Removing yellow discoloration on stainless steel cookware?
I don't know if we are describing the same "yellowish discoloration", but the problem I used to have, before switching to induction burner, was oil splash got baked-in the outer and inner walls of my SS cookware and leave yellowish stain. The first thing I try when it comes to cleaning is always vinegar. First I soak it in vinegar and the stain came off a little. Encouraged, I boiled it in a diluted vinegar solution, and it came out like new.
