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.
L'invention porte sur un procédé d'élimination des salissures contenant des huiles et des graisses des surfaces de traitement d'aliments. Ledit procédé consiste à composer une solution de nettoyage à partir d'un concentré à deux constituants dont le premier consiste en une source alcaline et de l'eau, et le deuxième, en un composé d'ammonium quaternaire. Une fois préparée, la composition, qui comporte une majeure partie d'eau, de 100 à 20 000 ppm de composé d'ammonium quaternaire, et une source alcaline dans une concentration lui conférant un pH compris entre environ 10 à 14, s'utilise par application sur les surfaces de préparation d'aliments. La susdite composition peut également contenir un chélateur et un deuxième agent détersif non ionique ou anionique.
