How to Clean a Dutch Oven: Raw and Enameled Cast Iron

If you want your cast-iron or enameled Dutch oven to last a long time, it is important to learn how to clean a Dutch oven and maintain it properly.

Baking sourdough bread in a raw cast-iron Dutch oven requires little cleaning, whereas an enamel Dutch oven requires more.

How to clean a Dutch oven

A raw cast iron Dutch oven requires regular seasoning to keep its non-stick surface in good condition. This seasoning is a thin layer of oil baked onto the surface, helping prevent food from sticking and keeping the iron from rusting.

When cleaning, use mild dish soap and a soft brush or sponge to remove any food residue. After washing, dry the Dutch oven completely to prevent rust.

Even though some cast iron cookware is labeled dishwasher-safe, avoid putting it in the dishwasher. The harsh washing can damage the seasoning and wear down the finish.

If the seasoning seems worn or patchy, re-season it with cast iron seasoning oil and bake it until it shines.

Cleaning guide for raw Dutch oven

• Immediately after baking (or cooking), rinse the Dutch oven with warm water to loosen food particles. Avoid using cold water to prevent thermal shock.

• Try scrubbing stubborn spots with a paste made of baking soda and water.

• If needed, sprinkle kosher salt inside the pot and use it as a natural scrub with a soft sponge.

• Rinse thoroughly to remove all cleaning residue.

• To prevent rust, thoroughly dry the cast iron, preferably in a warm oven or on a stove.

How to re-season your cast iron Dutch oven

You should re-season the raw cast iron Dutch oven once or twice a year. Here is how to do it:

• Rub a thin, even layer of oil over the entire surface, inside and out. Use an oil with a high smoke point, like vegetable oil, canola oil, or melted shortening.

• Place the Dutch oven upside down in a preheated oven. Set the temperature to 375°F (191°C) or follow Lodge Cast Iron's recommendation of 450-500°F (232-260°C).

• Bake it for 1 hour, then let it cool before storing. This process creates a smooth, durable layer that protects the cast iron and keeps it non-stick.

How to take care of an enameled Dutch oven

An enameled Dutch oven differs slightly because its surface is coated with enamel. This makes cleaning easier and less prone to rust, but it needs gentle care to avoid chipping or cracking.

Here are a few simple maintenance tips:

• Wash the enameled Dutch oven by hand with warm, soapy water. Avoid using harsh scrubbers or abrasive cleaners because they can scratch the enamel.

• After washing, dry it thoroughly to prevent moisture damage.

• Don't preheat the empty enameled Dutch oven on high heat at 450-500°F (232-260°C). If needed, start with low heat and gradually increase to protect the enamel from cracking.

• Use wooden or silicone utensils to protect the enamel surface.

• When storing, place a soft cloth or paper towel between the lid and the pot to protect the edges from chipping.

How to clean an enameled Dutch oven

Sometimes, your enameled Dutch oven develops tough stains. Here are seven cleaning methods to try:

1. Using baking soda and water

Add 4 cups of water to the pot and bring it to a boil. Stir in 2 tablespoons of baking soda, then simmer for 8-10 minutes, scraping the bottom with a wooden spoon. Pour out the solution, rinse with warm water, and dry.

2. Using a non-abrasive cleanser

Use a paste made from a non-abrasive cleanser, like Bar Keepers Friend Powder, and let it sit for a few minutes before rinsing. For tough areas, let it sit for 20-30 minutes, then rinse.

3. Using baking soda and hydrogen peroxide

Pour about ½ inch of hydrogen peroxide into the pan, add ¼ cup of baking soda, and bring to a boil. When the mixture becomes foamy, turn off the heat and let it sit for 10 minutes. Discard the mixture and rinse with warm water.

4. Using white vinegar

Bring a 1:1 mixture of white vinegar and water to a boil in the pot. After boiling for a few minutes, let the mixture cool, then wash the pot with dish soap and a soft sponge. Finish by rinsing with warm water.

5. Using bleach and water

Soak the interior overnight in a mixture of one part bleach and three parts water. The next day, wash it thoroughly with soap and water. This method works for most stubborn stains.

6. Using lemon juice and salt

Cut a lemon in half, dip the cut side into coarse salt, and scrub the pan with it. Add 2 to 4 tablespoons of extra salt as needed. It is a quick, natural cleaning method, though not the most effective for tough residue.

7. Using toothpaste

Spread a thin layer of toothpaste over the bottom of the pan and let it dry for at least 2 hours (or overnight). Mist the surface with water, then scrub with a stiff-bristle brush or an old toothbrush. Rinse with soap and water.

This method is inexpensive (you likely already have toothpaste on hand), but it isn't the most effective for heavy buildup.

When to replace your Dutch oven

Dutch ovens are made to last for many years, especially if you take good care of them. However, there are times when you need to replace them.

If you notice cracks or chips in the enamel, it is time for a new one. These flaws can affect cooking and food safety.

Rust on raw cast iron Dutch ovens is a sign that they need to be replaced. Rust can change the flavor of food, including sourdough bread, and pose a health risk if consumed.
