Put 2 tablespoons of baking soda into a bowl, cut a lemon in half, and squeeze a small amount of juice on top of the baking soda. Stir the mixture with a spoon until it forms a soft paste.
Put on rubber cleaning gloves, and smear the baking soda paste over the bronze. Rinse your gloved hands, and buff the metal with a soft cloth. Use moderate pressure and circular strokes. After you buff the item, leave the cleaning paste on for 30 minutes.
Rinse the bronze item with warm running water until it is free of residue, and then dry it with a towel. Use a corner of the towel to reach tight crevices. Inspect the bronze for any remaining discoloration, and repeat the cleaning process if necessary.
