1. A method for cleansing body or face comprising the steps of(a) wetting a cleaning article comprising a substantially dry substrate selected from the group consisting of a pad or a sheet, which substantially dry substrate is impregnated or coated with a dried-down composition that comprises a hydrophilic polyurethane polymer, at least one surfactant and water, wherein prior to drying down the composition, the composition is impregnated into or coated onto the substrate as a wet mixture comprising between about 0.01% and about 90% of a hydrophilic polyurethane polymer; between about 0.05% and about 90% of at least one surfactant; and between about 10% and about 85% water, where percentages are based on the total weight of the composition prior to drying down; and(b) applying the wetted cleaning article to the body or face as desired. 2. The method of claim 1, wherein the composition further comprises a component selected from the group consisting of organic fillers, inorganic fillers, abrasives, moisturizers, detergents, fragrances, dyes, flame retardants, antihistamines, antibiotics, antifungal agents, sunscreen agents, anti-acne drugs, corticosteroids, and mixtures of these.3.

The method of claim 8, wherein when the substantially dry substrate is wetted the composition is released therefrom over a period of time.14. The method of claim 8, wherein when the substantially dry substrate is wetted and the article is used for cleaning the hydrophilic polyurethane does not dissolve.15. A method for cleansing body or face comprising the steps of(a) wetting a cleaning article comprising a substantially dry substrate selected from the group consisting of a pad or a sheet, which substantially dry substrate is impregnated or coated with a dried-down composition that comprises a hydrophilic polyurethane polymer, at least one hydrophilic non-polyurethane polymer selected from the group consisting of of monoalkyl esters of polymethyl vinyl ether/maleic acid polymers, quarternized copolymers of vinylpyrrolidone and dimethylaminoethyl methacrylate, vinylpyrrolidone/vinyl acetate copolymers, alkylated vinylpyrrolidone polymers, polyvinyl pyrrolidone, polyethylene glycols, polyacrylate copolymers, polyvinylidene dichloride, and mixtures thereof, at least one surfactant; and water, wherein prior to drying down the composition, the composition is impregnated into or coated onto the substrate as a wet mixture comprising between about 0.01% and about 90% of a hydrophilic polyurethane polymer; between about 0.01% and about 90% of a hydrophilic non-polyurethane polymer selected from the group consisting of monoalkyl esters of polymethyl vinyl ether/maleic acid polymers, quarternized copolymers of vinylpyrrolidone and dimethylaminoethyl methacrylate, vinylpyrrolidone/vinyl acetate copolymers, alkylated vinylpyrrolidone polymers, polyvinyl pyrrolidone, polyethylene glycols, polyacrylate copolymers, polyvinylidene dichloride, and mixtures thereof; between about 0.05% and about 90% of at least one surfactant; and between about 10% and about 85% water, where percentages are based on the total weight of the composition prior to drying down, and(b) applying the wetted cleaning article to the body or face as desired. 16.
