The surface of a metal body is descaled by subjecting the body to electrolysis in a bath of an electrolyte and also to ultrasonic agitation. The electrolysis comprises applying a pulsed electric potential to the metal body while the metal body is present in the bath, and the ultrasonic agitation is carried out while the body is still wet after the electrolysis.
