Here is a tip for removing patina and polishing the inside of a ring shank from @cbgems - “I use @riogrande Brass Brush Item #338335 in my Foredom flex shaft to easily access the inside of any ring shank and give it a quick polish. Just be sure to have a good grip on your ring!” I love this idea because the brass brush won’t remove more material the way a sander will so if all you want to do is remove patina and give a shine this is a great tool for your toolbox! Thank you so much for sharing!! #metalsmithsociety #jewelrypolishing #tipoftheday
