Whoops! Rancid Cast-Iron Seasoning

Silly me stuck the lid on my cast iron dutch oven, and in that lovely air-tight environment, the seasoning developed a lovely rancid scent. Other than completely stripping the seasoning out of it, how can I restore it? Or just I just throw my roast in it and not worry about it?

If your oven has a self-cleaning cycle on it, put the cast iron inside the oven and run the self clean. That will remove all the old seasoning and then you can reseason.

You can also wash it by hand with a mild dish detergent, wipe it dry, and then oil it down with some grape seed oil, then roast away.

I'd definitely get some steel wool and scrub the old seasoning off in hot water with a little mild detergent. Then re-season it. I store mine upside down on a rack under my cupboard in the kitchen, to let air circulate at all times.

I don't think that's necessary, but if you like giving yourself extra work and have nothing better to do, then by all means go ahead. Re-seasoning is only really needed if you have rust issues, doesn't sound like that's the case.

I would do as simon said. However, I use plain veggie oil. I wash it and then dry it on the stove when it starts to smoke i oil it. It won't change to flavor of whatever you are cooking if you clean it up,it should be perfect again:)

I'd recomend a good scrub in hot water and soap, because rancid fat is spoiled fat, and I'd be concerned about making myself or anyone else ill from it. Not really any more work than what one would do after using it. Steel wool removes seasoning very easily. Just be sure to wear rubber gloves.

Thanks for the suggestions! I tried washing with soap and water, but the smell really didn't fade much. Being short on steel wool (and needing to get the roast in the oven), I invoked the ultimate power: I called my mom. Her suggestion? Fill the pot with heavily salted water, bring to a boil, dump and rinse well. Worked like a charm.

Salt is a disinfectant. Great idea MOM!

Haha! Exactly. I was going to recommend boiling with some salted water and then wipe with oil and reheat.
I also crisco. It doesn't get sticky.
Heat well and it won't get rancid. Translated-heat the holy crap out of it.

i just saw this and was going to suggest baking soda.

@carol - "crisco" and "sticky" in the same post? You're just testing me, aren't you?

Haha, It doesn't though, if you heat the hell out of it.

A duel, sir?

I remember the time my seasoning on a couple of French crepe pans went horribly wrong, leaving a layer of hard bubbles on the bottom of one of the pans. I put a sanding bit on my drill and completely wore down the seasoning, then re-seasoned the pan correctly. Sounds extreme but it worked.

carolrsfMISSESTEXAS: I also crisco my iron skillet-never fails

SALT! A great idea! I have a couple of cast iron pans in need of reseasoning. Great idea.
