Short soaks are fine, but long soaks can cause rusting
Cast iron skillets are a versatile tool for any home cook. They are unmatched when it comes to retaining heat, allowing for the perfect sear, and can last for decades. However, to access these benefits, cast iron pans need to be cleaned and maintained properly.
While short soaks are generally considered acceptable, it is important to avoid leaving your cast iron pan soaking in water for extended periods, especially overnight. Cast iron is a porous material, and prolonged exposure to water can cause it to absorb moisture, leading to rusting. This is why it is recommended to avoid soaking your cast iron pan and instead clean it promptly after use.
If you do find yourself needing to soak your cast iron pan, it is best to limit the soaking time to a minimum. A short soak won't cause any significant harm, but it's easy to forget about it and leave it for too long. Even if your pan is seasoned, it's best not to take the risk.
To effectively clean a cast iron pan without soaking, you can bring a few cups of water to a boil in the pan itself, which will loosen any stuck-on food residue. Then, dump the water, scrub the pan gently, and rinse it with warm water. This method ensures that your cast iron pan is cleaned thoroughly without the risk of prolonged exposure to water.
Additionally, always ensure your cast iron pan is completely dry before putting it away. Any residual water can also lead to rusting. A thin coating of vegetable oil or a paper towel lining can help keep your cast iron pan in optimal condition.

Leaving cast iron to soak is worse than using soap or cooking acidic food
If you do end up with a rusty cast iron pan due to prolonged soaking, it can be restored. You can use steel wool to scrape away the rust, then wash the pan with soap and warm water, and finally dry it thoroughly. However, it is best to avoid reaching this stage by preventing rust in the first place.
Instead of soaking, it is recommended to clean cast iron skillets immediately after use. Boiling water in the pan and using a spatula to scrape off any stuck-on food is an effective method. You can also use coarse kosher salt and a glug of oil to scrub off any remaining residue. After cleaning, it is important to dry the pan thoroughly and apply a light layer of oil to prevent rust and maintain the seasoning.
While some people believe that cooking acidic food in cast iron pans should be avoided, this is not necessarily true. In fact, regular use of cast iron cookware, including cooking acidic foods, can improve its performance over time. The more you cook with it, the better it becomes. The key is to season the pan properly after each use, creating a thin layer of polymerized oil that protects the skillet and makes it non-stick.
In summary, leaving cast iron to soak for extended periods, especially overnight, is worse than using soap or cooking acidic food. Soaking can lead to rust, which can be challenging to remove and can damage the pan. Proper cleaning, drying, and seasoning techniques are essential to maintaining the quality and longevity of cast iron cookware.

Cast iron skillets need to be cleaned and cared for differently from other pans
Cast iron skillets are a versatile tool for any home cook, whether used on the stove, in the oven, or over an open fire. They are unmatched when it comes to retaining heat, allowing for the perfect sear, and can last for decades. However, cast iron skillets need to be cleaned and cared for differently from other pans.
Cast iron is a porous material, and despite its durability, it can absorb water, which can lead to rusting. Soaking a cast iron skillet overnight is generally not recommended as it can cause rust. Short soaks are usually fine, but it is important to remember to dry the pan thoroughly afterward. If your cast iron skillet does develop rust, it can be restored. Remove the rust with steel wool, then wash the pan with soap and warm water before drying it thoroughly.
To clean a cast iron skillet, it is best to rinse it with water when it is still warm from cooking. If there are stuck-on pieces of food, bring a few cups of water to a boil in the pan, then scrub and rinse. You can also use a paste of coarse kosher salt and water to scrub off any extra stuck-on bits. Avoid using soap, as it can strip the seasoning and leave a soapy taste. Instead, a little kosher salt and a glug of oil can be effective in cleaning the pan.
Proper seasoning is key to maintaining a cast iron skillet. Seasoning creates a thin layer of polymerized oil that protects the skillet and creates a non-stick surface. To season a cast iron skillet, coat it with oil and bake at a high temperature for 1-2 hours. Repeat this process 2-3 times, allowing the pan to cool naturally each time. The more you cook with a cast iron skillet, the better it becomes, so regular use is recommended.
In summary, cast iron skillets require specific care, including avoiding prolonged soaking, proper cleaning without soap, and regular seasoning. With consistent care, cast iron skillets can last for decades and improve with age.

If seasoned correctly, cast iron should never need a soak
Cast iron skillets are a versatile tool for any home cook, whether used on the stove, in the oven, or over an open fire. They are unmatched when it comes to retaining heat and can last for decades, improving with age and use. However, to access these benefits, cast iron requires specific care.
Cast iron is a porous material, and long exposure to water can cause it to absorb moisture and eventually rust. Therefore, it is generally recommended to avoid soaking cast iron cookware for extended periods, especially overnight. Short soaks are typically fine and won't cause significant harm, but they may not be necessary if the pan is seasoned correctly.
Seasoning creates a thin layer of polymerized oil that protects the skillet and makes it naturally non-stick. Regular use, such as frequent frying, searing, and sautéing, helps build up this seasoning. The more you cook with it, the better. Cooking a variety of foods, such as bacon, burgers, pancakes, and eggs, contributes to a well-seasoned pan.
If your cast iron does need a good cleaning, there are alternatives to soaking. For stuck-on food, boil some water in the pan and use the warm water to help scrape off the mess. Then, clean, dry, and apply a light coating of vegetable oil or another neutral oil like canola before storing it in a cool, dry place. Avoid using soap, as it can strip the seasoning and leave a soapy taste. Instead, a little kosher salt and oil can be effective for scouring.

To avoid soaking, boil water in the pan and scrape off stuck-on food
If you have stuck-on food in your cast iron pan, you can avoid soaking it by following these steps:
Firstly, boil a small amount of water in the pan—just enough to loosen the stuck-on food. This process is called deglazing. You can also add a small amount of vinegar to the water. As soon as the food is removed from the pan, add the water and let it boil down quickly. This will create a gravy that you can use for your meal, and it will also make the food left in the pan easier to scrape off.
After boiling the water, turn off the heat and let the water sit in the pan for a few minutes to further loosen any remaining stuck-on food. Then, use a wooden or nylon spatula to scrape off the food. Be sure to dry the pan thoroughly after scraping. You can also use a scrubby sponge, a non-scratch sponge, or a non-abrasive scrubber to clean the pan. If you're using a scrubber, hold it with tongs for protection from the heat.
If there is still stuck-on food after boiling water and scraping, you can try adding a bit of oil and salt to the pan. The salt acts as a good abrasive, and the oil helps to soften the food and maintain the pan's seasoning. Wipe out any leftover salt with a rag or paper towel when you're done. This method works best when the pan is still slightly warm.
It's important to note that while boiling water is an effective way to remove stuck-on food, it can also remove the seasoning from your pan. This is because the boiling water causes the seasoning to release, resulting in patchy or uneven layers. Therefore, if your pan has a good amount of seasoning, you may not need to oil it after boiling water and scraping. However, if your pan is not yet well-seasoned, it's crucial to reseason it after cleaning to prevent rust and maintain its non-stick properties.
