What is the best thing to use to clean coins someone said a tumbler is that right or is there something else out there thanks.

Depends on the coins rule is to never clean valuable coins:

For tough and very dirty coins I use backing soda/powder to remove the dirt and the easiest to remove layers. (here the oxides build up layers very often)
then I use "Yes Power Spray" and spray it on the coin this does a good work, let it sit for 30 min then wipe it off and put more on if needed.

Then if I want them to shine I use cerium oxide with saw dust. (dry)

For Bronze use Vinegar and salt solution. (got that one from a amateur archaeologist)

PS. This is for none valuable coins, modern.

I use electrolysis. My coins come out looking mint new. That's after being unrecognizable when i first uncover them.And I'm speaking of clad. silver doesnt need much cleaning just wiped off. at least here in texas soil.

I bought a Vibratory case cleaner from the gun shop yesterday. It is designed to clean the bullet casings for a gun. It has round corn granules in it which are all placed in the main cleaner housing with the coins. It vibrates rapidly to clean. It won't damage the coins, but I wouldn't put potentially valuable coins in it for the simple reason, that I think that they will comer out with a highly polished finish, which would destroy a coins value.

Depends which coins. If it is ones to turn back in (zinc and clad), just shake them around in a sand scoop to get the loose dirt off and run them through a coin machine. No muss, no fuss. No rejects either.
