All sterling silver will eventually oxidize and tarnish unless it has been finished with a protective layer. The good new is if it does tarnish, you can still restore it luster with proper polishing. The easiest way to clean silver is with a clean soft cloth. You can also prevent silver from tarnishing by just storing it away after each usage. Even a simple Zip-lock bag will be adequate, to keep all the air and light from tarnishing the Silver.
 
When clean silver, you need to be very careful not to break the chain as silver is extremely pliable. Just like gold, silver is a very soft metal. You can scratch it just by rubbing it too vigorously. Also, never use a tissue, paper or tissues have wood fibers which can cause tiny scratches on the surface of your Sterling Silver jewelry. If you don’t regularly clean your silver pieces, the dirt residue can also scratch the surface as well.
 
When cleaning sterling silver jewelry, we recommend you use soft 100% cotton clothing or even a flannel cloth. For hard to reach areas, you can use a soft bristle brush. 
 
Chlorine and even vinegar can damage your silver jewelry, so don’t forget to take off your fine sterling silver jewelry when swimming.
