Final answer:
To remove corrosion from clad surfaces, use a metal polish with lactic, citric, or phosphoric acid to dissolve and remove the corrosion.

To remove corrosion from clad surfaces, the corroded areas should be hand polished with a metal polish that contains lactic, citric, or phosphoric acid. These acids help to dissolve and remove the corrosion, restoring the surface to its original state. It is important to use a metal polish specifically designed for the type of metal being cleaned to prevent damage to the surface.
