This stuff is like magic. I used it on a stainless steel revolver with a dull, lifeless finish. An hour's easy work and it was gleaming and mirror-like. Encouraged by this I tried it on a set of 40 year old stainless steel flatware that had long lost its shine and had resisted any efforts to restore it with other polishes. Once again the Mothers did the trick (and without much rubbing either.) The flatware doesn't look quite new, but the Mothers definitely removed at least 30 years of staining. I am seriously impressed.
