Wash your cast iron cookware by hand. You can use a small amount of soap. If needed, use a pan scraper for stuck on food. For stubborn, stuck-on food, simmer a little water for 3-5 minutes, then use the scraper after the pan has cooled.
It is generally not recommended to use cast iron cookware that is heavily scratched or has deep gouges in the cooking surface. This is because the scratches can create a rough surface that may trap food particles, making it difficult to clean and potentially harboring harmful bacteria.
After you've used your skillet, use a sponge to scrub it with water. But don't let it soak in water, as this can cause rusting. If it still needs a bit more attention, add some kosher salt to the pan and scrub with a damp sponge.
Exposure to iron oxide, a substance sometimes encountered in cast iron grinding, is a danger, as well. This substance has been associated with cases of pulmonary siderosis, an occupational lung disease. Iron dust is also listed by OSHA as a combustible dust.
This black residue from your cast-iron pan doesn't look great, but it's just seasoning and it's not harmful. Keep cooking in that pan, washing and drying and oiling it meticulously, and you'll see the issue clear up quickly.
If cast iron is left in the sink to soak, put in the dishwasher, or allowed to air dry, it will rust. It can also happen when you store your cookware in moisture-prone environments, such as a cabinet near a dishwasher, an open cabinet in a humid location, or stored outside.
Caring for Cast Iron
With soap if it needs it. Scrubbing with the rougher side of a sponge if it needs that to remove food particles. Don't use steel wool, and do dry it completely. Then, put another tiny bit of oil in and rub it all over, wipe it away, and put it over a burner for a few minutes.
All cast iron, whether natural or coated, has a much higher carbon concentration than other popular food-safe metals like stainless steel and aluminum. This means that natural cast iron is more susceptible to corrosion because when carbon combines with oxygen and water, rust forms.
That's why our simple cleaning steps have you rub oil into your pan after each use to ensure the seasoning remains for quality cooking. You can also season your cast iron cookware in the oven. This method adds a more thorough layer of seasoning onto the entire pan, strengthening the bond to the iron.
Decades ago, soaps were made with lye and vinegar, and they were too harsh for use on cast iron pans. They would indeed strip away oil and could remove seasoning. But today's soaps, especially ones that are made with eco-friendly solutions, are often too mild to remove seasoning.
Avoid scrubbing your cast iron with anything too abrasive, like a steel wool or stainless steel scouring pad, that might scrape off the desired build-up. While your cookware is cool enough to touch, wash it with a few drops of mild dish soap and a stiff bristle dish brush. Rinse the pan.
A 2022 study found that scratched pans coated with these chemicals release thousands to millions of microplastics and nanoplastics. You should avoid using any scratched or dented nonstick pan to avoid exposure to potentially toxic chemicals.

Cooking with a cast iron pan that has a little bit of surface rust on it isn't likely to hurt you. If your pan is seriously rusty or has visible rust flakes, you shouldn't cook with it until the rust is removed and the pan is washed and re-seasoned.
They are most likely carbon deposits. This happens due to overheating of fats and oils. Using an oil with a low smoke point will carbonize at high temperatures and cause residue from the pores of your pan to rub off onto your food. While unappealing, they won't hurt you in such a small amount.
Cooking on unseasoned cast iron can result in sticking, rusting, and a myriad of other issues (some of which are outlined above).

Over-cleaning your cast iron pan is unnecessary and will only stand to damage your seasoning.
Common cooking oils like olive oil will gradually produce seasoning, but won't be as effective as grapeseed oil. Canola, other vegetable oils, and shortening are a little better.
