Jared and I received a set of beautiful stainless pots and pans a year or so ago for Christmas from his parents. We were living with a roommate at the time so until recently they have been packed up in a box. I love cooking with them and they are so nice to look at. When I had trouble getting them clean and shiny I asked my Grandmother about it and she went to the cupboard and pulled out a gold can of Bar Keepers Friend.
I must have been living under a rock for my 22 years since I had never heard of it. Now I can't live without it. It's been keeping my Grandma's stainless steels pots and pans shiny and beautiful for about 40 years now and has been a staple in kitchen cupboards since 1882. If you don't have a can under your sink right now you ought to go out and grab one as it cleans just about anything (and I do mean CLEAN).
