(i) providing an aqueous liquid composition comprising the following components:
(a) at least one soil release polymer,
(b) at least one surfactant,
(c) at least one water-soluble polymer,
(d) optionally at least one washing booster,
(e) at least one perfume component, and
(f) optionally at least one adjunct detergent ingredient;
(ii) applying the composition of step (i) onto a surface such that it forms a layer on said surface;
