The composition of this invention is a stabilized acidic bleaching composition comprising an aqueous solution of a source of source of unipositive chlorine ion, a chlorine stabilizing agent, and an acidic buffer to stabilize the pH of the bleaching composition in the range from about 2 to 6.5, wherein the chlorine stabilizing agent and the source of source of unipositive chlorine ion are in a molar ratio of greater than about 1:1. Methods are described for removal of lime scale from a hard surface controlling microbial activity as well as reducing malodor by applying the composition of this invention.
La présente invention concerne une composition de blanchiment acide stabilisée contenant une solution aqueuse d'une source d'émission d'ions de chlore unipositifs, un stabilisateur de chlore ainsi qu'un tampon acide permettant de stabiliser le pH de la composition de blanchiment dans une plage comprise entre 2 et 6,5, le stabilisateur de chlore et la source d'émission d'ions de chlore unipositifs ayant un rapport molaire supérieur à environ 1:1. Cette invention concerne par ailleurs des procédés permettant d'éliminer les dépôt de tartre d'une surface dure de manière à juguler l'activité microbienne et réduire les mauvaises odeurs en appliquant la composition de cette invention.
