If your cast iron pan is silver, it's likely that you've scrubbed off the seasoning, a layer of oil that's been polymerized at a high temperature to create a natural non-stick surface. This process is called seasoning and is done to give the pan natural non-stick properties. It's not harmful and can be fixed by re-seasoning the pan.

The cast iron pan has been scrubbed too hard, exposing the silver metal underneath
If your cast iron pan is silver, it may be because it has been scrubbed too hard, exposing the silver metal underneath the black coating. This black coating is known as "seasoning", which is created by cooking oil being baked into the surface of the pan, giving it natural non-stick properties.
When cast iron skillets are new, they need to be seasoned before use. This is done by washing the skillet with hot water and drying it completely. Then, a little bit of vegetable or olive oil is rubbed into the surface of the pan, and the skillet is placed upside down in an oven at 350 degrees Fahrenheit for an hour. After this process, the skillet will have a black, non-stick surface.
However, if the skillet is scrubbed too hard, this seasoning can be removed, exposing the silver metal underneath. This is what may have happened to your pan. If you want to restore the non-stick surface, you will need to re-season the pan. To do this, use steel wool or a chain-mail scrubber to remove any remaining seasoning, wash the pan with soap and water, and dry it thoroughly. Then, rub the entire surface with a neutral cooking oil, such as vegetable, grapeseed, canola, or sunflower oil. Place the pan upside down in an oven at 450-500 degrees Fahrenheit for an hour, then turn off the oven and let the pan cool.
It is important to note that cast iron skillets should not be washed with soap, as this can remove the seasoning. Instead, they should be cleaned by drying the pan thoroughly after washing, then rubbing a drop or two of olive oil into the surface. Additionally, metal utensils should not be used on cast iron skillets, as they can scratch the surface and remove the seasoning.

The pan has been seasoned incorrectly, resulting in a silver appearance
If your cast iron pan is silver, it may be because it has been stripped of its seasoning. This could be due to a number of reasons, such as incorrect cleaning or maintenance methods.
Cast iron pans are typically seasoned by applying a thin layer of cooking oil and baking the pan in the oven at a high temperature. This process is done to create a protective coating that gives the pan its classic black patina and non-stick quality. However, if the pan is not properly seasoned, or if the seasoning is not maintained, it can result in a silver appearance.
For example, if too much oil is used during the seasoning process, it can cause the pan to become sticky. This excess oil can then pool during cooking and form hardened droplets, which can be difficult to remove. Additionally, if the pan is not thoroughly cleaned and dried before seasoning, the oil may not adhere properly, resulting in a less effective barrier.
Another common issue is the use of incorrect cleaning methods or tools. Cast iron pans should be cleaned with mild soap and water, and dried thoroughly. The use of abrasive cleaning pads or tools can remove the seasoning, leaving the pan vulnerable to rust and giving it a silver appearance. It is recommended to use fine steel wool or a chain-mail scrubber for stubborn residue, followed by re-seasoning.
If your cast iron pan has turned silver, it is important to strip any remaining seasoning, re-season it correctly, and maintain it properly to restore its black patina and non-stick surface.

Using abrasive cleaning methods can remove the black seasoning, leaving the pan silver
Abrasive cleaning methods can be used to remove the black seasoning from a cast iron pan, leaving the pan silver. This can be done with steel wool, a metal scouring pad, or even a circular metal brush attachment for a drill. However, it is important to note that using abrasive cleaning methods may not be recommended as it can make the surface too smooth for seasoning to stick. If you do decide to use an abrasive cleaning method, it is important to reseason the pan after cleaning. This can be done by rubbing the entire surface of the pan with a thin layer of cooking oil, placing the pan upside down in an oven preheated to 450-500°F, and baking for an hour. Allow the pan to cool, and repeat as necessary to achieve the desired level of seasoning.
It is worth noting that the black residue on a cast-iron pan is typically not harmful and is often just a result of overheating fats and oils or burnt-on food particles. In most cases, it is not necessary to remove the black seasoning, and doing so may require some effort. Additionally, there are alternative methods for cleaning a cast-iron pan that are less abrasive, such as using salt or a stiff brush to scrub the pan, or boiling water in the pan to loosen stuck-on food.

Power tools or extreme heat can strip the seasoning, causing the pan to turn silver
Power tools and extreme heat are not recommended for stripping cast iron cookware as they can cause permanent damage. Power tools such as wire wheels or sanders can leave marks and alter the surface of the pan, affecting its performance and appearance. The pan may develop an uneven surface texture and become difficult to season.
Similarly, extreme heat methods like using a fire or hot coals can also lead to warping, discolouration, increased brittleness, and surface damage. These methods can be risky and may result in permanent damage to your cast iron.
Instead, it is recommended to use chemical methods like a lye bath or oven cleaner to strip the seasoning from your cast iron pan. While these methods require caution and safety gear, they are effective in removing the seasoning without causing damage to the pan's surface.
If you do choose to use power tools or extreme heat, be aware that your pan may require extra care and attention to restore it to a usable state.

The pan has been washed with soap, which can remove the seasoning and make it appear silver
It is possible that your cast iron pan is silver because it has been washed with soap. While it is generally believed that cast iron pans should not be washed with soap, this is a myth. In fact, it would take a lot more than soap to remove the seasoning from a skillet. The best way to remove seasoning is to bring the pan to high heat in an oven or grill. However, large amounts of soap can strip the seasoning off your pan. Older dish soaps were made with lye, which would strip seasoning and even damage pans. But today's milder soaps will only rinse away surface oil and food debris. They are not strong enough to affect the nonstick seasoning.
If you have washed your cast iron pan with soap and suspect that its seasoning has been stripped, you can easily re-season your pan. First, scour any loose edges or flaky parts of the seasoning away, wash the pan thoroughly with soap and water, and dry it thoroughly. Then, line the bottom of your oven with a sheet of foil or a foil pan to catch any drips, and preheat to 450-500°F. While that's warming up, use a cloth or a paper towel to rub the entire surface with a neutral cooking oil (like vegetable, grapeseed, canola, sunflower, or another oil with a high smoke point), thinly enough so that it doesn't visibly run when you tilt it. Place the pan upside down on a center rack and bake it for an hour. Then, turn off the oven and let the skillet cool naturally. If you missed a spot, just repeat the oiling, baking, and cooling until you're happy with the result.
If you want to avoid using soap on your cast iron pan, you can simply wipe your pan clean after cooking instead of exposing the pan to water and harsh scrub brushes. Alternatively, oil and kosher salt are more effective than soap and a sponge. Pour a few tablespoons of each into the still-warm skillet and scrub the pan with a paper towel until the pan is shiny and the salt is near black. Rinse out the salt and thoroughly dry the pan. You can rub it with a touch more oil before storing, if desired.
