摘要： A degreasing method for descaling or removing laser scales from iron-containing metal part surface by treating the iron-containing metal part surfaces that is optionally tainted with laser scales with an aqueous solution containing at least one type of highly water-soluble and complexed with Fe ions carboxylic acid, at least one type of salt of at least one type of carboxylic acid exhibiting the same action and at least one type of fatty amine ethoxylate, wherein the solution is buffered, the Fe ions are carried into the solution and at least partially complexed, increasing the pH value of the solution for descaling with respect to at least one type of carboxylic acid. The entire concentration of carboxylic acids and the salts thereof is increased for descaling by 2 to 20% by weight.
