PROBLEM TO BE SOLVED: To obtain an improved detergent capable of surely cleaning tiles and flagstones known as fine stoneware, which have a roughened surface and have been provided with contour work when used, at a concentration level equal to or lower than the concentrations of conventional detergents. SOLUTION: An aqueous detergent concentrate uses a nonionic, anionic or an amphoteric surface active agent as the base and uses or does not use conventional auxiliaries and additives, and comprises a quaternary alkoxylated amine compound as the cleaning accelerator. Further, the aqueous detergent concentrate comprises 0.1-5 pts.wt. alkoxylated amine compound of the formula: [R1, R2, R3, R4N]+X- as the cleaning accelerator. Exemplary compounds of the formula include coco-pentaethoxymethylammonium methosulfate and/or ethyl-bis-(polyethoxyethanol)-tallow ammonium ethosulfate.
