To provide a detergent for a molding machine which has higher productivity.SOLUTION: A detergent for a molding machine which cleans an inside of a molding machine and is made of a resin contains 0.2 to 5 pts.wt. of polyvinyl pyrrolidone with respect to 100 pts.wt. of polysulfone. Productivity, a cleaning effect and a release effect of the detergent for the molding machine can be improved. The detergent may contain 0.03 to 1 pt.wt. of a compound having a phosphite structure and a hindered phenol structure.SELECTED DRAWING: Figure 1 【課題】より生産性の高い成形機用洗浄剤を提供すること。【解決手段】成形機の内部を洗浄するための樹脂製の洗浄剤であって、ポリサルフォン１００重量部に対して、ポリビニルピロリドン０．２～５重量部を含有した成形機用洗浄剤である。成形機用洗浄剤の生産性の向上、洗浄効果の向上および離型効果の向上を図ることができる。さらに、フォスファイト構造とヒンダードフェノール構造とを有する化合物を０．０３～１重量部含有してもよい。【選択図】 図１
