The invention relates to a detergent for gentle removal of inks as used for marking in a roll mill, and to markers as used in production for temporary marking. According to the invention, the problem is solved by a detergent which permits the gentle removal of inks or markers from metallic surfaces in the form of a concentrate or a cleaning bath solution containing at least one water-immiscible solvent in an amount of 4 to 200 g/l, at least one anionic and/or nonionic surfactant in an amount of 8-300 g/l, at least one complexing agent in an amount of 1-100 g/l, at least one buffer substance in an amount of 1-100 g/l and at least one water-miscible solvent in an amount of 4-200 g/l in water. 本发明涉及用于温和地除去如在轧机中用于标记的油墨以及如在生产中用于临时标记的标识物的清洁剂。根据本发明，所述目的通过如下的清洁剂实现，该清洁剂允许以浓缩物或清洁浴溶液的形式温和地除去金属表面的油墨和标识物，其在水中包含4至200 g/l量的至少种不能与水混合的溶剂、8至300 g/l量的至少种阴离子型和/或非离子型的表面活性剂、1至100 g/l量的至少种络合剂、1至100 g/l量的至少种缓冲物质和4至200 g/l量的至少种能够与水混合的溶剂。
