Cast iron question

Does anyone have any ideas how to salvage a cast iron D.O. that has been cleaned with oven cleaner? :blink:

Besides using it as a planter.

    If you place it in a self cleaning oven and pt the oven on clean it will bake off anything that is on the outside, including any blackening or seasoning that has occurred. The pot should come out looking like the day it was cast. It will be very prone to rust so re-season it immediately.

    Also do this only on a day that it is warm enough to open widows. The burning off of the blackened surface of the pan can cause quite a bit of smoke.

    A good cleaning with strong Dawn letting it soak. Afterwards take the sand paper or commercial abrassive pad and rub to new metel. Reseason. The pic of the DO in oven is first rub reseasoning it. I have restored a DO and a skillet from flea market that way. My only concern is the chemicals used in the oven cleaner penetrating the steel. Mine had not been "Easy Off" that I know of Not sure if the Dawn would cut it or not. If your sanding is proper you should remove residue. NEW08044.jpg NEW08004-2.jpg NEW08070.jpg

    What about a rusted skillet? How does one re-season / remove the rust and start anew, or is it too late? Thanks...

    Marge that was how mine were. To reseason after cleaning/sanding rub with shortning (not oil) the intire surface lightly and bake in oven 300 degrees for 2 hrs. I wipe the surface after 1 hr. Allow to cool and repeat once more.

    Michael I'm not sure that the oven cleaner is a problem, as far as I know it is just lie. I have collected Griswold cast Iron for years and it is the best way to get the cooked on grease and food off. I have done it many times and used pans for cooking after reseasoning them.
    The self clean in an oven can crack them I have been told by other collectors. I think if you give it a good scrubing in dish soap rinse in hot water, reseason.
    Hope this helps.

  • Had some old cast iron skilets that had several decades of black build up on the non cooking surfaces. Fired up the LP fish cooker one night to do some Blackened Redfish. As the Skilet was getting white hot I noticed the build up coming off the sides. Skilet looked like a brand new one when I was finished. Reseasoned then and were better than ever. Even cooked better after the build up was removed. Pulled out the dutch oven and did them the same way.
  • Could you use the Egg to clean a DO
  • Michael B,[p]Why won't doing a super-cook with Crisco all over it do the job? Re-curing, in other words.
  • Michael B,[p]Place it upside down in the oven and turn it to the cleaning cycle. Let it run through the entire cleaning time then wipe out and reseason with oil.

    Michael B,[p]I use to work at a machine shop and we would clean old cast iron stuff...[p]And I still do it with my egg...Just dump some lump in the egg...bring up the temp to over 600 deg...700 works very well..and put the cast iron pot in and let it cook away..[p]Now if you have an old cast iron pot that is really grungy you can clean it to look like new...Open the vents on the egg all the and bottom..[p]and drop the iron pot right on the coals...leave the egg running full steam and after 30 mins you pot will be glowing red hot and "everything" will be burnt you will need to bring the temp down on the egg till you get to around 300 deg and then you need to season the pot or it will rust in seconds...[p]Oil it all over and put back into the egg and shut down all the vents....and when the egg is cool you pan is done![p]

    I would suggest filling it with Coke, not the diet stuff, real coke. Let it sit for a couple of days. Then clean it really well baking soda and metal scouring pad. Then coat with oil bake in a low temp oven. That should do it.

    Thanks icemncmth,
    I hadn't thought about putting it down in the coals. 1200* should do it.

    Rust Haven

    My Cordless Drill and the Wire brush bit, gloves and googles

    About one hour later rust is mostly gone

    Bacon grease, lard, crisco, oil in that order...

    450 dome till pot is black. Repeat grease as needed

    Viola ready to cook.

    To burn off that oven cleaner this is probably the best way.

    However without a lid it's not really worth it.
  • Wipe it with CRISCO, turn it upside down in a 350 oven for an hour. Turn the heat off and leave it in until the oven is cold..repeat

    If it was just rust, it wouldn't be any problem. But I would kinda worry about the chemical resisdue left over from the oven cleaner and a food crossover. Personally, I would check one of the big dutch oven sites and ask them.
