We claim: 1. A method of making a cleaning article comprising the steps of: (a) forming a wet mixture by mixing water, at least one surfactant, a hydrophilic polyurethane polymer and at least one hydrophilic non-polyurethane polymer selected from the group consisting of monoalkyl esters of polymethyl vinyl ether/maleic acid copolymers, 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; (b) impregnating and/or coating a substrate with the wet mixture in such manner that the wet mixture does not form a hydrophilic foam, (c) drying the impregnated and/or coated substrate. 2. The method of claim 1, wherein the cleaning article is impregnated and/or coated with a composition comprising (a) between about 0.01% and about 90% of a combination of a hydrophilic polyurethane polymer and at least one hydrophilic non-polyurethane polymer; (b) between about 0.05% and about 90% of at least one surfactant; and (c) between about 10% and about 85% water, where percentages are based on the total weight of the composition. 3. The method of claim 1, wherein the cleaning article is impregnated and/or coated with between about 1% and about 45% of a combination of a hydrophilic polyurethane polymer and at least one hydrophilic non-polyurethane polymer polymer; between about 20% and about 60% of at least one surfactant; between about 20% and about 60% water; and 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, where percentages are based on the total weight of the wet mixture. 4. The method of claim 1, wherein the total amount of the combination of hydrophilic polyurethane polymer and at least one hydrophilic non-polyurethane polymer is between about 1% and about 45%, where percentages are based on the total weight of the wet mixture. 5. The method of claim 1, wherein the surfactant is an anionic surfactant, a non-ionic surfactant, or a mixture of both. 6. The method of claim 1, wherein the surfactant is present in an amount between about 20% and about 60%, where percentages are based on the total weight of the wet mixture. 7. The method of claim 1, wherein the water is present in an amount between about 20% and about 60%, where percentages are based on the total weight of the wet mixture. 8. The method of claim 1, wherein the wet mixture 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. 9. The method of claim 1, wherein the wet mixture comprises between about 25% and about 35% of a combination of a hydrophilic polyurethane polymer and at least one hydrophilic non-polyurethane polymer selected from the group consisting of monoalkyl esters of polymethyl vinyl ether/maleic acid copolymers, 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 20% and about 60% of at least one surfactant; between about 20% and about 60% water; and 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, where percentages are based on the total weight of the wet mixture.
