How to remove badly burnt on stains on Corningware pot from oven

post #1 of 18
Thread Starter 
My friend accidentally left a Corningware casserole dish(white) in the
oven at 400 degrees for six hours.

She was roasting vegetables and garlic in olive oil. Needless to say
the dish is a mess with burnt on stains that cannot be removed by
scrubbing etc. It was completely black after charred remains of the
vegetables were scraped off.

I have tried many things but alas this sentimental dish seems to be
dead. The black and brown stains seem to be painted on.

I can send you a pic. It's pretty ugly.

Can you help?

Thanks

Did you try 'Bartenders Friend' abrasive cleaner or a Brillo pad? OTOH,
Corningware isn't that expensive - buy another one.

Kosher salt and lots of scrubbing is one possibility.
I've used that to rescue enameled cast iron pieces.

Re: How to remove badly burnt on stains on Corningware pot from oven

Unfortunately the casserole dish is left over from her mother. It is a
SPICE OF LIFE Corningware casserole dish.

Can you get these in stores? I would like to buy her a new one if ...

Someone mentioned baking soda and vinegar. Have you tried this combo?

Thanks

Use spray on oven cleaner. It won't hurt the Corningware and it will take
off almost anything.

Try Ebay. I have found several pieces of Spice of Life there.

Oven cleaner (lye.) It work great on glass or stainless steel too;
don't use it on aluminum.

You have several options. Ammonia works well, the general household
method is to pour ammonia on the stains, then seal the thing in a
plastic bag for several days before removing, rinsing and washing. Oven
cleaner won't hurt corningware, I use one that doesn't require heat and
let it sit for whatever ammount of time stated by the manufacturer. Mr.
Clean or Scotch Magid Eraser sorks well for this sort of thing as well.

OK, now you've got me curious. What happens if you use it on aluminum?

If the stains are on the outside as well as the inside, pop it in a
big pot, cover it with water and lots of baking soda, and bring to a
boil, and then turn back down to medium heat. The resulting akali and
heat will loosen most of the burnt food, and once cooled, you can
scrub it off.

Strong alkalis disolve aluminum. I'm not sure what the reaction is, but
it gives off hydrogen gas.

If you have anodized cookware, using oven cleaner on it or washing it in
an electric dishwasher are about the only ways to ruin it (and are not
covered by the lifetime warranty.)

Lye will also etch the glaze off stoneware. I found that out by making
soap in a crockpot.

That's not necessarily correct. They are only making the French White
pattern nowadays, for one thing, so you can't even get the classic
Corningware shapes anymore, let alone the painted on cornflower blue design.
She said it was white, i don't if it had any other design on it, but if it's
any of their other patterns (there were many over the years, created to
match Corelle dinnerware patterns), then they are DEFINITELY irreplaceable.

Plus, the orginal poster says the dish is sentimental.

Anyway, as for getting the stains off: the baking soda idea inside is a
great one and it's gotten me out of quite a few messes. So try it. It will
take some of the mess off, at least. What you have to do is actually
chemically break the bonds between the crud and the dish. That crud is baked
on, it's not gonna just wipe right off. That Baking soda bath is a start.

Whatever is left, use a powdered cleanser called "BAR KEEPER'S FRIEND".
WalMart has it, many supermarkets have it, too. Wet the dish. Sprinkle on
a liberal dose of cleanser, let it sit a minute or so and then scrub with a
sponge. That should get the brown stains up no problem.

I use Barkeeeper's Friend on Corningware all the time....my Corningware
pieces are about 40 years old, give or take. And although I consider myself
a Corningware and Pyrex collector, I actually use the stuff, all the time,
every day. So keeping them sparkling clean is important to me.

The Corning outlets also sell a soft cleanser that works nicely, but it's no
better than BKF, which is easier to get your hands on and not as expensive.

Actually, that's a great product, except that it's called "Barkeeper's
Friend".

And you can't just go get another anymore. They don't make it really
anymore, except for the French White. It's not what it used to be.

Anyone who has old Corningware, hang onto it!!!!

You can find odd pieces on Ebay or at thrift stores, but it's getting harder
and harder to find.

Which, IIRC, is explosive! So there might be a mushroom cloud after all.

I'm not in the tax bracket which can afford cookware with warranties.

Fascinating! My day is now not in vain since I have learned several
interesting new pieces of information.

Thanks.
