IF YOU PURCHASE STERLING SILVER JEWELRY, IN ORDER TO SLOW THE PROCESS OF TARNISHING, KEEP YOUR PIECES IN SMALL AIRTIGHT PLASTIC BAGS.  yOU CAN FIND SMALL 2" X 2" OR 2" X 3" AT YOUR LOCAL ART SUPPLY STORES. 

WHEN CLEANING YOUR JEWELRY, IF IT HAS GEMSTONES, PEARLS OR OTHER ORGANIC MATERIALS, YOU WANT TO MAKE SURE THAT YOU DO NOT USE TOO HARSH OF A CLEANER OR YOU CAN EASILY RUIN THE PIECE. READ JEWELRY CLEANER JARS CAREFULLY.  THINGS SUCH AS PEARLS AND OTHER SOFTER GEMSTONES USE A GENTLE CLEANER.  HARDER GEMSTONES AND BEADS CAN USE A MORE STRINGENT CLEANER.  IF YOU ARE NOT SURE WHAT TO USE, ASK YOUR LOCAL JEWELER.  AS A LAST RESORT, YOU CAN ALWAYS USE SILVER OR GOLD CLEANING CLOTHS THAT ARE A VERY SMALL COST AND WORK QUITE WELL WHEN USED PROPERLY.
