You actually can wash a cast iron skillet. The old rule against it is a myth. Modern dish soap is gentle enough not to strip your skillet's seasoned, non-stick layer. The only things that will truly damage it are soaking it in water and putting it in a dishwasher.
No problems! I was taught by my grandmother to NEVER use soap in a cast iron pan. Wipe it out, use hot water to loosen any stuck on bits and dry the pan completely. If it needs to be scrubbed, use hot water and salt, dry it and wipe it down with a little bit of fat, usually bacon grease.
Instead, Amidor recommends “cooking with cast iron once or twice a week, especially if someone has iron-deficiency anemia and no issues with too much iron in their diet.” Preparing a more acidic dish, or something with a lot of moisture, is likely to absorb more iron from your pot or pan.
Washing cast iron is perfectly safe. Contrary to common myths, modern dish soap will not strip a pan's polymerized oil seasoning. However, leaving cast iron soaking in water or failing to dry it completely will cause it to rust.
Yes, you can absolutely use Dawn dish soap on cast iron.
The best way to clean a cast iron skillet is by scrubbing it immediately after cooking while it is still warm, using a stiff brush or a paste of coarse salt and water. Avoid dishwashers and harsh scouring pads, and always dry it thoroughly on the stove and rub it with oil to maintain its non-stick seasoning.
A cast iron skillet is ruined primarily by rust from soaking or improper drying, warping from extreme thermal shock (like cold water on a hot pan), or cracking if dropped. While most seasoning issues are reversible, letting rust cause deep pitting, or fracturing the iron, destroys the cookware permanently.
From a food-safety standpoint, the surface of a cast iron pan during cooking easily reaches upwards of 300 degrees, which is high enough to kill any bacteria that don't get washed away. You will not get sick from maintaining your pan this way.
If you are able to clean the skillet out by simply wiping it out, stop here. Having a small amount of oil after cleaning is not a problem. In fact, keeping a pan from drying out is an important part of long term maintenance. Over-cleaning your cast iron pan is unnecessary and will only stand to damage your seasoning.
Cleaning cast iron without soap is simple and relies on heat, gentle abrasion, and a thin layer of protective oil.
Iron deficiency occurs when your body lacks enough iron to produce hemoglobin, a protein in red blood cells that carries oxygen from your lungs throughout your body. When oxygen levels drop, you can experience a variety of physical and mental symptoms.
Health Benefits: If you're wondering whether cast iron or pure iron is better for your health, the good news is that both are excellent. They both leach small amounts of natural iron into your food, helping to boost your daily intake. Maintenance: Both need seasoning with oil to stay rust-free and smooth.
When it comes to natural, everyday beverages, prune juice has the most iron, delivering about 3 mg (roughly 17% of your daily value) per 8-ounce cup.
Clean your cast iron cookware after every single use. Doing this immediately while the pan is still slightly warm makes it incredibly easy and prevents stuck-on food, bacteria, and rust from ruining your seasoning.
The best oil for seasoning cast iron is one that is refined, neutral, and has a high smoke point (above 400∘F400 raised to the composed with power F400∘F / 204∘C204 raised to the composed with power C204∘C). Top choices include grapeseed oil, avocado oil, and canola oil. These oils polymerize effectively into a durable, non-stick layer without leaving a sticky residue.
Avoid cooking highly acidic foods, delicate fish, strong-smelling dishes, and sticky foods (like eggs) in cast iron. These can strip your pan’s seasoning, leach metallic flavors into your food, or leave behind lingering odors.
Yes, Dawn dish soap is perfectly safe for a well-seasoned cast iron skillet. Modern mild dish soaps are gentle enough to remove food debris and grease without stripping the pan's polymerized non-stick coating (seasoning).
When your paper towel turns black while wiping a cast iron skillet, it is typically just carbonized (burned) food bits, excess oil, or loose seasoning. It is entirely normal and not harmful to your health or the pan, though it can usually be resolved with a deeper cleaning and lighter oiling.
A cast iron pan is properly seasoned when it has a smooth, satin-black surface and repels water. To verify its readiness, perform the quick water drop test and paper towel test to ensure the layer of polymerized oil is intact and fully hardened.
Cooking with an uncoated cast iron pan is synonymous with cooking in its purest form. The untreated cast iron has no chemicals such as PFAS, PFOA and PTFE, making for a safe cooking experience.
The more you use a rusted pan, the more iron you'll consume in your food. It's best to avoid cooking with a rusty cast iron pan. If it's reached the point of corrosion or deep rust, throw it away rather than risk your and your family's health.
Cast iron skillets can last a lifetime—and even last for generations when cared for properly. Because they are built from a single, durable piece of metal, they do not wear out like traditional non-stick pans. Even if a pan develops rust or loses its seasoning, it can almost always be stripped down and restored.
Oil Residue & Splotchy Seasoning
How do you fix a badly seasoned cast iron pan? If you see some raised, splotchy residue on your skillet, which often looks like a spiderweb or spotted pattern, this is most likely some oil residue.
Yes, you do. Small amounts of iron leach from the pan into your food, which your body then absorbs. While it won’t cure severe anemia on its own, it is a proven way to boost your daily dietary intake.
