Great for Pewter!
We used Met All to clean 25 year old pewter flatware (that had really never been polished). Had tried several other products, with lackluster results. Very pleased with this product..seems to be the only thing that works. The pewter is hard to clean because it has been neglected for so long.... but we're working through our collection...one piece a day. Tip: have plenty of clean DRY cleaning cloths.
