Abstract
The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.
