Clean Jewelry with Denture Cleaning Tabs

A jeweler once years ago told me about using denture tablets to clean my jewelry. I have been using them for 40 years now and my jewelry is still beautiful.
I place one denture tab in a vibrating cup, put in enough water to cover my jewelry, add the jewelry and turn it on. I let it run for 30 minutes, then rinse everythng really good and let it dry. I do this about once every 1-2 months depending on how dirty my jewelry has gotten.

I've always used rubbing alcohol and a toothbrush. Brush always up from the base of any of the little wires that hold the stones in.

I googled jewelry denture cleaner. It sounds like it may not be a good idea. Go to this link, http://en.allexperts.com/q/Jewelry-Gems-Minerals-689/Cleaning.htm
This guy sounds like he did his research. He says the chemicals found in denture cleaner may weaken the jewelry. I hope this helps you. I saw on a different site that vinegar may be a possible option for cleaning jewelry.
