Claim:
A method of cleaning a textile load comprising polyester items in a professional laundry machine, wherein the method comprises repeatedly subjecting the polyester items to main-wash, rinse and optionally pre-wash cycles, wherein the load is contacted during a rinse cycle with a liquor containing an external structurant and a soil release polymer, wherein the level of soil release polymer per kilogram of load is from about 0.01 to about 0.075 grams, wherein the external structurant is a polymeric structurant, wherein the polymeric structurant is a polymeric gum material selected from the group consisting of pectine, alginate, arabinogalactan (gum Arabic), carrageenan, gellan gum, xanthan gum, guar gum, and mixtures thereof, wherein said soil release polymer has the following formula: wherein: each R 1 moieties is a 1,4-phenylene moiety; the R 2 moieties are each selected from the group consisting of ethylene moieties, 1,2-propylene moieties, 1,2butylene moieties, 1,2hexylene moieties, 3-methoxy-1,2propylene moieties or mixture thereof, provided that said R 2 are not exclusively 1,2 butylene moieties, 1,2hexylene moieties, 3-methoxy-1,2propylene moieties or mixture thereof; the R 3 moieties are each selected from the group consisting of substituted 1,3-phenylene moieties having the substituent at the 5 position; the R 4 moieties are R 1 or R 3 moieties, or mixtures thereof; each X is C1-C4 alkyl; each n is from 12 to 43; when w is 0, u+v is from 3 to 10; when w is at least 1, u+v+w is from 3 to 10, and wherein said soil release polymer is provided is an additive.
