recently someone posted for solutions to unstain their stainless steel cookware and fortunately i read the entire thread because right after it happened to me. just my luck. i made a black bean dessert in one of my brand new all clad pots and it seemed the black beans stained my pot. i was pretty bummed, especially after just one use. anyway, thanks to someone suggesting bon ami in the previous post i picked some up today at the grocery store (and for less than a dollar!) and now my pot looks brand new again. it seems too good to be true. so whoever that was that recommended bon ami, i am forever grateful. thanks for saving my pot. and for anyone else who might stumble into this situation, bon ami really does work.
