Valuable PMC TIP!

I have been to the Milwaukee Bead and Button show and no one there that did PMC had heard or thought of using rubber polishing bits. I discovered this through trial and error. I purchased them on ebay really cheap. These bits almost eliminate the need for the polishing cloths and pickle. The rubber polishing bits get out fire scale,scuff and small scratches. I found they even work on my other precious metal items. It can leave behind a small amount of greasy residue but I just use a little jewelry cleaner and VOILA! CLEAN, fast,harmless and easy. No more scary expensive HARMFUL pickle yes there is a nontoxic pickle but it's pricey and unnecessary. I would suggest purchasing all different sizes and shapes and the do dissipate over time.
