[ We claim:] [1.] A method of cleaning soil, without substantial residue remaining, from a hard surface, comprising applying to said surface an aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:(a) about 1-50% 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) about 0.001-2% of at least one semi-polar nonionic surfactant, said surfactant having the structure: [ STR 13 ] wherein R.sup.1 is C.sub.5-20 alkyl, R.sup.2 and R.sup.3 are both C.sub.1-4 alkyl, [ STR 14 ] or --(CH.sub.2).sub.p -OH, although R.sup.2 and R.sup.3 do not have to be equal, and n is 1-5, and p is 1-6;(c) about 0.01-2% of a buffering system which comprises ammonium or alkaline earth carbamate, wherein the total amount of semi-polar nonionic surfactant and any optional surfactants does not exceed 2%; and(d) the remainder as substantially all water; and(e) removing said soil and soil cleaner from said surface.
