The Cast Iron Mistakes: How To Destroy Your Pan In Five Easy Steps

Cast iron pans are a popular kitchen utensil, but they do require some special treatment to keep them in good condition. Cast iron skillets are tough but not indestructible, and there are several ways to ruin them. For example, cast iron pans should never be put in the dishwasher or left to soak in the sink, as this will cause rust. They should also be allowed to cool before being washed to avoid overheating or uneven heating, which can cause warping or cracking. Cast iron pans should also be dried thoroughly and wiped with a thin layer of oil to protect them from rust.

Leaving it to soak

Leaving a cast-iron pan to soak is a surefire way to ruin it. Cast iron is porous, and long exposure to water can cause it to soak up the moisture and eventually rust. While a short soak won't do much harm, it's best to avoid soaking cast iron for fear of forgetting it and ruining the cure.

If you do leave your cast-iron pan to soak and it develops rust, don't panic. You can head off rust by drying the pan thoroughly with a paper towel or a lint-free cloth and then rubbing in a light layer of cooking oil. If the rust doesn't come off with a quick rinse, steel wool should do the trick. Don't be afraid to really scrub, but know that you may need to season the pan again.

To avoid rusting, it's important to dry cast iron as soon as possible after washing. The best way to dry a cast-iron pan is to set it over a high flame for a few minutes. You can also dry the pan with a paper towel or dish towel, but make sure you use a dedicated dish towel, as cast iron will turn your best towels black.

In addition to avoiding soaking, there are a few other things to keep in mind to properly care for your cast iron. Firstly, never put cast iron in the dishwasher. The combination of harsh detergents, heat, and long stretches in a damp environment can destroy years' worth of seasoning in minutes. Secondly, don't let cooked-on food remain on your skillet. Seasoning is a micro-thin coating, and anything left on the pan that you can feel when you run your fingers over the surface is not seasoning but crud, which is not non-stick. Use a plastic scrubber or a chain mail pad to get rid of any bits of leftover food.

Putting it in the dishwasher

Putting your cast iron pan in the dishwasher is a surefire way to ruin it. The combination of harsh detergents, high temperatures, and long stretches in a damp environment can destroy years' worth of seasoning in minutes. Cast iron is particularly susceptible to damage from excess moisture, and the water jets and detergents in a dishwasher will strip away the seasoning on the pan.

The dishwasher's heat dry setting is also not sufficient to dry cast iron, as it tends to leave a lot of moisture behind. This can lead to rusting, which can be difficult to remove and may require you to re-season the pan.

If you do accidentally put your cast iron pan in the dishwasher, you can try to salvage it by removing the rust and re-seasoning the pan. To remove rust, you can use a vinegar/water soak, baking soda/water paste, or coarse salt to scrub the pan. After rinsing, washing, and drying the pan, you can re-season it by coating it with a thin layer of vegetable oil or shortening and placing it upside down in the oven at a low temperature for an hour or so.

To avoid ruining your cast iron pan, it's best to hand wash it with warm water and a mild dish soap, dry it thoroughly, and apply a thin layer of oil before storing it in a dry place.

Overheating it

Cast iron skillets are incredibly durable and can be used for a variety of cooking purposes. However, overheating them can cause irreversible damage.

Cast iron skillets are known for their ability to conduct heat exceptionally well. They can get hotter than other types of cookware, and their heat retention is one of their best features. However, this also means that they can easily get too hot for the dish you're trying to cook. It is best to start heating your cast iron skillet at a lower temperature than you might usually use, and then gradually increase the heat as you get to know your pan. Keep an eye out for warning signs of extreme heat, such as smoke.

If you stick your cast iron skillet into a roaring fire or on a high-heat burner, you risk overheating or unevenly heating it, which can cause permanent warping or even cracking. This is because cast iron is strong but brittle, like glass; it will break before it bends. Warping occurs when one region of the pan expands faster than the surrounding area due to extreme heat or rapid cooling, such as when a hot pan is immersed in cold water. This can cause an otherwise smooth and flat pan to become irrevocably concave or convex, resulting in uneven cooking as liquids and cooking fats pool in the centre of the warp or are dispersed to the pan's edges.

If you accidentally overheat your cast iron skillet, reduce the heat and allow it to cool to the proper temperature before adding your ingredients and continuing. Remember, cast iron skillets are tough, but they are not indestructible.

Dropping it

Dropping your cast iron pan can lead to a variety of issues that may ruin it. Here are some ways that dropping your cast iron pan can lead to its demise:

Cracks

Even a small crack in your cast iron pan can be a dealbreaker. When heated or cooled, the crack will expand and contract, and eventually, the pan will split. This can be dangerous if it happens while you're cooking. Cracks are also difficult to clean and can harbour bacteria and rust. Therefore, if you drop your cast iron pan and it cracks, it's best to discard it and invest in a new one.

Warping

Cast iron pans can warp when exposed to extremely high heat or rapid temperature changes. Dropping your pan may not directly cause warping, but if it lands on a hot surface or experiences a significant temperature change due to the impact, warping could occur. A warped pan will have an uneven base and may wobble when placed on a burner. While slight unevenness might not affect its performance significantly, a dramatic wobble will cause food to heat unevenly and may even cause it to spill or splash out of the pan. In such cases, it's best to retire the pan.

Holes

Creating a hole in cast iron is quite challenging, but it is possible if the pan is rusty and left untreated. Dropping your cast iron pan could contribute to this process if the impact damages the pan's finish and exposes it to moisture, initiating or accelerating rust formation. A hole in your cast iron pan is a sign that it's time to replace it.

Structural Damage

Dropping your cast iron pan from a significant height or onto a hard surface could result in severe structural damage. The pan may break into pieces or become severely deformed, rendering it unusable. In such cases, the only option is to discard the pan and purchase a new one.

To prevent these issues, always handle your cast iron pan with care and avoid dropping it. If you do accidentally drop your pan, inspect it carefully for any signs of damage and take appropriate action, such as reseasoning, repairing, or replacing the pan.

Not cleaning it

Not cleaning your cast iron pan can lead to a build-up of food residue, which can ruin the seasoning layer and make your pan sticky and less non-stick. This residue can be difficult to remove if left for too long, so it's important to clean your pan promptly after each use.

If you don't clean your cast iron pan, food particles and grease can become baked-on, making it even harder to clean. This can also lead to the formation of rust, which can be difficult to remove and can permanently damage your pan. Even if you manage to remove the rust, it will likely require re-seasoning, which can be a hassle.

Not cleaning your cast iron pan can also result in a build-up of bacteria, which can be harmful to your health. This is especially true if you're using your pan to cook meat or other perishable items. Regular cleaning with hot water and a mild detergent can help to prevent the growth of bacteria and ensure that your pan is safe to use.

In addition, not cleaning your cast iron pan can cause it to develop an unpleasant odour. This is because food particles and grease can become rancid over time, leading to a strong, unpleasant smell. This odour can be difficult to remove and may persist even after cleaning, requiring multiple rounds of cleaning and re-seasoning to fully eliminate.

Finally, not cleaning your cast iron pan can lead to a decrease in its overall lifespan. Cast iron pans are known for their durability, but proper care and maintenance are essential to ensuring their longevity. By not cleaning your pan, you're not only making it less effective in the short term but also potentially shortening its usable life.
