Abstract
A hydrophobic and particulate soil removal composition is provided. The composition can be used for removing organic hydrophobic soils, such as oily or greasy soils, from a laundry item and/or from a hard surface such as an engine part and/or from skin. The composition can be used in a liquid or solid form and can be applied to individual laundry items in the form of a solid stick or liquid spray prior to introduction to the laundry machine. Laundry items can also be contacted in the laundry machine with the pre-spot or pre-treatment composition in the form of an aqueous presoak, preflush, prewash, or other step prior to the cleaning step. The treatment composition can be used as a recirculating liquid stream or bath for the cleaning of hard surfaces. The composition includes an ethoxylate component and a fatty acid ester component.
