Abstract
Hard surface cleaning compositions which cause little or no vinyl staining comprise from about 1% to about 60% of an amine oxide detergent surfactant having the formula R.sup.1 R.sup.2 R.sup.3 NO, wherein R.sup.1 has from about 8 to about 30 carbon atoms, and R.sup.2 and R.sup.3 each individually has from about 1 to about 18 carbon atoms; an aqueous carrier liquid; an amine; and no more than about 2% anionic surfactant. At least a portion of the amine is protonated, and the molar ratio of protonated amine to amine oxide is at least 0.1:1.
