Abstract

Fully diluted hard surface cleaners are disclosed which are particularly effective on cleaning soap scum. The cleaners contain at least 0.45 eq/kg of a dissolved anion which reacts with calcium ion to form an insoluble salt. The cleaners also contain a particular amine oxide, or a different surfactant in conjunction with a solvent. Preferred embodiments include a bleach, which provide for a cleaner which is effective on soap scum and mold and mildew.
