Claims40
A process for cleaning and disinfecting a substrate contaminated with living microorganisms using a two-part liquid composition comprising components (A) and (B), wherein component (A) comprises a disinfectant medium comprising from about 5% to about 60% by weight of the disinfectant medium of peracetic acid, acetic acid, hydrogen peroxide and from about 0.5% to about 2% by weight of the disinfectant medium of sulfuric acid, wherein the pH of the disinfectant medium is from about 1 to about 8;
- and component (B) comprises a supplemental medium comprising an enzymatic cleaner, a non-enzymatic cleaner, a corrosion inhibitor and a chelator;
- wherein the non-enzymatic cleaner comprises an alkanol amine, a polyalkylene glycol, an alkyl diproprionate, an alkyl dialkylamine oxide, or a mixture of two or more thereof, wherein the volumetric ratio of (a) to (B) is in the range from about 5:1 to 1:5;
- the process comprising:
- contacting the substrate with the supplemental medium (B) and the disinfectant medium (A) to clean and disinfect the substrate.
