Cast iron pans are often marketed as non-stick, a quality that develops over years of use. The use of dish soap on cast iron pans has been a topic of debate, with some sources claiming that it can ruin the pan by stripping its seasoning. Seasoning is a layer of polymerized oil that is baked into the pan, giving it a non-stick surface. However, others argue that modern dish soaps are mild enough to only rinse away surface oil and food debris without affecting the polymerized oil layer. While it is generally agreed upon that harsher cleaning agents like lye and vinegar should be avoided, the use of mild dish soap on cast iron pans remains a divisive topic among cooks.

Dish soap won't ruin cast iron pans, but harsher cleaning methods might
While it was once believed that dish soap could ruin cast iron pans, this is no longer the case. Older dish soaps were made with lye, which would strip the seasoning and damage the pan. However, modern dish soaps are much milder and will not affect the polymerized oil layer—or seasoning—of a well-seasoned pan. In fact, many cast iron manufacturers and experts now endorse the use of soap when cleaning cast iron.
That being said, if your pan is not properly seasoned, or if you use too much soap, it is possible to strip the seasoning. To avoid this, it's important to season your pan before using it for the first time and to use soap sparingly when cleaning. After washing your pan with soap, be sure to dry it immediately and then add a new layer of oil to the pan.
While dish soap is generally safe to use on cast iron, there are some harsher cleaning methods that should be avoided. For example, never use power cleansers or aerosol oven cleaners on your cast iron, as these can quickly strip the seasoning and damage the pan. It's also important to avoid soaking your cast iron pan in water, as this can lead to rust. Instead, clean your pan with a small amount of soap and water, then dry it thoroughly before adding a new layer of oil.
In addition, it's best to avoid using steel wool or metal scrubbers to clean your cast iron, as these can also strip the seasoning. Instead, use a nylon brush or sponge to clean your pan gently. By following these guidelines, you can keep your cast iron pans clean and well-seasoned for many years to come.

It's best to dry cast iron pans immediately after washing
It is best to dry cast iron pans immediately after washing them. This is because water can quickly cause rust to form on the pan. While it is safe to use soap to wash cast iron pans, it is important to note that doing so may strip the pan of its seasoning—a thin layer of polymerized oil that gives the pan its non-stick properties.
To dry a cast iron pan, use a paper towel to wipe it down after washing. Then, heat the pan over a stove eye on medium-low heat to remove any remaining water. Turn off the stove eye and pour a small amount of high-temperature oil, such as flaxseed, vegetable, or canola oil, into the pan. Use a paper towel to spread the oil across the pan, inside and out. Allow the pan to cool completely, and then wipe away any excess oil before storing the pan.
If you notice that the seasoning on your cast iron pan is becoming thin, you can restore it by rubbing the pan down with oil and baking it. This will help to build up the seasoning and improve the pan's non-stick properties.
It is important to avoid letting cast iron pans soak in water, as this can lead to rusting and damage to the seasoning. Instead, wash and dry the pan immediately after use. Additionally, do not use steel wool or metal scrubbers to clean cast iron pans, as these can also damage the seasoning. Instead, use a nylon brush or the soft side of a sponge.
By following these steps and drying your cast iron pans immediately after washing, you can help to maintain the seasoning and ensure that your pans remain non-stick and in good condition for years to come.

You can use soap, but you don't have to
You can use soap to clean your cast iron pans, but it is not necessary. Older dish soaps were made with lye, which would strip the seasoning and damage the pan. However, modern dish soaps are milder and will not damage the polymerized oil coating on the surface of the pan. If you do use soap, use a small amount and avoid soaking the pan or scrubbing it with steel wool. Instead, use a nylon brush or sponge to clean the pan, and be sure to dry it immediately after washing.
If you prefer not to use soap, you can simply wipe out the pan with a paper towel and heat it to dry it, killing off any bacteria. You can also use a pan scraper to remove stuck-on food and debris, or add some water to the pan and heat it to loosen any stubborn residue.
Some people choose to season their cast iron pans before using them, as it helps to reduce sticking and build up the nonstick surface. This can be done by rubbing the pan with oil and baking it, or by adding a thin layer of oil after cleaning and heating the pan until it smokes.
While it is safe to use soap on cast iron pans, it is important to use it judiciously. Try not to use it if you can, and if you do need to use it, only use a small amount. By following these simple steps, you can keep your cast iron pans clean and well-maintained without relying heavily on soap.

If you use soap, make sure to season the pan before cooking with it
It is generally agreed that using soap on a cast iron pan will not ruin it. However, it is important to season the pan before using it to cook. This is because the seasoning creates a non-stick surface, which is prized in cast iron pans.
Seasoning is a layer of polymerized oil that is baked into the pan. It is what gives a cast iron skillet its non-stick or "easy-release" surface. The more you cook with your cast-iron skillet, the more this layer of polymerized oil builds up, and the more its easy-release properties are enhanced.
If you do decide to use soap, it is important to take a few steps to ensure your pan is ready to use the next time you cook. Firstly, never let the pan soak in water and always dry it immediately after washing, as water can quickly cause rust. Use a hard-bristle brush or the scrubbing side of a sponge to loosen any food and debris. Pour a small amount of mild dish soap into the pan, and clean the brush or sponge. Rinse the pan and dry it immediately. Heat the pan over a stove eye on medium-low heat to remove any remaining water. Turn the eye off. Pour 1/2 teaspoon of high-temp oil (such as flaxseed, vegetable, or canola) into the pan. Use a paper towel to spread the oil across the pan, inside and out. Let it cool completely, then wipe away any excess oil and store the pan.
If you have any stuck-on bits that won't come off, you can loosen them by adding some water to the pan and heating it over medium heat for three to five minutes. You can also burn off any tough residue on a hot burner, then rinse with cold water and wipe with oil while the pan is still warm.

If you don't want to use soap, hot water and a gentle scrub should do the trick
If you don't want to use soap, there are alternative ways to clean your cast iron pan. Firstly, it's important to note that cast iron pans should not be left to soak in water, as this can cause rusting. Instead, you can use hot water and a gentle scrub to clean your pan. Bring some water to a boil in the pan, then let it simmer until the water evaporates. You can then wipe out or scrub the pan with a non-abrasive sponge or a soft cloth.
If there are stubborn bits of food still clinging to the pan, you can try adding a bit of kosher salt to the pan and scrubbing with a damp sponge. The salt acts as an abrasive cleaner and will help to loosen the food without damaging the seasoning. You can also try using a pan scraper to remove stuck-on food and debris before cleaning.
Once you've cleaned the pan to your satisfaction, rinse it well and place it on the stove over medium heat to dry. When the pan is completely dry and still warm, use a cloth or paper towel to coat it lightly with vegetable oil or another light oil, such as canola oil, to prevent rust.
While it is possible to clean a cast iron pan without soap, it's important to note that mild dish soap will not damage a well-seasoned pan. If you choose to use soap, simply follow the same steps as above, adding a small amount of soap to the pan before scrubbing with a non-abrasive sponge or soft cloth.
