If you're not interested in something exotic, then Zam is the
ideal polish for silver, IMO and others. Great stuff....
John, We use a looot of ZAM in our studio primarily because it is a
teaching studio and my students can mostly only afford silver. We
love ZAM. It not only does a super job on silver but it will also
polish turquoise, malachite, bone, rhodocrosite, black/red coral,
and other natural materials. In fact, when cutting, if I have a stone
that just doesn’t seem to want to polish on the oxides, I always try
ZAM. Most of the time it works wonders.
