Here's what I used:
Glass baking pan
All you need to do is line the baking pan with the aluminum foil. (I used the kind that's already cut into sheets and it worked great) Place jewelry on top of the foil. Sprinkle with baking soda. Pour boiling water to cover the jewelry in the pan and let it set for a few minutes. It will bubble and smell....the chemical reaction causes a sulfur smell. It's not too strong though, and it goes away quickly.
Fish the jewelry out with some tongs and rinse under cool water. I wiped it off with a soft cloth to remove any residue and it was good as new!
I honestly couldn't believe how well this worked! It also words perfectly for silver serving forks, spoons and such! It's fast, cheap, easy and chemical free....sounds like it's right up my alley!
