Oxidized Sterling Silver: Sterling silver has traditionally been kept as bright and shiny as possible. However, some people enjoy the appearance of oxidized sterling silver, especially when used in jewelry. Oxidized silver has a distinctively smoky appearance. It is dull rather than shiny and may come in black or various shades of gray. Cleaning oxidized sterling silver the same way you would polish normal silver will ruin the oxidization and completely alter the appearance and style of the piece. Silver polish is especially dangerous as it is actually designed to remove oxidization and tarnish.
* Pour the warm water and dishwashing liquid into a bowl big enough to hold your oxidized silver and stir or swirl gently to mix. Use only warm water in this stage; hot water can affect the oxidization.
* Put your silver into the solution in your bowl.
* Wait 10 to 20 minutes until any visible dirt or residue on your silver is softened.
* Remove your oxidized sterling silver from the bowl.
* Dry your silver gently with your soft towel. Do not rub the silver roughly with the towel, as this may remove or damage the oxidization.
Sterling Silver & Gold: Clean using soapy warm water and a soft brush, making sure to rinse well. Never soak over 20 minutes or steam clean, and avoid prolonged sun exposure to prevent fading. For a shiny finish, give the piece a quick once-over with the enclosed polish cloth.
Gold and Silver Plated Jewelry: You can clean gold plated jewelry the same way you clean solid gold jewelry. The only thing to be careful of is not to scratch it. Put a couple drops of dish liquid in warm water. Do NOT use automatic dish liquid because it does contains abrasives. Let the jewelry soak for a few minutes to loosen the dirt. Brush the jewelry with a small, soft brush. I usually save my old toothbrushes for this purpose. You especially want to brush around stones and clasps to remove accumulated body oils and dirt. Then, rinse with water. Dry with paper towels or anything else that’s lint free. Finally, wear your clean, shiny jewelry with pride!
Antique Brass: Clean using soapy warm water and a soft brush, (if needed soak for 5 minutes) making sure to rinse well. And dry well immediately.
