Enzymatic caustic free detergent compositions for cleaning dairy processing systems

A method of cleaning a dairy processing system comprising:

• circulating a first dose of a cleaning composition to the dairy CIP system;
• wherein the cleaning composition comprises a serine protease enzyme;
• a surfactant comprising an alkylpolyglucoside, an EO-PO block copolymer, an alcohol alkoxylate, and/or mixtures thereof;
• a water conditioning agent comprising an aminocarboxylic acid, acrylic acid, polycarboxylic acids, salts of the foregoing, and/or mixtures thereof;
• a C2-C10 polyol;
• a buffer system;
• and water;
• wherein the pH of the cleaning composition is between about 6 and about 11;
• monitoring the cleaning composition during the cleaning of the dairy processing system;
• adjusting the concentration of the cleaning composition by adding additional water and/or an additional dose of the cleaning composition to the dairy processing system.
