Taking a tumble into brass cleaners

[lowb]

Might clean the brass fine, do you want that fouling and other chemicals from shooting on your clothes though?

Just occurs to me might not be great for your skin?

If you don't let your cases get real dirty then you don't need a tumbler . Washing them in CLR and warm water will get all the patina and grime off . Then rinse twice in quite hot water and dry in Sun or hair dryer or very low oven with the door left open . No heat guns either.

Hmmm. It all washes away that easily you reckon?

Not saying you're wrong, just being cautious. You know how these kind of things in tiny doses turn out to be bad for you 20 years later...
