Hello,

I'm a fairly new rock hound, and I was wondering if someone could tell me the best way to clean peridot? I have several small pieces I picked up, that would be really pretty if they didn't have brownish stains on them. I've used super iron out on my aquas, smokies, and amethyst, but I want sure if it would hurt the peridot. Anyone tried it before? Or should I try vinegar first?

Hi sparklerocks, welcome to the forums!

I would guess vinegar and then iron out if necessary. As far as I know olivine/peridot does not have adverse reaction. Let us know how it works!

SIO won't hurt them... Been there done that, if nothing else - to take off the iron stain - we've found wet sandpaper to work wonders!!! Holy hell fire! You might get the same 'ol rusty crap (pocket mud... sure sure,...off) but wet/dry sandpaper (wet) works wonders for taking off layers of rust.

(If it has natural facets and/er can be 'polished' er cleaned with such, if not... welp... )

Thank you! I'll let you know how it goes!
