Cleaning My Zincolns.
I had some zincolns that were really eroded that the coin-star machine wouldn't accept so I tumbled them in a rock polisher for about 5 hours, you could not even tell that these were penny's before i cleaned them. I used about 4 tablespoons of salt dish soap detergent and some fish tank gravel. I think the salt is what turned them black i think i used to much. They still look pretty bad... I need to put them in longer....
Put them back in overnight and this afternoon this time with only dish soap gravel and water no salt. They look much better the white things on them are holes their not dirty anymore http://www.bigboyshobbies.net/
