Abstract
In a process for removing stains from fabrics by washing in an aqueous medium containing a peroxygen compound and an acylamide activator, extremely small amounts of the activator, e.g., about 5 to 50 ppm., are effective if the medium contains about 100 to 300 ppm of trisodium nitrilotriacetate or ethylene diamine tetraacetic acid sodium salt and an amount of the peroxygen compound representing about 3 to 80 ppm of active oxygen and substantial excess of active oxygen over that stoichiometrically equivalent to the amount of activator.
