Hydrophobic and particulate soil removal composition and method for removal of hydrophobic and particulate soil

A method for removing hydrophobic and particulate soil from laundry items, the process comprising steps of:

• (a) contacting a soiled laundry item with a pre-treatment composition comprising:
• (i) an effective treating amount of ethoxylate mixture containing ethoxylate groups and having the formula:
• R1—(OC2H4)m—OH
• wherein R1 contains about 6 to about 26 carbon atoms and m is an average value of 2 or less;
• and
• (ii) an effective treating amount of a fatty acid ester component having the formula:
• R3—CO2—R4
• wherein R3 is an alkyl group having about 6 to about 26 carbon atoms and R4 is an alkyl group having about 1 to about 6 carbon atoms;
• (iii) wherein the hydrophobic and particulate soil removal composition comprises a weight ratio of ethoxylate component to fatty acid ester component of between about 1:4 and about 4:1;
• wherein the soiled article comprises an article. soiled by at least one of motor oils, asphaltenes, hydrocarbon tars, coal tars, petroleum greases, transmission fluids, hydraulic oils, and hydraulic greases;
• and
• (iv) an effective amount of a processing aid to provide freeze stability;
• and
• (b) laundering the treated laundry item with an aqueous laundry detergent.
