#### Can You Put Cast Iron in the Dishwasher?
The short answer is **no**, you should not put cast iron in the dishwasher. But why? Cast iron’s unique properties and its seasoning—the protective layer of polymerized oil that gives it a nonstick surface—make it incompatible with the harsh conditions of a dishwasher.
According to Lodge Cast Iron, a leading manufacturer of cast iron cookware, “The dishwasher’s detergent and high heat can strip away the seasoning and leave your cast iron vulnerable to rust.” [(( Lodge Cast Iron ))] The combination of strong detergents, prolonged exposure to water, and the drying cycle’s heat can break down the seasoning and expose the raw iron underneath. Once that happens, rust can form quickly, undoing years of careful maintenance.
Even if your cast iron survives a dishwasher cycle without visible rust, the seasoning will likely be compromised. Over time, repeated dishwasher use could turn your prized pan into a pitted, sticky mess. Experts at Serious Eats echo this sentiment: “Dishwashers are a no-go for cast iron. The moisture and detergents are too aggressive for the material.” So, while it might be tempting to toss your skillet in with the rest of the dishes, it’s a risk not worth taking.

#### Why Cast Iron Requires Special Care
To understand why dishwashers and cast iron don’t mix, let’s dive into what makes cast iron unique. Unlike stainless steel or nonstick pans, cast iron isn’t coated with synthetic materials. Its nonstick quality comes from seasoning, a process where oil is baked into the surface to form a protective layer. This layer not only prevents food from sticking but also shields the iron from moisture, which causes rust.
The Kitchn explains it well: “Cast iron is porous, and the seasoning fills in those microscopic gaps. When you expose it to too much water or strip the seasoning, you’re inviting rust and ruining the pan’s performance.” [(( The Kitchn ))] Dishwashers exacerbate this by combining water, heat, and alkaline detergents—all enemies of seasoning.
Beyond rust, improper care can lead to a host of other issues: food sticking, uneven cooking, and even a metallic taste in your meals. Proper maintenance, on the other hand, enhances cast iron’s performance over time, making it a true heirloom piece.

#### Best Care Tips for Cast Iron Cookware
Now that we’ve established why dishwashers are off-limits, let’s explore how to care for your cast iron the right way. These tips are drawn from experts, manufacturers, and seasoned home cooks who’ve mastered the art of cast iron maintenance.
##### 1. Cleaning After Use
Cleaning cast iron doesn’t require fancy tools—just a little know-how. After cooking, let the pan cool slightly (but not completely, as warm cast iron is easier to clean). Here’s the process:
– **Scrape off food residue**: Use a wooden spoon, spatula, or a chainmail scrubber to remove stuck-on bits. Avoid steel wool unless absolutely necessary, as it can scratch the seasoning.
– **Wash with minimal soap**: Contrary to old myths, a small amount of mild dish soap won’t ruin your seasoning. Bon Appétit advises, “A drop of soap and a soft sponge are fine—just don’t soak it.” Rinse thoroughly with warm water.
– **Dry immediately**: Water is cast iron’s nemesis. Use a clean towel or place the pan on a low burner to evaporate all moisture.
##### 2. Re-Seasoning When Needed
If your cast iron looks dull, feels sticky, or starts to rust, it’s time to re-season. The process is simple and restores that glossy, nonstick finish:
– **Clean thoroughly**: Scrub off any rust or residue with coarse salt and a cloth.
– **Apply oil**: Rub a thin layer of neutral oil (like vegetable, canola, or flaxseed oil) over the entire surface—inside and out.
– **Bake it**: Place the pan upside down in an oven at 350–400°F (175–200°C) for an hour, with a baking sheet underneath to catch drips. Let it cool in the oven.
America’s Test Kitchen notes, “Seasoning isn’t a one-time thing—it’s an ongoing relationship with your pan.” [(( America’s Test Kitchen ))]
##### 3. Storing Cast Iron Properly
Storage plays a big role in preventing damage. Keep your cast iron in a dry place, and avoid stacking heavy items on top, which can scratch the seasoning. If stacking is unavoidable, place a paper towel or cloth between pans to protect the surface.
For long-term storage, Southern Living suggests, “A light coating of oil before storing can keep rust at bay, especially in humid climates.” This extra step is a small price to pay for longevity.
##### 4. Tackling Rust
If rust appears, don’t panic—it’s fixable. Scrub the affected area with a mixture of salt and vinegar or a rust eraser, then rinse and re-season. Prevention is better than cure, though, so always dry your cast iron thoroughly after cleaning.
##### 5. Cooking Tips to Maintain Seasoning
What you cook can affect your cast iron’s health. Avoid highly acidic foods (like tomato sauce) for long cooking times early in the pan’s life, as they can wear down new seasoning. Once the pan is well-seasoned, it can handle almost anything.

#### Bonus Tips and Common Misconceptions
Cast iron care is surrounded by myths, so let’s clear up a few:
– **Myth: Soap destroys seasoning.** Not true! Modern dish soaps are mild enough for occasional use. Just don’t soak the pan or use abrasive scrubbers.
– **Myth: You can’t cook delicate foods in cast iron.** With proper seasoning, cast iron excels at everything from pancakes to fish.
– **Bonus Tip: Use it often.** The more you cook with cast iron, the better the seasoning becomes. Oils from cooking naturally build up that protective layer.
Food & Wine sums it up nicely: “Cast iron thrives on use. It’s not meant to sit on a shelf collecting dust.” [(( Food & Wine ))]

#### FAQ: Common Questions About Cast Iron Care
**Q: What if I accidentally put my cast iron in the dishwasher?**
A: Dry it immediately and inspect for damage. If the seasoning is stripped or rust appears, scrub it down and re-season it following the steps above. It’s not the end of the world—just don’t make it a habit.
**Q: Can I use metal utensils with cast iron?**
A: Yes! A well-seasoned pan can handle metal spatulas or tongs without issue. Just avoid scraping too aggressively.
**Q: How often should I season my cast iron?**
A: It depends on use. If it’s sticky, dull, or rusted, re-season it. For regular maintenance, once every few months—or whenever it needs a refresh—works well.
**Q: Is pre-seasoned cast iron from the store good enough?**
A: Most pre-seasoned pans (like those from Lodge) are ready to use, but adding a few layers of your own seasoning can enhance performance and durability.
**Q: Why does my cast iron smell or smoke when I heat it?**
A: A faint smell or smoke is normal as leftover oils heat up. If it’s excessive, the pan might have too much oil residue—clean it and apply a thinner layer next time.
