How do I clean old jewelry?

Carefully ! There might be loose stones held in by years worth of dirt & dust .

I would lay out a dish towel and use an old toothbrush dipped in warm water, then dab a little toothpaste ( not the gel kind ) on the brush and scrub the jewelry with it . Then rinse it off in a bowl of warm water, NOT IN THE SINK!!!!! If the jewelry is really dirty you might want to soak it in a bowl of warm water first. You can add some dish soap to it , but it will make it harder to hold because it will be slippery.

Hi Maretta. Here's a link that tells you how to clean the different stones and metals, like gold and silver:

Your local jeweler can do a beautiful job cleaning jewelry and usually complimentary while you wait!

Maretta; Tarnix works quite well. The dunk into a baking soda "bath" to readjust the PH

Soap and water and a tooth brush

I sell a lot of silver on Ebay. Jewelry, silverware, serving sets. Silver polish like Wrights and dips like TarnX tend to remove some of the metal. The foil method doesn't work that great and still leaves a grey film that still needs to be removed. I use white toothpaste (not gel) and a damp toothbrush. For large items I use a damp cloth. Also works on copper, brass, gold, porcelain, ceramics, sneakers, plastics, etc. For my sales I needed one product for cleaning everything.
