Abstract
A novel approach to the method of removing and preventing redeposition of protein soils on surfaces using sugar esters is disclosed. Protein deposition and streaking and spotting are common on machine washed dishes. Applicants have found a new method of recycling a sump water composition in an automatic dish machine from a first cleaning cycle into subsequent cleaning cycles using a protein-removing/anti-redeposition agent that can remove and prevent redeposition of protein soils on ware washed surfaces.
