Dawn can strip seasoning from cast iron pans
There are conflicting opinions on whether or not Dawn Ultra can strip the seasoning from cast iron pans. Some people claim that they use Dawn regularly to clean their cast iron pans without any issues and believe that if the soap is able to bind to the pan and wash it off, then it wasn't properly seasoned in the first place. They attribute the stripping of the seasoning to weak spots that will eventually flake.
On the other hand, several people have reported issues with using Dawn Ultra on their cast iron pans, stating that it stripped away the seasoning and left their pans looking depleted. Some advise against using Dawn Ultra directly on the pan because it can bind to the fatty acids and strip away the polymerized oils, resulting in a loss of seasoning.
It is recommended to use a mild dish detergent or a small amount of soap with warm water to clean cast iron pans without damaging the seasoning. Boiling water and wiping the pan clean without the use of soap is also suggested by some. Overall, while some people have success using Dawn Ultra on their cast iron pans, others find that it negatively impacts the seasoning, so it may be best to exercise caution when using this product on seasoned cast iron cookware.

Dawn's degreasing quality is good for removing oil from pans
While some sources claim that Dawn dish soap can be used on cast iron pans without causing harm, others strongly advise against it. The primary concern is that Dawn's powerful degreasing qualities, which make it excellent for removing oil from pans, will also strip the polymerized oils that form the pan's seasoning.
Dawn contains solvent agents and sulfides that are highly effective at dissolving oils. When a cast-iron pan is heated with fat, the fat molecules polymerize, forming larger molecules that bind to the metal of the pan, creating the seasoning. The worry is that Dawn's degreasing properties will bind to these oils and strip them away, disturbing the seasoning, especially on a newly seasoned pan. This can make it more challenging to achieve and maintain an even and durable seasoned surface.
However, not all sources agree that Dawn will damage the seasoning. Some claim that today's milder dish soaps, including Dawn, will only rinse away surface oils and food debris without affecting the nonstick seasoning. One source suggests that if the soap can remove the seasoning, then it wasn't adequately seasoned in the first place. Additionally, some people choose to use soap to remove excess oil from their well-seasoned cast iron without causing harm.
While it may be possible to use Dawn on a cast iron pan without causing damage, it is essential to exercise caution. If you choose to use Dawn, it may be wise to test it on a small area first or opt for milder alternatives to avoid the risk of stripping the seasoning.

Dawn is not necessary to clean cast iron pans
While some people use Dawn to clean their cast iron pans, it is not necessary or even ideal. Cast iron pans are notoriously tricky to clean and maintain, but with the right care, they can last for generations.
Firstly, it is important to note that cast iron pans have a natural, non-stick finish, which is achieved through "seasoning". This is a process that builds up over time through use, creating a non-stick coating. This coating can be stripped by certain soaps and detergents, such as Dawn Ultra, which can bind to the fatty acids and oils in the pan, breaking down the seasoning. Therefore, it is recommended to avoid using these products directly on the pan.
So, what are the alternatives? Well, for a start, you can simply use a clean dish towel or paper towel to wipe down the pan, especially if it is only lightly soiled. You can also use a soft sponge with a small amount of mild dish detergent, or even just hot water. If there are stuck-on bits of food, you can use a plastic scraper or wooden spoon/spatula to gently lift these off while the pan is still warm, before giving it a quick rinse and hand dry.
For more stubborn residue, you can use a natural abrasive like salt or baking soda, with just enough water to make a slurry. You can also use a chainmail scrubber, which is designed to remove gunk without damaging the seasoning. After cleaning, it is a good idea to apply a thin coat of oil to the pan, such as avocado, olive, or canola oil, to maintain the seasoning and prevent rusting.
In summary, while some people use Dawn to clean their cast iron pans, it is not necessary and may even be detrimental to the pan's seasoning. With a little extra care and some alternative cleaning methods, you can keep your cast iron pan in great condition for years to come.

Other soaps can be used to clean cast iron pans
While some people believe that using soap on a cast iron pan is detrimental, this is a myth. The myth likely originated due to the fact that old-fashioned soap contained lye or borax, which could damage cast iron. However, modern soaps are very different and it is safe to use them on cast iron pans. In fact, mild dish soaps can be used to clean cast iron skillets. Lodge, a cast iron pan manufacturer, advises using a mild dish detergent for cleaning their pans.
It is important to note that soap should be used in moderation. Firstly, remove any stuck-on food or black residue from the surface of the pan with a paper towel. Then, clean the pan with hot water and a nylon scraper or brush to remove stubborn stains. If there is still residue on the pan, add a small amount of soap to the hot water and continue to scrape. Wash off the soap and dry the pan immediately with a towel.
It is recommended to reseason the pan after every cleaning session. Seasoning is a layer of oil that has reacted with the iron surface of the pan when heated, creating a non-stick layer that helps prevent rusting. To season a cast iron pan, apply a layer of oil and bake it in the oven.
Some people choose to use alternatives to soap when cleaning their cast iron pans. These alternatives include hot water, lemon juice and salt, or chainmail scrubbers. However, it is important to avoid using steel wool or metal scrubbers as they can remove the seasoning and make the pan less non-stick.

Cast iron pans can be cleaned without soap
While some people do use soap to clean their cast iron pans, it is not necessary. Cast iron pans can be cleaned without soap, and there are several methods to do so. Firstly, it is important to never soak the pan in water, as this can cause rusting. Instead, use a damp sponge or cloth to wipe down the pan after each use. For stuck-on food, simmer a small amount of water in the pan for 3-5 minutes, and then use a wooden or nylon spatula, or a pan scraper, to remove the food once the pan has cooled. If there are still stubborn bits of food, kosher salt can be added to the pan, and it can be scrubbed with a damp sponge. The salt acts as an abrasive cleaner without disturbing the seasoning.
Another method to clean a cast iron pan without soap is to use an oven cleaner solution. This method is suitable for pans with decades of carbon buildup from burnt-on grease. However, oven cleaners are highly toxic, so they should only be used outside or in a well-ventilated space, and it is important to wear rubber gloves to avoid chemical burns.
After cleaning, it is important to dry the pan thoroughly. The pan can be dried on the stovetop over low heat or in the oven at 200 to 300 degrees Fahrenheit to ensure all moisture is gone. Once dry, the pan should be coated with a thin layer of cooking oil, such as canola or vegetable oil, to prevent rust and maintain the seasoning.
While soap is not necessary for cleaning a cast iron pan, a small amount of mild dish soap can be used if desired. However, it is important to ensure that the pan is well-seasoned before using soap, as it can strip away the seasoning if the pan is not properly seasoned.
