In my collection of new dirt eggs I have found some unique junk along with alot of clad.Some of the junk I would like to clean and talk about, the clad I would like to put it in a bank account for future upgrades. The problem is the banks have stated they do not accept dirty money. Is there an economical way to clean the stuff worth nothing of face value? I have been looking at the tumblers and also the sound wave cleaning machines, but I can't seem to find any good research on these. I see you have to buy additives for either so which would be more economical? I have tried to scrubb with dawn and a brush but the bank still says no. What ever cleaner I get I would like to be able to use it with some of the stuff that would be woth something. I have heard that some cleaning of certian items drops the value, I am okay with that I plan to pass all my finds and stories down to the grand chaps. Any Ideas?? Thanks for all the help
