I have several character cake pans that are discolored from the dishwasher. I do not use most of them and was going to try and sell them.

Does anyone know how to make them shiny again? (if possible)

I don't think they can be made shiny again like when they were new. I have some that I"ve put through the dishwasher and they now have that dull look. Some people won't mind if they are dull.

Two products: Bar Keepers Friend and Cameo. Both are stainless steel cleaners. I use Cameo all the time and it can take those nasty brown cookie sheets and turn them into shiny new metal again. (Lots of elbow grease, but it can be done!)
