TWO STEP METHOD OF CLEANING, SANITIZING, AND RINSING A SURFACE

摘要

Methods employing detergent compositions comprising phosphinosuccinic acid oligomers (PSO) in combination with a sanitizing rinse aid are disclosed. The methods beneficially clean, sanitize and rinse a surface in an efficient two-step process. The detergent compositions employ phosphinosuccinic acid adducts, namely mono-, bis- and oligomeric phosphinosuccinic acid (PSO) derivatives, in combination with an alkalinity source and optionally polymers and/or surfactants. The sanitizing and rinsing compositions employ peroxycarboxylic acid compositions in combination with a nonionic defoaming and wetting surfactant.

1. A two-step method of cleaning, sanitizing and rinsing a surface comprising:
(a) cleaning a surface with a detergent composition comprising: an alkalinity source selected from the group consisting of an alkali metal carbonate, alkali metal hydroxide, alkali metal silicate, alkali metal metasilicate, and combinations thereof; a phosphinosuccinic acid adduct comprising a phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid adducts; and (b) sanitizing and rinsing the surface with a sanitizing rinse composition comprising: a C1-C22 peroxycarboxylic acid; a C1-C22 carboxylic acid; hydrogen peroxide; and a nonionic defoaming and wetting surfactant(s).
