A detergent composition for metal product, which contains an amine (component A) represented by a general formula (I), a salt (component B') of a dicarboxylic acid (component B) represented by a general formula (II): HOOC—R—COOH (II) and the amine (component A), a salt (component C′) of a monocarboxylic acid (component C) represented by a general formula (III): R—COOH (III) and the amine (component A), a nonionic surfactant (component D) represented by a general formula (IV): R—O-{(EO)n/(PO)m}-H (IV), and water (component E) and has a pH of more than 7 and 10 or less. The detergent composition for metal product exhibits excellent detergency and metal corrosion suppressing performance.

Detergent composition for metal product and method for cleaning metal product using said detergent composition

The present invention provides: a rust inhibitor that has excellent rust inhibiting and anti-corrosive properties, not only on iron members, but also on non-iron metal members, and can prevent rust and corrosion over long periods; a rust inhibitor composition that contains the rust inhibitor, a coating formation material; a coating obtained from the rust inhibitor, the rust inhibitor composition, or the coating formation material; and a metal component that comprises the coating. This rust inhibitor contains at least one compound represented by a Chemical Formula (1). (In the formula: Ris a hydrogen atom or an aliphatic hydrocarbon group with a carbon number of 1-33; Ris an aliphatic hydrocarbon group with a carbon number of 1-33; the total carbon number of Rand Ris 1-34; X is a single bond or an aliphatic hydrocarbon group with a carbon number of 1-5; either Aor Ais &#x2014;OH; and the other is &#x2014;O&#x2014;CH&#x2014;CH(OH)&#x2014;CHOH or &#x2014;O&#x2014;CH(&#x2014;CH&#x2014;OH).)
