Lots of people have been asking me how to clean their jewelry or how I clean mine. There are two jars that I use every year to clean my jewelry and the jewelry that I make. They are both made by Connoisseurs - Silver and Precious.
You can get these products at Wal-Mart, Kohl's and Target, and they come with basket in each jar so you can dip the piece into the jar and get it back out. A word of caution: my mother dipped her silver and pearl necklace in the silver solution and the silver solution ripped the pearls of their luster. Use the precious solution for pearls and stones. You can also use the little brush that comes with the solution to hand clean the silver parts of a necklace without getting it onto the stone or pearl. These products are around $5-$8 each and are tried and trusted. How often? I believe once a year is enough. If you don't want to go this way, you can always purchase anti-tarnish strips in jewelry and some bead/jewelry craft stores!
