Mix metals in the tumbler

If I run nickel, brass or copper jewelry in the same tumblers I’m
running my silver jewelry in will it contaminate the media?

Thanks for any advice,
Sam

The short answer is yes but the contamination will be negligible if
you use a different set of media for each metal. Then, a quick run
with soap and the new type of media will get rid of any residues. !0
minutes will be long enough. Then rinse and charge as normal.
