ABSTRACT:
A cleaning agent is used to wash surfaces of aluminum products in a cleaning bath. The cleaning agent is a water-soluble acid containing ferric ions. During the cleaning process, the ferric ions are reduced to ferrous ions. The used cleaning agent is sent to an electrolytic tank so that the ferrous ions are subject to the electrolytic oxidation to be converted into ferric ions. The regenerated cleaning agent is returned to the cleaning bath.
