#2 isn't ALWAYS bad...

Chainmail is a bit aggressive for cast iron seasoning; I use kosher salt and a paper towel. That said, I don't think thats whats causing your issues. Can you snap a pic or two of what you're talking about? The only flaking I've ever seen on cast iron was from ANCIENT seasoning that was actually too thick, and starting to delaminate from itself.

I'm using a Lodge cast iron skillet on a gas rangetop and the bottom of skillet looks like its more bare metal than seasoned. Is this normal or is the flame removing seasoning that should be on the bottom of the pan? Is it a problem and should I be reseasoning the bottom/sides? No problems with seasoning on the inside of the pan.
I have the same type of stove, and the bottom of my lodge is also starting to lose its seasoning, but it doesn't seem too bad? Can't hurt it to put a little more seasoning on the bottom next time you need to preheat it in the oven.

I've started making tortilla's at home and have been using my cast iron skillet as a comal. My problem is that after a half dozen or so the residue starts to burn and stick. I've tried lowering the heat which helps that problem but then the tortillas aren't as nice. Any tips for preventing this from happening? The seasoning usually seems fine, it's just this one application.

It may be cheating and inauthentic, but I've taken to adding a little fat in my corn tortilla dough, just a glug of canola oil, and I don't get the stuff stuck on my cast iron griddle now. That's not why I add the fat, just a convenient consequence.

for comparison, here's what it looked like when freshly seasoned:



I often cook things that leak a lot of liquid into the pan and harden there, so I will rinse the pan with water, gently scrub it with (what I call) a kitchen sponge (link to approximately what I mean, because apparently an american kitchen sponge is generally softer?) then dry with a paper towel (which now start to tear due to the holes in the seasoning).

Putting the pan back on the heat so as to evaporate any water (and occasionally adding a bit of oil, heating the pan back up, then turning off the heat and wiping when the oil starts smoking) doesn't seem to work.

Looks like flaking seasoning. What did you season with originally?

For now, go at it with some wire wool/a brillo pad and take all that seasoning down to the bone, then start again. If you can't get it off or you're not happy with it, oven cleaner works very well and might be what I'd go for. Using vegetable oil or lard to reseason works fine, if you were using flax then the finish tends to be a little more fragile.

Reseason it either way, cook with it, then each time you feel it needs a proper wash scrub the poo poo out of it, before heating and oiling. Any seasoning that doesn't make it through the scrubbing didn't deserve to live, that sponge isn't harsh enough to damage it. Always do the heat + oil step after washing it. Long term, you're probably just not cleaning it viciously enough and anything that builds up enough to flake off is then taking what's underneath with it.

It might also be that cooking liquids in it isn't the way to go and you'd be better off with a saucepan sometimes, use it for the initial step of frying veg and stuff, then tip the veg into a saucepan, deglaze with some water and tip that in too, then wash the cast iron if it needs it and cook that way. Try not to cook in it without adding a little oil or butter first.

You can generally clean off anything that's stuck to it by heating it on the stove a bit to dry it out, throwing in some coarse salt and a little oil and scrubbing it with some paper towels, just to mix things up and so you don't have to wash it in the sink so often.

this is fine



I take a near-opposite approach to good success.

First, the easiest thing to change about your care is the type of fat. The best oils for good seasoning readily "dry" into polymerized oil. Lard used to do that, but factory-farmed pigs just make different lard these days. The theoretical best choice is organic flaxseed oil (must be 100%, must require refrigeration), but that smells fishy and so I only use it for the very first seasoning of a pan. For everyday cleaning & re-seasoning, it's best to stick to, in order from best to worst: safflower, soybean, sunflower, canola (sort descending).

"Just cook on it, clean with salt" AKA grandpa's method will get you something that works decently for cooking meats, but it'll be far from true non-stick, it'll be fragile (soap will dig past any weak layers, which is where "my roommate used soap, do I kill y/n?" comes from), and everything you cook on it will taste like bacon (mostly a good thing, sometimes not). Don't try to cook anything delicate or particularly sticky in it. If that's fine with you, keep cooking, gingerly scrub it, never use soap, and treat it like gramps used to: add more oil and grease on top of the old stuff. If your pan is oily, you'll get a bit of nonstickness, but it's a much nicer experience with "real" seasoning:

Real seasoning is polymerized oil, which has bonded with your pan to the point that scrubbing hard with soap doesn't damage it. You should be able to wipe a dry cast iron pan with a napkin and your napkin should come off 100% clean, no oil or crud. I got this from an oft-cited guide, which was verified by the ATK guys. It also happens to agree with this thread's OP:

Bob Saget IRL posted:

It's cast iron. It's a metal that's been used to conquer peoples and forge empires. You're not going to destroy it on your stove, grill or campfire. You may screw up the seasoning, but chances are, you will only ruin what wasn't really any real seasoning anyway. Why? Because you don't wash your pan.

Wash your pan? Yes, wash it. My laymen's way of explaining is: the fats that stick to the pan, will stick to the pan. A good, quick wash with a thick thistle plastic brush and soap will not take off seasoning. What does come off was not polymerized, and is not seasoning.
I've done the whole coarse salt and heat and oil thing, and it works to a point, but seemed to take more time and effort after more uses of the pan. Washing like a normal dish has provided the best results. But, drying is an additional step worth taking.

DO NOT SOAK YOUR PAN, OR LET WATER REST ON IT. Rust is bad, Mmmmkay. After you wash it, dry it well with paper towels. Put it back on the stove over a med-low heat, and let the heat take out the rest of the moisture. Once it's thoroughly dry, sprinkle a bit of vegetable oil (or oil with a higher smoke point [olive oil is not a good oil for this]), and wipe it all over the pan until it's just about dry. It's oil, so you're are not going to be able to wipe it all out, and that's the goal. Do the inside, handle and underside; whatever oil you can't wipe out is the perfect amount to leave. You don't want to leave excess oil in the pan, because it starts to get sticky and catch dust and what have you. The tiny bit of oil you leave, you want to polymerize. Leave it on the stove until it starts to smoke. Just when it starts to smoke, turn the heat off {this is why I use med-low heat, because you don't have to be very mindful).

(I added bolding to that last bit)

It's a lovely thing to be able to scrub a pan with cast iron and soap with impunity, and to not have rancid old oil in my pan. Bacon fat is good for flavoring, but I can easily add some from the jar in my fridge if I need it.

Here's my testimonial:

Back when I used grandpa's method:


1 year of weekly use:

4 years of nearly-weekly use:
one small dry spot, I might try copper wool to scrub that part down and re-do the flaxseed oil.

Why am I so bad at this? :(

My old Lodge pan has had this kinda dull, spotty pattern of rust colored dots on it for the many years I've owned it. I haven't been using it regularly or taking good care of it, but I haven't been leaving it out in the rain either. I scrub and scrub, then reseason 3+ times with vegetable oil, but I can't seem to do anything about this dull, spotted, red-brown layer all over the thing. Is this even rust? Do I just need to scrub harder? Should I break out the sand blaster? I know "use it more" is the solution for all cast iron problems, but if this is actually rust, then I'd like to take care of it before I start using it regularly.



Here's a pic with flash. It makes the spotted rust (?) pattern easier to see:

I think, just cook on it and that'll go away. My little pan looked like that after I reseasoned it, just hadn't had enough layers build up. From what I gather, Lodge aren't the smoothest of pans to start with.

I seasoned my new carbon steel pan, following the directions with doing some potato peels, salt, and oil. And then I took an oil soaked paper towel and oiled up the rest of the pan and stuck it in the oven at 400° for an hour. It looks like I had too much of a layer of oil as there were some tacky spots on the cooking surface. I stuck it on the stove top to try and cook those tacky bits into the rest of the seasoning. I guess it sort of worked but now I have bumps all over. And a bit of the seasoning flaked away.

Should I just start over with a brillo pad and re-season this thing?

Story as old as time. Got the oil on too thick. If you don't want to be annoyed every time you use it, brillo down those high spots and reseason. Make sure the pan is warm (or hot) when you apply the oil as that will let you get it on more thinly. Then wipe it off before it goes in the oven. What you're looking for is a sheen from the oil, but if you can see any depth or streaks or whatever, it's too thick and needs to be wiped before you bake it.

so, here's a totally hypothetical question. which would of happened to my friend, not me, if it did but it didn't. let's imagine someone who isn't me made their spouse a delicious pair of Birthday Steaks. and then, in their wont of coarse kosher salt, attempted to clean the surface by leaving it under a broiler until the fire alarm went off.

obviously my monkey's uncle has then taken the straight edge of a metal spatula and attempted to physically scrape off the crust, to limited success. should m- my friend just keep broiling it again with an open window? i can't buy kosher salt, it burns my hands to touch.

It's not worth keeping, and you want it to be one solid layer, not overlaid old and new. The flaking is because your original seasoning was weak, and probably because you're not scrubbing it enough so more weak layers are surviving over the top when they shouldn't, adherding to the weak layer and then taking it off with it when it flakes. It's like a thick blob of paint can be chipped or peeled off, when a very thin layer might be harder to remove.

Use lard or flax or sunflower oil, a couple of passes through the oven should be enough to get a thin seasoning, then just cook with it and wash it afterwards until it's good, 6-7 times is probably overkill. It might look like that guys above, kinda orange for a while if you really took it down to bare metal, but it'll darken up as you use it. Take advice on reseasoning from above. v

Plum Island Animal Disease Research Center. Sounds charming.
The smoke point of extra virgin olive oil is 410 degrees, so if you're seasoning at 400 it very likely will not polymerize and will instead become gross and flaky. Regular olive oil is higher I think, like 470 or so, but it's definitely not recommended for seasoning cast iron.

I've got a couple of those and they're not useful to me. Anything they'd get, so would the brillo side of a sponge. The stubborn stuff like steak fond doesn't budge, and actually cuts into the plastic, unless I get the copper wool.

I'd guess salt would be next best as an abraisive, and chainmail sounds dumb as hell. Isn't it all round edges? Sure, it won't catch on your delicate seasoning if you've got a poorly seasoned pan, but it also won't catch on crud. I'm probably missing something there.

BUT THEY WILL
I've gone through the gamut of cleaning methods with my pans. Started with salt, then steel wool, then chain mail, but none of them really seemed superior to the others. Nowadays I just get some water boiling in it to loosen stuff up and just use my normal dish scrubber thing (nylon brush with scraper) with some soap. When I'm done cleaning I still wipe it down with some oil and leave it on low heat for a while and occasionally do another proper round of seasoning. It's way less hassle and the pan is in as good of shape as it was with any of the other methods.

I really felt like boiling water \ liquid either damaged the seasoning or emphasized the spots where it was uneven (by boiling in a very weird way).

No matter how much I scrub, I can't seem to get the rest of the seasoning off, even with oven cleaner. What happens if the seasoning is uneven, old and new?

Took a stainless steel scouring pad to the carbon steel pan which took a bunch of parts off that were probably less well adhered to the pan and smoothed out the sections that were from the tacky parts. Then I did another seasoning in the oven with a super thin layer, even wiping it down with a clean paper towel after I put it on there to make sure it was not too much. 500° f for an hour. This is how it looks. It feels smooth but it doesn't look great. Is this an okay seasoning job or will I need to somehow completely nuke this thing and start over. I don't have a oven that has a self-cleaning option.
