Bronze or Copper Patinated Objects

Dust off your sculpture regularly with a feather duster, a synthetic electrostatic duster, or a soft clean cloth or microfiber towel. If the object has developed a grimy film, more intense cleaning may be necessary. The best way to clean bronze or copper patinated sculptures, is with a mild soap and water.

Never use caustic chemicals containing ammonium, chlorine, solvents, or adhesive removers. Avoid paper towels, squeegees, steel wool, scouring pads, and the like.

For cleaning a bronze or copper patinated sculpture, add a few drops of a mild household soap in a bowl of water. Just add enough soap to make bubbles in the water because all you really need to do is loosen the dirt from the surface. Then dampen a clean cloth and gently wipe down the object. If the piece has a lot of nooks and crevices, a soft paint brush might be useful.

Once the sculpture is clean, rinse out the cloth and wipe down the object with clear water to remove the soap residue. Use the paint brush with clear water to clean areas that are hard to reach. Next, carefully dry the sculpture with a soft dry cloth or microfiber towel.
