Abstract

Compositions for use as soil removing agents in the food processing industry are disclosed. Food soiled surfaces in food manufacturing and preparation areas can be cleaned. The compositions are preferably manufactured in the form of a solid block or powder concentrate which is diluted with water and used. The cleaning materials are made in a one or two part system which are diluted with a diluent source and mixed prior to use. The products contain high quality cleaning compositions and use a variety of active ingredients. The preferred materials, in a one or two part system, contain detergent compositions, enzymes that degrade food compositions, surfactants, low alkaline builders, water conditioning (softening) agents, and optionally a variety of formulary adjuvants depending on product form.
