I am having good luck removing tarnish on sterling jewelry with corn
cob with cerium oxide, dry. Most of the pieces have stones or
pearls. I also have plain chains which I have not tried tumbling
yet. It is just tarnish from being on display, no dirt. (I have been
putting off this chore for YEARS, so have so much to do, hand
polishing is not an option. I also have carpal tunnel syndrome, and
polishing does a number on my wrists).
I also have Rio Red Buff and Green Buff. Can someone tell me how
these 3 compounds differ? Is there a difference in how aggressive
Maybe I could batch the pieces: like use the most aggressive
polisher on plain silver, the least on pearls, opals, etc.
When I’ve used red buff before, along time ago, it colored the
pearls. It did not come off. The cerium oxide doesn’t seem to do
that, at least not for the length of time I’ve been tumbling them
(half an hour to a whole hour). In a one hour tumble, I noticed that
it took the gloss off amber, so I won’t tumble the amber as long.
But knowing which compound to use for what would help. Thanks!
