Here are a few things you can do to keep your silver shining, and tarnish free:

1. Keep silver away from sulfurous material, sulfur is silver’s main corrosive agent.
   What’s corrosive?
   Ammonia (Think glass cleaner.)
   Nair (Take the jewelry off before you use it.)
   
   OK, you forgot to take the rings off… what now?
   I am going to tell you a secret…
   Use vinegar to clean the discoloration.
   VINEGAR WILL NOT CLEAN SILVER, BUT IT IS OPPOSITE ON THE PH SCALE AND WILL NEGATE THE CAUSE – THEN – Use the polishing cloth to polish your silver.
2. Also, keeping your silver in an airtight plastic bag (like a Ziploc bag) will also help; this will keep the sulfur and other corrosive agents in the air from coming in contact with your silver. Your jewelry box may be a mass of plastic bags… but the jewelry will look good!
3. Know that silver can tarnish rapidly when exposed to the sun and salt air. So if you wear your jewelry to the beach or on a boat, it will tarnish. That's when I use a polishing cloth to give it a quick wipe before I put it away. I like the Haggerty products and have it available if you need it, but you can usually buy it in many places.
   

Your sterling silver jewelry should be worn and enjoyed… and your body oils also help prevent tarnishing.
