It's stainless steel pan. After using it for steaming chicken, fish, the pan has got brown/stains (pls see picture). Cannot be removed with baking soda and stains are smooth. Should I continue to use? Am concerned about chemicals coming out from stains when pan is heated (even though used for steaming only). Pls advise. Thanks.
If you are in the USA, Bar Keepers Friend is a useful product that we've had success using to clean stainless steel kitchen bowls, pots, etc. If you are not in the USA, find a cleaner with oxalic acid as the active ingredient.
