Re-conditioning a Cast Iron Skillet

[skeptic7]

I've used sandpaper and steel wool pads before. The Steel wool does a better job of getting into the corner where the pan bottom meets the edge. I think the sand paper is less messy or at least drier. This is mainly to clean off old finish if there is a thick layer. If there isn't enough finish, just wash and dry and rub a little oil on with a paper towel to remove the rust and bake.
I've had to refinish several times because I put too much oil on at once. Oil the pan lightly and then wipe off all the oil you can with a dry paper towel before baking it in the oven. Bake at 400 degrees, 350 degrees is to low to properly bake the oil into a solid surface.
Refinishing a cast iron pan is a lovely excuse for running the over for a couple of hours on a cold day. I might refinish my chicken frier. The bottom is fine but the sides are lumpy so it doesn't really NEED to be redone its just prettier.

Heating a skillet really hot on a stove top, will weaken the old finish so its easier to remove. I did this on a pancake skillet last year.

BakerAunt I talked with my cousin who use to collect iron wares and he said if you have rust to soak the pan in white vinegar and water for a little while then scrub and recondition,for heavy build up to soak in a mixture of red devil lye in a plastic container because it's caustic like the heavy rubbermaid containers for several days,for 5-10 gallons of water use about a can or 2 and you can't get it on your skin,use rubber gloves to get out of container,he said he'd soak several pans for a week or more,check them and scrub and replace them till it took all grime back to new condition,he said never put them in a fire.Just wanted to share what he said.

Thanks, Joan. That is interesting and makes sense for someone doing a number of pots at once. I wonder where he dumped the lye mixture when he was done. 🙁 At least I just have the one pan.

That is a good hint about the rust. My husband used vinegar to clean the rust off a used jointer he bought, and it worked well.

We had another rainy day, so I have not yet tried the oven cleaner, which according to my husband contains lye.

Lye is commonly used as a drain cleaner, so dumping it down the drain is one option.

Lye might start to eat through the pipes if there isn't a clog. Adding a strong acid to neutralize the lye would be dangerous -- it might cause an explosion as the two chemicals react. You should wear goggles as well as gloves when dealing with lye.

I don't think I'd pour it in the drain either,my cousin said he'd pour it around trees ,not a flower bed as it might be too much lye,But ashes from your fire place is basically just potash and they are good for flowers or trees.Old timers use to bury a can of potash under a pecan tree and as it deteriorates it leeches in soil for abundant pecans.
My husbands grandfather one time had a commode stopped up and he over did the red devil lye poured 2 cans in it and he said it started smoking and cracked the commode with an explosion.He said his Daddy told him don't do it but he was hard headed lol.

Maybe pour it down the drain slowly as you run the faucet full open to dilute it.
