So I must be getting old I finally left a pan on the stove. I was boiling some salted water. By the time I came back the salt was stuck to the bottom and sides of the pot. When I went to wash it it was blackish but looks like the salt may have taken the polish off the stainless. It was a top of the line cusinart. It sort of looks like this http://chowhound.chow.com/topics/970485
Is it just the shine thats gone? Could if of gone into a lower layer? It dosnt look like that but.. I might take it in to store but a lot of sales people don't know much about anything these days and will probably just try and sell me a new one.
