Does anyone have a recipe to use in rock tumbler for cleaning clad coins?
I have read several orver the years and herad one at a club meeting one time. I'm just wondering what others may be using. here is what I'm currently using. Aqurrium rock, about half of the tumbler full, Bar Keepers Friend, about 2 Tbl spns, and dry coffee grounds about 2 tbl spns. It seems to work well. I'm just curious what others might use. Thanks

I will use it to clean some old clad coins and then describe you the result.

Why are you cleaning them? You should NEVER clean a coin. It will greatly decrease any numismatic value the coin has. If you don't have a valuable coin and just want it to look nice, have at it.

I use aquarium gravel, a little water, and 2 drops of Dawn dishwashing liquid. It does a great job and then they're ready for the coinstar machine!

I use a tumbler all the time to clean clad coin.. simply, use beach sand and 2 tablespoons of dish detergent. Tumble for 6 hours and wash off coins should be clean . Andy

It doesn't shine them up but I put them in the tumbler with crushed walnut shells. Simple to do and does a very nice job taking all the dirt and grime off. Ready for the coin sorter. It doesn't beat the crap outta them like the gravel does.

This is what I do...just the cost of a squirt of dish detergent. The beach sand is free. Once the coins are clean they go right into the machine at the bank so no need to roll them.

I deal in reality
Have used the rolling type tumbler with several types of cleaning compounds in the past. I have just ordered a vibrating "tumbler" . Keep an eye out for my cleaning post results with actual formulas, and before and after pictures of the coins and tokens.

any copper coin such as wheats indians and tokens, tumble them for about 20 minutes then dry them off and put a coat of cooking oil on them over night they look fantastic.
silver I just wash with soap and H2O unless there is corrosion in it then I use electorlysis for about 10 min then tumble for a brief spell.
nickels If in good shape I do the exact same as pennys but if I have a tough one then soak it in CLR and then hit it with fine steel whool and it will look like it came out of circulation.
alum tokens I soak them in CLR to take rust off it works great.
Clad just pull out ant really bad ones wash them is soapy water then take them to the bank, I have had no problems.
Most coins found in the ground are in poor condition anyway, they would most likly be graded as corroded so make them look good and enjoy them.
