Thread: discoloring of stainless steel pots from overheating?

    Default discoloring of stainless steel pots from overheating?

    is anybody familiar with the discoloring of stainless steel pots from
    overheating?

    I saw a manual for one that said "damage from overheating is instantly
    recognizable as the stainless steel surface may change color producing
    a golden/brown/blue appearance. This is not reversable and cannot be
    cleaned off. However it will not affect performance in any way".

    Does this sound familiar to people?

    Yup, but usually with thinner, less expensive pans. I have not seen it
    since I have a grown-up's set of pots and pans.

    It does. And I find that with some elbow grease and a plastic scrubby
    and soap, it can be removed.

    You have to *really* work at it.<g> Like leave the 'water'

    Yep. Scrub the inside of the pot with Bon Ami or Barkeepers Friend.

    Use oven cleaner on the outside if there's any burned-on grease, then
    polish gently with chrome polish. You won't get it looking new again,
    but you can get it presentable.

    Or just don't worry about it.

    No, it will occur in high-end SS cookware, also. You jes hafta get the
    good stuff up to "glowing" temps, as I have since proven.

    OTOH, I spent good money on my cookware to provide good and reliable
    service, not to impress guests and tourists.

    Hmmm...I switched to ceramic-top electric when we moved in here and
    that is about the time I got my good cookware. The electric stove may
    have contributed more to my not having it occur lately than the pots
    themselves.

    Thanks for the ponder.

    Yes. That's one of the reasons why I didn't get the mirror finish
    when I spent what I consider "real money" on cookware.

    I have. It doesn't affect the cooking qualities, though.

    Yeah, so I have been told. I used to see it all the time, but never do
    now. I assure you, it isn't as if I get *less* forgetful as I age.

    Yes.

    I have had an ex-gf 'blue' a bunch of my pans, and I burnt my 8qt
    stock pot on someone's smoothtop range (gawd how i hate those).


    Interestingly, I've noticed that in time and use the color fades away
    and you don't see it anymore. Also, the pans still work the same,
    but I bet they've been weakened.

    Any idea what the mirror finish is made of?

    What the discoloring is.

    Are there any leakage or health issues with using it after it has
    discolored?

    If it can be removed then why does it bother you?

    What makes make stainless steel pots without the mirror finish?

    I do want it to be metal inside.

    Looking at this pot,

    http://www.lecreuset.co.uk/Product-R...-and-Lid-20cm/

    the upper side and bottom side of the lid of the pot is very mirror
    like. I've seen it.. But i'm not sure whether you'd say that of the
    inside.

    Has anybody seen discoloring on pots that don't have a mirror like
    finish? Were people that have seen discoloring on their pots, able to
    see their face on the surface where the discoloring was?
    (that would help determine if pots without the mirror finish
    wouldn't/couldn't ever get discolored from I suppose, the accident of
    overheating dry).

    Lots of them, high end and low end. I have Teflon pans from Macy's
    that are a discolored outside mirror finish and it's ugly. I'll be
    glad when I throw them away.

    I hadn't used a stainless steel interior pan since I moved out of my
    mother's house (she had Revereware which I hated and turned me off to
    considering any stainless steel cookware until recently). Then I
    bought two All Clad saucepans and one skillet
    ;, which it turns out I love.

    My All Clad has mirror finished lids on the outside surface. I was
    uncertain about the saucepan/skillet themselves having a mirror
    finish, mainly because I don't have the shelf space to store them so
    they're out on a pot rack.

    Yes

    I have had excellent results removing minor heat discoloration
    (bluish) from a couple of medium size stainless steel pots, using
    Cameo Aluminum & Stainless Steel Cleaner. This is the only product
    that has worked for me. One pot had a satin finish interior. The
    other had a polished interior. The cleaner is relatively non-
    abrasive and is not gritty enough to scratch a polished finish.

    I use this product on all my stainless steel, inside and out, as well
    as on my stainless steel sinks. Also works on chrome.

    http://www.greatcleaners.com/Product...ID-33200-06800

    I used to find the product in virtually every supermarket; however,
    lately it has been increasingly difficult to find, although it is
    readily available online at reasonable prices.

    This isn't anything that is magically related to shiny finishes or
    stainless steel. Heat most steels to around 580F and they'll turn blue
    (don't go quite so high you get yellow, go higher you get gray). It's
    oxidation, it's normal, and it's telling you things about the state of
    heat-treatment--it's badness on knives, chisels, drill bits and the like
    because it means that you've softened the edge, but on pots and pans it
    shouldn't make any difference at all.

    You'll also see it on motorcycle exhausts.

    There's some stuff called "Blue Job" that you can get at some motorcycle
    shops that is supposed to take it off without scratching but it still
    takes some scrubbing.

    It can also be removed electrochemically but I don't know of a tested
    process that can be done with stuff commonly found in the home or
    readily available from Home Despot and Rat Shack.

    The discoloration from over heating can easily be reversed by
    freezing... of course the temperature would need to be as many degrees
    below zero as the pot was heated above zero.

    Yes, but m/c exhausts are chromed, not polished.

    Using the right abrasive scrubby, you can scrub all day on chrome and
    it won't scratch. Polished SS will. I used to polish all the burnt
    on oil and boot rubber off my HD pipes by using Simple Green and 00000
    grade steel wool on med hot pipe. I don't recall, exactly, if it removed the
    bluing, but I think it did.

    That Blue Job stuff may work if one uses a non-scratching scrubby.
    Have you tried? As for general cleaning of polished SS, jes spray
    with oven cleaner and rinse off.
