A cleaning agent, a composition including the agent, and methods of forming and using the agent and composition are disclosed. The agent is formed by combining an organic acid and an amine in the presence in a base to form a compound for chelating copper ions. The composition optionally includes diluents, surfactants, sequestering agents, corrosion inhibitors and/or thickening agents. La présente invention comprend un agent nettoyant, une composition comprenant l'agent et des procédés de formation et d'utilisation de l'agent et de la composition. L'agent est formé en combinant un acide organique et une amine en présence d'une base pour former un composé destiné à chélater les ions cuivre. La composition comprend facultativement des diluants, des agents tensioactifs, des agents séquestrants, des inhibiteurs de la corrosion et/ou des épaississants.
