[QUOTE="Aslanmia, post: 335557, member: 11753"]I had them soaking in oil for a few weeks, then I let the excess oil drip off them before I placed them in a colinder that I flattened out and lined with coffee filters (the closest thing I had to cheesecloth). Then I just placed the colinder in a boiling pot of water for a few minutes, rinsed them with tap water and distilled water, then patted them dry. Like I said, I only had them in the boiling water for a few minutes and I didn't add much baking soda, but I did put in one old Indian Head penny that was pretty much all green. While in the oil, it went back to a dark brown colour, but after being boiled and dried it quickly went back to mostly green again. :P One thing that DID happen was a lot of dirt came off the coins and as you know that's not always a good thing, especially with pennies. In same cases it worked nicely... in others you can clearly see bright copper spots where the dirt used to be... not attractive![/QUOTE]
