A cleaning agent of sulfamic acid-hydroxycarboxylic acid system is provided, which has the capability of preventing metal elution from metal products to be cleaned and hydrogen embrittlement of the metal products. This cleaning agent comprises sulfamic acid and at least one of hydroxycarboxylic acids, and a compounding ratio (weight ratio) of sulfamic acid : at least one of hydroxycarboxylic acids is (60~95) : (40~5), and preferably (80~95) : (20~5). In particular, when citric acid and malic acid are used as the hydroxycarboxylic acids, and a compounding ratio (weight ratio) of sulfamic acid : citric acid : malic acid is (80~95) : (10~2.5) : (10~2.5), it is possible to provide excellent performance in preventing metal elution and hydrogen embrittlement as well as high detergency.

L'invention concerne un détergent à base d'acide sulfamique/acide hydrocarboxylique utilisé pour nettoyer un produit métallique tout en empêchant ce produit de libérer un métal et de souffrir de fragilisation par l'hydrogène. Ledit détergent comprend un acide sulfamique et au moins un acide hydrocarboxylique dans une proportion de (60 à 95)/(40 à 5) en poids, de préférence (80 à 95)/(20 à 5) en poids. Lorsque le détergent comprend, en particulier, un acide citrique et un acide maléique comme acides hydrocarboxyliques en quantités telles que la proportion acide sulfamique/acide citrique/acide maléique est de (80 à 95)/(10 à 2,5)/(10 à 2,5) en poids, ledit détergent possède une propriété détergente élevée, et un effet de prévention de fragilisation par l'hydrogène et de libération de métal accrus.
