You think you have cleaning problems!!

Here are a couple of my winners.. Most of the bad coins come from the dry caves and not the moist outside ground..Moist ground is good..remember that! unless the ground is highly acidic,
Some of these are fused together.
I have been around and have done many things..Some of what you guys had said...I know the vinegar and salt works well and maybe too well sometimes..
Just wanted to share.. These are bronze coins by the way! A trip to my tumbler may be good since they don't need to worry about having scratches.. Nice to have the patina
Any suggestions would be great!

I never tried it but just read some interesting stuff on freezing them then tossing them in boiling water.
Thanks to PBK for the link.
