Copper is a versatile metal used for many applications. New copper has a rich, shiny finish that oxidizes and creates a green patina when exposed to air. While the oxidation is natural and preferred in some situations, some people would rather keep the shine of new copper. Restoring copper light fixtures can bring back their original beauty.
Instructions
Clean, Remove Dents, Polish
1. Remove existing dirt from fixture. Wipe the piece down with a clean cloth and vinegar. Submerge really dirty pieces for a few hours in a vinegar bath. Do not submerge two different metals. Copper is a relatively soft metal and may travel to the harder metal and plating will occur. Rinse really well, or dip the fixtures in a sodium bicarbonate and water solution to neutralize the acid.
2. Remove dents and dings at this point. Gently tap the outer edges of the dent with a jeweler's peen hammer. Work in slowly towards the center until the dent is flattened.
3. Polish the fixture. Use a polish that is suitable for many . A polish that is not safe for aluminum or other pure metal may contain ammonia or anhydrous products that can cause cracking, etching and premature aging in soft metals. Use a soft cotton cloth and start with a small area. A dark residue appears quickly. Rub the residue in without turning the cloth to a clean side. The copper will begin to shine. Remove the residue. Repeat this process around the piece until all areas are joined. Polish the entire piece.
4. You must repolish some fixtures every few months. Check the polish label.
