ABSTRACT:
An aqueous metal cleaning composition is provided which comprises an alkalinity providing agent such as alkali metal carbonate and/or bicarbonate salts and a low foaming surfactant. The aqueous cleaning solution has specific foam height and foam collapse characteristics, and provides for substantially complete phase separation of a contaminant phase from the aqueous cleaning composition such that there is substantially no aqueous phase drag out into the contaminant phase; and the contaminant phase can be removed easily, and the aqueous cleaning solution can be recovered and reused.
