Big mistake...

[Old Katz]

When I tumbled the clad I threw in the medallion that reads, "coach." Big mistake.!~
After 11 hours the clad came out clean but PINK. I looked all through the clad thinking
I must have accidentally dropped in a penny. No such luck. I'm sure it was "the coach."
Now I'm tumbling it all over again with ammonia and vinegar hoping to get read of that
bronze/pink color.

Hey Katz, if i"m workintg with plain old spending money (nothing that's a keeper), here's my method. Go to a pet supply store and buy a bottle of grit for small birds. Put some in the tumbler with some water, a dash of dawn dish soap and don't tumble it for more that an hour or hour and a half. Comes out pretty good and plenty clean enough for the bank. If you tumble it for much more than that it will come out showing excessive wear. I don't have the patience or time to let it go for 11 hours. Seems to work pretty good for me.

Grit for small birds? Hummmm.
I may give that a try on the next batch of clad.

Go to the pet shop and get a bag of aquarium gravel without color added (clear). Put in about 30 coins (not pennies) add a very small amount of liquid soap
a small amount of lemon juice and or vinegar. Roll for two hours and its a thing of beauty. (like new).

Lemon juice? Now that sounds like it could work.

Lemon juice works awesome on copper get the green tarnish out.does anybody uses pea gravel?

 

[Old Katz]

I bought a 5lb bag of aquarium pea gravel for $4.95 fro Wal-mart
and still have half a bag. It works just fine.. I'll have to try the lemon juice and see how it works.

If you use lemon juice i usually put some in a small container let coin soak if its a old coin dont leave it to long cause it will eat off the dates especially copper.I have'nt tried it in the tumbler yet.
