  • METHOD OF CLEANING BEER KEGS, BREWERY, WINERY AND DAIRY PROCESS EQUIPMENT
    Publication number: 20130000681
    Abstract: A method for cleaning used storage or processing liquid containers employing an aqueous solution of phosphoric acid, nitric acid and one or more surfactants, e.g., a detergent and/or wetting agent. Preferably, the aqueous cleaning solution has a total nitric acid content of 12 wt % or less. Complete cleaning can be achieved without using any caustic. The cleaning solution can be recycled repeatedly to clean multiple containers on numerous occasions over a period of time, e.g., several weeks.
