Discoloration on Stainless Steel Pot

Hi,

On behalf of my mom...she was just wondering about some discoloration. She had a stainless-steel quart pot (Ikea, I think) that she uses mostly for boiling vegetables. It's nine months old. The inside of the pot has gotten discolored, (the last thing she boiled in it was carrots) and was just wondering if the discoloration was from natural aging or something else i.e. the cookware itself. Any insight appreciated!

  1. Discoloration is normal in stainless steel. Often you get some clouding on the bottom or even some rainbow effect, but there's nothing that you need to worry about. I'm sure you're going to get many comments instructing you to use bar keeper's friend to polish the inside of the pot but it's highly, highly unnecessary. Just keep using the thing and she'll be fine.

    1. Basically what you have is a mineral haze at that point. It becomes a mineral deposit (gross form) if left alone.

      BKF contains Oxalic acid (very weak acid) and a detergent. IMHO BKF should be taken off the kitchen product shelves moved into sporting goods department as elbow exercise powders.

      FYI true elbow grease is taking those Cortisone shots in the elbow. OUCH! Almost effortless treatments involve deliming or descaling solutions to your pot, of course.

      1. When discolourations happen in my All-Clad ss pots, I either boil with vinegar or scour with BKF (Bar Keepers Friend).

          Personally, I think SoftScrub does every bit as good a job, it's more available (any grocery store) and I'm guessing it's cheaper as well. The only thing is that it doesn't rinse off easily so I wash the pans again with detergent after I've scoured them. But I've got 30 year old stainless that's still beautiful from that care.

            BKF is cheap if you buy from Lowe's....

              rainey, I've only found two products that adequately clean my kitchen sink (ceramic or porcelain; I can't remember, though I chose it). One is a Magic Eraser, but the SoftScrub's the best, the quickest and the easiest. Makes that baby look brand new. So I had thought about using it on my SS pans that have rainbow stains inside, but the SoftScrub bottle says it has bleach, and I wasn't sure I was supposed to use that in a cooking utensil. It's okay, though?

            Told you so. :-)

            Just keep using it the pot, there are no problems with it or it's performance. I've never had a desire to polish the inside of a pot that I'm about to cook with again. I consider it a waste of time to polish the inside of my pots and pans and I don't desire or require a Food Network glossy shine on my cooking surface.

              I wonder how much of their stuff ends up in the dumpster?

              Show Director::: CUT! Can someone dump that stuff in a clean pan!!! ;-)

            2. HaagenDazs is 100% correct!
