Yes, you can absolutely use Dawn dish soap on cast iron.
No, Dawn dish soap is not bad for cast iron. Modern, mild dish soaps are perfectly safe and will not strip a properly seasoned pan. The old rule against using soap comes from historical, harsh lye-based soaps.
You can use mild, grease-cutting dish soap—like Dawn Dish Soap—or specialized cleaners to clean cast iron. The "no soap" rule is a myth stemming from harsh lye-based soaps of the past. Today’s mild detergents safely lift stuck-on food and grease without stripping the protective seasoning.
For individuals with diagnosed iron deficiency or anemia, cast iron cooking alone is not going to provide enough iron, and additional dietary modifications or iron supplements may be necessary." It's also worth noting what type of iron you'll absorb from employing this material in the kitchen.
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.
Detergents aren't made with lye, so can't be soap. Either way you still shouldn't use soap with cast iron, but can use detergents, though there is no reason to do so. You can easily clean well maintained cast iron without it.
Cooking with cast iron is generally very healthy and safe. It is free from synthetic chemicals like PFOA and leaches small, beneficial amounts of dietary iron into your food. This added iron can naturally supplement your diet, which is especially helpful for preventing or managing iron-deficiency anemia.
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.
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.
To reseason cast iron after washing with soap, dry the pan immediately and completely on a warm stovetop, then rub a very thin layer of high-smoke point oil (such as canola or grapeseed) over the entire surface. Heat the pan in a 450°F–500°F oven for one hour to restore the polymerized coating.
If you are doing a full oven seasoning (applying a very thin layer of oil and baking the pan), 3 to 4 coats are ideal to build a solid, protective foundation. Most factory-preseasoned pans are lightly coated, so adding 2 to 3 extra layers prevents sticking and rusting.
Cooking eggs in cast iron without sticking comes down to three basic rules: use medium-low heat, preheat the pan properly, and always use a cooking fat. Cast iron naturally retains heat, so starting too hot or skipping the oil guarantees the eggs will bond with the surface.
No, it is not bad. Modern, mild dish soaps are completely safe to use. The old "no soap" rule comes from decades ago when soaps contained harsh lye, which stripped the skillet's seasoning. Today's gentle dish soaps simply cut through grease without harming the baked-on, nonstick layer.
Most modern dish soaps do not contain lye (sodium or potassium hydroxide). They are formulated as synthetic detergents using petroleum-based and plant-derived surfactants, which eliminate the need for harsh alkali lye to cut grease.
You can use mild, grease-cutting dish soap—like Dawn Dish Soap—or specialized cleaners to clean cast iron. The "no soap" rule is a myth stemming from harsh lye-based soaps of the past. Today’s mild detergents safely lift stuck-on food and grease without stripping the protective seasoning.
When your iron is low, the most common craving is ice (a condition called pagophagia). You might also crave non-food items like dirt, clay, starch, or paper (known as pica). Additionally, your body might push you toward salty snacks or sugar for quick energy.
Iron is primarily drained from the body through blood loss, including heavy menstruation, gastrointestinal bleeding (ulcers, cancer, or medication side effects), and routine shedding of intestinal cells. Dietary factors, such as high intake of calcium, coffee, tea, and fiber, inhibit absorption.
The heart is the organ most heavily affected by chronic or severe anemia. Because anemia causes a shortage of oxygen-rich blood, the heart must work harder and pump faster to meet the body's needs, often resulting in arrhythmias, an enlarged heart, or, in severe cases, heart failure.
What Not to Cook in a Cast-Iron Skillet
Yes, you should wash your cast iron pan after every use to remove food debris, fats, and bacteria. Contrary to popular myth, a well-seasoned pan is highly resilient, and washing it correctly won't strip away its protective, non-stick coating.
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.
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.
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.
The difference between cheap and expensive cast iron comes down to weight, surface finish, and craftsmanship. While budget pans are thick, heavy, and have a pebbly texture, premium pans are machined to a silky smoothness, weigh significantly less, and heat up faster.
