Treated Lyman corncob in a vibratory tumbler cleans and shines just fine and lasts for many many batches. When it's used up I use it for oil dry in the garage.

Never saw the need to bother myself with the extra expense of a wet cleaning system and waiting for the damn things to dry off.

I prefer peace. But if trouble must come, let it come in my time, so that my children may live in peace. ~~ Thomas Paine
