My friend did exactly as you said and look!!! Thank you!!That button should clean up nice. I would soak it in 50/50 lemon juice and water, keeping an eye on it and hitting it with a toothbrush every two or three minutes until you get it the way you want it. Then use a baking soda and water rinse to neutralize any remaining citric acid that may be on it. Many naval buttons had a strong gold gilt to protect them from the salt atmosphere aboard ships.

You only want to do this with buttons that still have a lot of gold gilt under the crud. The citric acid will attack brass.A really good tip Steve, something to remember. Lots of sound advice on T-Net.
