Can Aluminium Be Tarnished?
Yes, aluminium can be tarnished. Tarnishing occurs when the surface of a metal corrodes or oxidizes, resulting in a dull or discolored appearance. Although aluminum has a natural oxide layer that helps protect it from corrosion, this layer can be damaged or removed, making the metal more susceptible to tarnish. Tarnish on aluminum can typically be removed by gently polishing the surface with a mild abrasive and a soft cloth.
