Cast iron pans are popular among cooks due to their durability and ability to develop a non-stick coating over time. However, one common question surrounding cast iron cookware is whether it is safe to soak the pans in water. While some sources advise against it, claiming that it will lead to rust, others argue that a short soak won't cause any harm. In this discussion, it is important to consider the porous nature of cast iron, which can absorb water and potentially cause rusting if not properly dried. Additionally, the use of soap and cleaning methods also play a role in maintaining the seasoning of the pan.

Cast iron pans are porous and can rust if soaked in water
Cast iron pans are durable, but they are porous and can absorb water. This means that if they are soaked or left in water for too long, they will absorb the moisture and eventually rust. Even a short soak can cause damage if the pan is forgotten and left in the water for too long. It is best to avoid soaking cast iron pans altogether and, instead, clean them with a small amount of warm water and a nylon brush or sponge. Pans should then be promptly dried with a paper towel or lint-free tea towel and stored only once they are completely dry.
If you do end up with a rusty cast iron pan, it is not the end of the world. Cast iron pans are resilient and can be restored. You can remove the rust by scrubbing it away with steel wool or a metal scrubber. You will also need to re-season the pan thoroughly. This can be done by coating the pan with oil and heating it in the oven at a low temperature for around an hour. Repeat this process two to three times, and your pan will be as good as new.
It is important to note that, while cast iron pans can be restored, it is best to avoid rust in the first place. Consistently caring for your pan by drying it thoroughly and regularly re-seasoning it will help to prevent rust and ensure that your pan lasts for years to come.
While cast iron pans are porous, this does not mean that they cannot be exposed to water at all. It is safe to rinse them with water and even boil water in them to help remove stuck-on food. Just be sure to dry them thoroughly afterward and avoid leaving them in water for prolonged periods.
In summary, cast iron pans are porous and can rust if soaked in water or not dried properly. However, with proper care and maintenance, they can last for many years.

Leaving a cast iron pan to soak is worse than using soap or tomato sauce
If you're going to use soap, it's best to avoid older varieties that contain lye, which will strip the seasoning and damage the pan. Modern dish soaps are much milder and won't affect the non-stick coating. After washing, be sure to dry your cast iron skillet completely to prevent rust.
If you're dealing with stuck-on food, it's better to fill the pan with hot water and let it sit for 5–10 minutes to loosen the residue. You can then use a brush or spatula to remove the mess, rinse the pan, and dry it on the stove. For extra tough residue, you can boil water in the pan and scrape while the water is still warm.
While cast iron pans are resilient and can withstand the occasional overnight soak, it's best to avoid making this a habit. Regularly soaking your pan will likely lead to rust and damage the non-stick coating you've worked so hard to build up. So, if you're looking to preserve your pan's seasoning and non-stick properties, it's best to avoid leaving it to soak for extended periods.

Soaking a cast iron pan can ruin the cure and non-stick coating
Cast iron is a porous material, which means that despite its durability, cast iron pans have the potential to absorb water, causing them to rust. Soaking a cast iron pan is, therefore, a surefire way to end up with a rusty skillet and can ruin the cure. While a short soak won't do much harm, it's best to avoid it for fear of forgetting and leaving the pan in water for too long. Instead, fill the pan with a few cups of water, bring it to a boil, and scrape off any stuck-on food with the help of warm water. Dump the water and clean, dry, oil, and store the pan as usual.
Leaving cast iron to soak in the sink is worse than cooking acidic food in it. Long exposure to water can cause the pan to soak up moisture and eventually rust. It is also likely to ruin any seasoning on the pan and the non-stick coating that has built up over time.
If your cast iron pan does develop rust, it doesn't mean you need to throw it away. Cast iron is resilient and long-lasting, and its ability to be restored is part of what makes it so durable. You can revive a rusty skillet by scrubbing away the rust with steel wool and reseasoning the pan.
To maintain the cure and non-stick coating of a cast iron pan, it's important to clean, wash, and dry the pan promptly after use. While today's mild dish soaps are safe to use on cast iron, it's best to avoid leaving soap or water sitting in the pan, as this can lead to rusting. Instead, use a small amount of soap, clean the pan with a nylon brush or sponge, and be sure to thoroughly dry the pan with a paper towel or lint-free tea towel before storing it away.

Cast iron pans can be cleaned with hot water and soap, then reseasoned
While cast iron pans are resilient, it is not advisable to leave them soaking in water, as this can cause rust. Cast iron is a porous material, and long exposure to water can cause it to absorb moisture and eventually rust. Therefore, it is recommended to avoid leaving cast iron pans in water and to dry them thoroughly after washing.
However, this does not mean that you cannot use soap and water to clean your cast iron pan. Today's dish soaps are mild and will not strip the seasoning or damage the pan. Here is a step-by-step guide to cleaning your cast iron pan with hot water and soap:
- Allow the pan to cool down mostly.
- Use a pan scraper to remove any stuck-on food and debris.
- Pour a small amount of soap into the pan, along with a small amount of warm water.
- Use a nylon brush or sponge to clean the pan, inside and out.
- Dry the pan promptly with a paper towel or a lint-free tea towel.
- Put the pan back on the stove and turn the heat to medium for about three to five minutes to ensure it is completely dry.
- Let the pan cool down completely.
- Apply a light layer of cooking oil, such as flaxseed, canola, or vegetable oil, to the surface of the skillet.
- Wipe out any excess oil and store the pan until you are ready to use it again.
It is important to note that you should always dry your cast iron skillet completely after washing to prevent rust. Additionally, make sure to re-season your pan after cleaning to maintain its non-stick properties.
If your cast iron pan does develop rust, you can restore it by scrubbing away the rust with steel wool or kosher salt and reseasoning it. Regular use and seasoning of your cast iron pan will create a thin layer of polymerized oil that protects the skillet and makes it non-stick.

Cast iron pans should be dried thoroughly after washing to prevent rust
Cast iron pans are durable and long-lasting, but they do require special care to prevent rust. Cast iron is a porous material, meaning it can absorb water, which can lead to rusting. While a short soak may not cause immediate harm, it is generally recommended to avoid soaking cast iron pans for extended periods.
Leaving a cast iron pan to soak overnight is likely to result in rust. Even a small amount of residual water left in the pan can cause rust to form. Therefore, it is crucial to dry the pan thoroughly after washing. This can be done by placing the pan back on the stove over medium heat for a few minutes to ensure complete evaporation of any moisture.
Properly drying and seasoning your cast iron pan will help prevent rust and maintain its non-stick properties. After heating the pan, let it cool completely, then rub a light layer of cooking oil on the surface. Oils such as flaxseed, canola, or vegetable oil are suitable for this purpose. Wipe out any excess oil and store the pan until its next use.
If your cast iron pan does develop rust, it can be restored. Use steel wool or a metal scrubber to remove the rust, then season the pan thoroughly. Building up a good seasoning on your pan will make it more resistant to rust and improve its non-stick qualities.
While cast iron pans require specific care, it's important to note that they can be washed with mild soap and water. Today's dish soaps are mild enough that they won't strip the seasoning from your pan. However, it's best to avoid aerosol oven cleaners, which can damage the pan's seasoning and iron. With proper care and maintenance, your cast iron pan will last for years and improve with use.
