I've only bought the pan a week ago and used it three times. Hot dogs, eggs, and steak.

When I'm done I clean it with a scrubby sponge and once with a little bit of detergent, then put it on the stove to dry quickly. Then while it's hot I smear maybe a teaspoon of vegetable oil on it with a paper towel "brush".

In between uses it's wet with oil, as you can see in the picture. How much residual oil should there be? I had the impression that it would be dryer.

Also, how much should I scrub? I am not going to leave crust of beef on there, but I also don't think it's supposed to be scrubbed back to new smoothness.

You can scrub a cast iron pretty hard if you're just using soap and a sponge. I'm sure you've heard that you shouldn't use soap with cast iron, but that advice comes from a time when lye was an ingredient in most soaps. Dawn isn't going to strip the seasoning off your pan.

You can scrub the hell out of it too, but you have to be care about abbrassives in the pan. A new dish sponge will scrub burnt stuff from your pan. A new dish sponge plus something coarse like a bit of kosher salt will strip the seasoning. That is useful if you want to entirely strip and redo the seasoning, but for routine cleaning you want to make sure you're scrubbing it, not sanding it.

Oil in the pan between uses: I'm super neutral on this one. I leave mine dry between uses, and I have to touch up the seasoning every three months or so. My parents store theirs with a very thin sheen of oil (pour in a drop of oil, wipe it away with a towel until there are no visible pools or raised lines of oil) and they almost never need to re-season. Imo both are reasonable, I personally prefer the dry storage because occasionally touching up the seasoning feels like less work and less waste than oiling it after every use for storage.

I do the same as you after most uses. Scrub with dawn, rinse, dry. Done.

Thank you for sharing. I'll really need to try some of these various methods.

When I cook something that leaves gunk that sticks to the pan I usually put it under the tap when hot and rinse it, stirring with a dish brush while the water is boiling. Cleana everything. Heard someone warninf against thermal shock and cracks to the pan. Nothing yet for 20 years.

This is good, I like this plan.

Dry, no oil whatsoever, because I wash mine by hand with soap and water - I'm a monster, right?

Nope. Mine are slick, so slick that with a little water on them it feels like they're oily.

So mine are put away bone-dry. I seasoned them with Flaxseed oil - total game changer. I've even seasoned aluminum baking sheets with it, now they're nearly stick proof too.

America's Test Kitchen figured this out by testing several oils and methods.

The more passes you can do, the better. I'm probably between 5-10 layers on most of my pans now, and it's smoother, slicker than the pan my grandmother used for breakfast for decades.

404 on the first. I've heard it comes up pretty but can get very flakey

I commit all kinds of cast iron crimes, but honestly, just re-seasoning pans is fine. Oil and wipe with a paper towel. Cast iron can absolutely take a cleaning.

I fully clean mine with soap because I make spicy tacos at night in it, then flapjacks the next day. Nobody wants spicy flapjacks.

The real key is unscented/unflavored soap. then, reseason with just enough oil to keep it shiny. If you make it your main pan, it will get nice and seasoned from years of use. :)

Clean the pan like you’re doing. Some say don’t use detergent, but I do. Once the heavy food bits are gone, I dry it off. Then put a tablespoon of avocado oil in the pan and crank up the heat until it’s hot and shimmering. I then wipe it, let it cool and put it away. This builds up the seasoning so that the surface is protected from rusting and to maintain a non stick surface.

[–] [email protected] 2 points 1 day ago (1 children)

This, but you should heat it until it just begins to smoke, then turn it off and let cool. The seasoning is built up by the polymerization of the oil. If done correctly, it will eventually build up a ceramic-like coating that is non stick. This is why the detergent myth doesn’t matter. You aren’t soaping away a polymerized coating out of the pan.

You also just need to use enough oil to coat the pan. So save money on not wasting oil. I use a couple to half dozen drops and wipe it out with a towel. If the coating goes on too thick, it can get brittle and chip off in parts, leaving a craggy layer. The idea is to build up a tiny layer lots of times over the years.

Thank you, I appreciate the advice.

[–] [email protected] 10 points 1 day ago

Youre going to get a million and one recommendations of oil on this thread as well. For example I use grape seed oil since it has a very high smoke point.

Some oils don't work, but if it's mentioned in this thread it's likely fine.

[–] [email protected] 1 points 1 day ago

You want to make sure you aren't using a lye-based soap. Dr. bronners falls in this category and can take a bit of your seasoning off, at least if they haven't changed their soaps in 10 years. It shouldn't ruin your seasoning, but it can remove some of it and leave it a matte finish. Dawn and normal grocery store dish soaps won't hurt anything.

[–] [email protected] 5 points 1 day ago (1 children)

That's the neat part. You don't need anything between cooking sessions. If you always cook with a bit of fat, the seasoning will build up over time and will keep the pan protected from rust. I deliberately reseason maybe a couple times a year.

The truth is, cast iron and carbon steel don't need excessive babying. My only tools to keep mine in top condition are a flat spatula and a thick bristled brush (natural fibers, no plastic as it could melt). After cooking, I always do the following :

  • Deglaze the pan over high heat and unstick everything left with the spatula
  • rinse, scrub with the brush, rinse again
  • dry with a dish rag
  • store somewhere dry
  • repeat the next day

No need for soap, reheating, constant seasoning upkeep or oiling. If your seasoning isn't flaking off, which it shouldn't, it's good to go. Even a few rust stains or gouges in the seasoning can be brushed off and seasoned over.

This sounds doable. Thank you!

I have this same pan. It's used daily. I find with ring molds for the eggs it's perfect for 3 breakfast sandwiches or 4 burgers.

After use, I wipe it down with a paper towel to remove excess oil. I haven't noticed any stuck on food.

Every 2-4 weeks, I'll wash it with a little scrubbing and dish soap. After the scrubbing, I'll dry with a paper towel or dish rag and place it on the burner at high. After the pan heats through, I add about a tsp of vegetable oil and rub all over the cooking surface with a paper towel. After the surface is coated, I take another paper towel and wipe it agian.

Thank you. I appreciate all the input, but it's funny how different people's opinions are!

In the restaurants I worked we used salt for cleaning, never a detergent. Couple of tablespoons of salt and for scrubbing cloth, spunge or half a potato. Scrub, discard salt, rinse with water, dry and apply a liitle arachide oil afterwards.

I rarely oil my cast iron pans, only when I notice they are "less shiny". When needed, I clean them thoroughly, dry well, then, put a little olive oil, just enough to cover all the surface and put it to high heat for around 5 to 10 minutes. To apply oil it's better to use a cloth than paper towels because some paper particles could stick to the pan. Wash your pans as soon as possible with not much of dish soap, preferably with warm water and dry immediately.

[–] [email protected] 8 points 1 day ago

While the type of oil isn’t critical, I would use something with a higher flash point and less flavor than olive oil.

Peanut, canola or vegetable oil are my preferred oils for seasoning.

I use a carbon steel pan, as I find the smoothness much easier to keep clean (smaller pores than cast iron).

I spent some time seasoning it at first (6 layers is a little overkill, I did 8, don't be me), and now I just lightly scrub/wipe off any food or oils after cooking and reseason maybe monthly if that. My pan is dry and clean between uses.

If I burn food or it sticks for some other reason, I scrub harder. If I need an abrasive, I reseason afterwards.

Reseasoning includes cleaning thoroughly with detergent to get any soot off. Then rubbing in oil with cloth, and drying off as much as possible with a clean cloth before popping it into the oven for an hour. Wiping it down gives thin, even layers.

If need be I repeat up to three times.

I've used them for 4-5 years now without issue.

My cast iron grill pan absorbs more flavors though, so that needs a lot more cleaning if switching between cuisines.

I've had a few cast iron pans and a carbon steel pan for a few years now. I just wash them with dawn dish detergent (make sure whatever soap/detergent you use doesn't contain lye) and a sponge until all the food bits are gone and the water cleanly skids off the pan. After, I shake the water off and hand dry with a cotton dish towel. I don't put oil on them unless I'm gonna store them for months at a time.

You mentioned your pans are new so the water may not slide off like a well used and seasoned pan so just scrub and rinse until the food bits are off. If there are any difficult bits, you could buy a plastic dish scraper or just gently scrape at it with a metal spoon. Don't worry too much about damaging the pan when washing; cast iron has lasted many families many decades of cooking and abuse.

Just make sure not to drop it or heat/cool it too quickly and it'll be fine

Scrub it back to the seasoning, which shouldn't take a lot of scrubbing. I use the blue sponge and I know I've got off all the food bits when the water just slides off the surface but doesn't look slick afterwards. If I wipe a little oil onto it then the cloth or paper towel should not look dirty.

[–] [email protected] 3 points 1 day ago

Thank you, that helps.

[–] [email protected] 5 points 1 day ago (1 children)

I imagine there are many ways to nicely clean cast iron but I ended up buying that little chain mail scrubber that Loge sells. I rinse it, sometimes with hot water, scrub it fairly well, then put it on the stove and heat the water away so it doesn't rust.

[–] [email protected] 2 points 1 day ago (1 children)

No particular oiling regime?

[–] [email protected] 2 points 1 day ago (1 children)

Oh right. Every now and then (maybe every year or two if I've been using it a lot or if it starts getting a little gnarly) I'll use a tiny bit of soap when I clean it then I'll re-oil it, usually with olive oil. Maybe not best practice but it's been working fine for me.

Not oily at all. Use a towel to clean off the excess oil.
