I am a newbie to this site but wanted to share with you what I have discovered about cleaning the clad coins I have found.
I read and tried numerous ways that others have posted but none seem to work as well for me as my method. I built a tumbler from parts I had laying around so not much expense there. I took 10 shotgun shells and took the steel shot out of them and put them in my tumbler can and added WD-40 to cover all the shot and coins. I than tumbled them and periodically checked the progress until I was satisfied they were at the point of cleanliness that I wanted. It did not destroy the coin and got all of most all the crude and discoloration off the coins. So far it is the best method I have found, hope it helps some of you out there with yours.
