Loosen up the corrosive buildup by carefully rubbing the oxidized area with fine grit sandpaper. Avoid rubbing too vigorously, which can scratch the metal surface.
Cut a lemon in half, and squeeze its juice into a bowl. Dip a cotton ball into the lemon juice, and sponge it onto the metal. Remove as much buildup as possible.
Mix 2 parts baking soda and 1 part water in a suitable container until a thick paste forms.
Apply the paste to the oxidized area in a thick layer, and then allow the paste to dry completely.
Rub the dried paste away using a paper towel. The rest of the corrosion should peel off with the paste. Remove any remnants of paste and clean the surface using a fresh cloth.
