ABSTRACT:
The invention is a method of removing soils containing oils and fats from food processing surfaces. The method includes the steps of formulating a wash composition from a two-part concentrate. The concentrate first part includes a source of alkalinity and water. The concentrate second part includes a quaternary ammonium compound. After formulation, the wash composition has a major portion of water, from about 100 ppm to 20,000 ppm of quaternary ammonium compound, and an alkali source present in a concentration to provide a pH of from about 10 to 14. After formulation, the wash composition may be used by applying it to the food processing surface. Optionally, the wash composition may also include a chelating agent and a second nonionic or anionic detersive agent.
