PROBLEM TO BE SOLVED: To provide a contamination-proof detergent composition for a hard surface giving contamination-proof property to a surface of a material to a bath room and a bath tub constituted by a plastic material, and further bath strips such as a stool, a bucket and a duckboard, relaxing deposition of a contaminant such as soap dregs, a skin fat and minerals (scale) such as calcium and magnesium, i.e., a hard water component of tap water and well water and capable of easily washing/removing the contaminant even if the contaminant of these is deposited, a washing material impregnated with the composition, and a washing method using those. SOLUTION: The contamination-proof detergent composition for the hard surface is characterized in that it contains (A) 0.5-60 mass% of an ethylene oxide/propylene oxide/ethylene oxide copolymer, (B) 0.1-15 mass% of a surfactant, (C) 0.1-15 mass% of a chelating agent, (D) 0.1-15 mass% of a water-soluble solvent and (E) remaining mass% of water. Further, the washing method using the contamination-proof detergent composition for the hard surface or the washing material impregnated with it is provided. COPYRIGHT: (C)2008,JPO&INPIT
