My first step is typically to throw a handful of wheats in a jar with mostly uncooked rice, water and a drop of Dawn. Then I shake it for about 20 minutes, dump and rinse. Takes most of the surface dirt off. This is not too harsh on the coin surface.
Looking for something that can clean the black crud from older wheat cents without wearing off the edges or removing the metal finish. The rice doesn't take the black crud off.
Anyone experimenting with other types of tumbler media?
I've used a large pencil eraser for years to remove some stubborn crud from individual coins... so now I am trying to tumble using the packages of children's tiny eraser's with water...
