Abstract

Ferrous surfaces, e.g. carbon or low alloy steel, are cleaned or pickled using 2 to 10% by weight of isomalic acid at 15 to 90 DEG C. When copper is also present as e.g. in the cleaning of boilers ammonia and an oxidizing agent, e.g. hydrogen peroxide, may be used with the isomalic acid. Hydrochloric acid may also be present.
