Abstract:
The invention provides methods of cleaning including the use of a soil release polymer. In some embodiments, the soil release polymer can be included in a neutral to low alkalinity prewash or main wash that is substantially free of hydroxide-based alkalinity. In some embodiments, the soil release polymer can be included in a neutral to low alkalinity prewash that is substantially free of hydroxide-based alkalinity, followed by an alkaline main wash with any alkalinity source.
