Introduction

Cast iron pans and skillets are a joy to cook with, but maintaining them can be demanding and a failure to do so can lead to rusted and ruined cookware. Fortunately, cast iron is resilient and removing that rust is actually quite easy. The main trick to restoring any piece of cast iron cookware is actually properly re-seasoning it. Though there are many methods to accomplish this, our guide aims to present the process with the best blend of cost effectiveness and safety.

  1. Identify rust spots on the cast iron pan or skillet
    • Identify rust spots on the cast iron pan or skillet

    • If there is noticeable rust, continue to step 2. If there is not, and the pan or skillet merely needs to be re-seasoned, then skip to step 4.

    Sometimes rust isn’t the crucial problem, but years of accumulated gunk. I picked up a pan at a yard sale that had a thick coating of cooked-on oil, etc., everywhere but the cooking surface. The first thing I did was put the pan in the oven and turned on the self-clean cycle, which raised the temperature high enough to oxidize all that stuff off. It stunk to high heaven, but since it was summer I just opened all the windows and went outside and read for a few hours.

    A friend in the restaurant biz later told me they deal with that problem all the time, and just put the pan on a high-temp gas burner and let it get absurdly hot (not quite red hot), with the ventilation on high. That might be preferable to using an oven’s cleaning cycle. Dunno.

    After that, you’ve probably got a rust-free pan, and if so you can jump to Step 4.

  2. Prepare the vinegar soak.
    • Prepare the vinegar soak.

    • The tub or basin used should be large enough to completely submerge the desired piece of cookware.

    • The soak should be roughly a 1:1 ratio between white vinegar and water.

    • The ratio does not need to be exact; close enough is good enough.

    • Let the pan or skillet soak for roughly 30 minutes or until the rust begins to flake off.

    • An easy way to check if the pan is ready is to scratch lightly at the rust with a fingernail. If it flakes off immediately, remove the pan from the soak.

    • Thoroughly rinse and refill the tub with water. A kitchen sink can be used for this step instead.

    • Thoroughly rinse the pan or skillet, then scrub it with steel wool and dish soap.

    • Continue to scrub until there is no remaining rust.

    • It is important to note that the seasoning has now been completely removed along with the rust. This is not a problem as re-seasoning will be covered in the next step.

    • Dry the pan or skillet thoroughly. No moisture can remain when continuing onto the next step.

    • Optionally, the pan can be placed into an oven set to warm to dry it both quickly and thoroughly.

    • Coat the pan or skillet with vegetable oil.

    • Spread the oil evenly across the surface of the pan.

    • The coating should be kept relatively thin, so do not be afraid to dab up excess oil with a paper towel.

    • Spread aluminum foil on the bottom rack of the oven you intend to use.

    • This is to catch any drips from the oil coated pan.

    • Pre-Heat the oven to 350 degrees Fahrenheit .

    • Place the oil coated pan or skillet face down onto the top rack of the oven.

    • Allow the pan or skillet to bake for 1 hour at 350 degrees Fahrenheit.

    • Once the hour is up, turn off the oven, but do not remove the pan yet. Allow the pan to cool down with the oven over the next 45 minutes.

    • Remove the pan from the oven. Then apply a final, and extremely light, coating of vegetable oil to help smooth over any irregularities.

    • If the pan is still hot, use oven mitts to remove it. Burns hurt.

Conclusion

The skillet is now completely restored, good as new. For the best results, reapply the last thin coat of vegetable oil after the next few uses of the cast iron pan or skillet.

Ya, cast iron has some pain to clean. It takes lots of time to clean properly. In this type situation, I like to use healthy ceramic cookware https://healthyceramiccookware.com/. It healthy and safe than iron cookware.

The ceramic coating eventually gets chipped, exposes the CI. CI is not dangerous except in the hands of a mad house wife.

Very good friend.

This to restore a Cast Iron that has not maintained. This has nothing to cleaning regularly.

For regularly clean I put water in it and heat to a boil, dump, and whip. I’m done.
