R.sup.3 are both C.sub.1-4 alkyl, or --(CH.sub.2).sub.p --OH, although R.sup.2 and R.sup.3 do not have to be equal, and p is 1-6;(c) an effective amount of a buffering system which comprises a nitrogenous buffer which will result in a pH of greater than 6.5; and(d) the remainder as substantially all water.

Abstract: The invention provides an aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:(a) an effective amount of a solvent selected from C.sub.1-6 alkanol, C.sub.3-24 alkylene glycol ether, and mixtures thereof;(b) an effective amount of at least one nonionic surfactant;(c) an effective amount of a buffering system which comprises a nitrogenous buffer selected from the group consisting of:ammonium or alkaline earth carbamates, guanidine derivatives, alkoxylalkylamines and alkyleneamines; and(d) the remainder as substantially all water.

Abstract: This invention provides a thickened aqueous hard surface cleaner composition comprising colloidal alumina as the thickener in an aqueous cleaner which comprises a surfactant, electrolyte/buffer, soap and organic solvent system. These cleaner composition systems, which are the fluent, all-purpose type of cleaners, have surprising properties when thickened with the colloidal alumina. Such cleaners when thickened with colloidal alumina have a smoothly flowable or plastic consistency, and in their most preferred form, are pourable at room temperature, which consistency is not thixotropic in nature.
