Many of those cherished farm bells were passed down through generations; however, when cast iron is exposed to the elements, rust develops over time. Restoration requires rust removal and coating with a protectant.
Things You Will Need
-
Brush your cast-iron bell using a wire brush to remove loose rust.
-
Submerge the bell in diluted phosphoric acid to loosen rust, and lightly etch to expose a clean, fresh surface. Follow manufacturer's instructions for dilution rates and submersion times. Use the minimum submersion time to avoid unnecessary etching of the iron.
-
Remove the bell from the phosphoric acid solution, and brush with a stiff bristle brush or a wad of aluminum foil.
-
Mix approximately 1/2 cup of baking soda in a gallon of water. Rinse the farm bell inside and out thoroughly with the baking soda solution to neutralize any phosphoric acid residue.
-
Rinse the bell with clear water and allow to dry thoroughly.
-
Apply two coats of alkyd rust-inhibitive primer paint to the bell. Allow to dry between coats according to the manufacturer's directions.
-
Paint the restored farm bell with a coat of alkyd enamel paint.
