Abstract

Composiciones acuosas que comprenden ciertos aminoácidos tales como ácido poliaspártico o copolímeros de ácido aspártico/ácido glutámico, cuando son parcialmente protonadas a un pH de 7 o por abajo del mismo, limpian efectivamente superficies de metales ferrosos poniendo en contacto dichas superficies con las composiciones.
