cayugad, i just tried it on my pots and pans .unreal, it took the dull stuff right off bottom of pans. copper is back bright. i then used bon-ami on next pot, nothing. bar keepers friend does shine brass.i had broilers that i could never get clean .i put that bar keepers friend on it, left it sit for 5 minutes and all crud came off. the stuff is unreal. but never get it near bluing or painted surface.i think it has acid in it.
