Cast iron pots are a timeless culinary essential, renowned for their durability and exceptional heat retention. However, even the most seasoned cook can encounter the unfortunate mishap of burning food within their beloved cast iron. The resulting crusty, blackened residue can be daunting to remove, but fret not! With the right techniques and a touch of elbow grease, you can restore your cast iron pot to its former glory. In this comprehensive guide, we will delve into the simple yet effective methods for cleaning burnt cast iron pots, ensuring their longevity and continued culinary prowess.
Contrary to popular belief, soap is not recommended for cleaning cast iron pots as it can strip away the protective seasoning that prevents rust and enhances cooking performance. Instead, opt for a natural abrasive such as salt or baking soda. Generously sprinkle your chosen abrasive over the burnt areas and let it sit for 15-20 minutes. The abrasiveness of these ingredients will gently lift away the charred food particles without damaging the delicate seasoning. Once the residue has softened, use a sturdy brush or sponge to gently scrub away the loosened debris, revealing the clean surface beneath.
For particularly stubborn burnt-on food, enlist the power of heat. Place your cast iron pot over medium heat and allow it to warm up. As the pot heats, the burnt particles will loosen and become easier to remove. Using a metal spatula or wooden spoon, carefully scrape away the softened residue. Be cautious not to apply too much pressure, as this could potentially damage the seasoning. Once the majority of the burnt food has been removed, proceed with the abrasive cleaning method described above to ensure a thorough cleaning. With a little patience and the right techniques, your cast iron pot will be restored to its pristine condition, ready to embark on countless future culinary adventures.
Using Hot Water and a Sponge
Filling the Pot with Hot Water
Begin by filling the burnt cast iron pot with hot water. The hotter the water, the more effective it will be at loosening the burnt-on food. Allow the water to sit in the pot for several minutes, giving it time to soften the residue.
Scrubbing with a Sponge
Once the burnt-on food has softened, use a sponge to gently scrub the surface of the pot. Avoid using abrasive sponges or brushes, as these can damage the seasoning of the cast iron. Focus on applying even pressure while scrubbing, working in small circular motions. If the burnt-on food is particularly stubborn, you can sprinkle a small amount of baking soda or salt onto the sponge to provide additional scrubbing power.
Rinsing and Drying
Once you have thoroughly scrubbed the pot, rinse it well with hot water to remove any remaining food particles or cleaning agents. Immediately dry the pot thoroughly with a clean towel to prevent rust from forming.

Employing Salt or Baking Soda
Salt
Salt is a common household item that can be used to clean a burnt cast iron pot. To do so, sprinkle a generous amount of salt over the burnt area and let it sit for several hours. The salt will draw out the moisture from the burnt food, making it easier to remove. Once the salt has sat for a while, use a stiff brush or a scrub pad to scrub away the burnt food. Rinse the pot thoroughly with hot water and dry it completely.
Baking Soda
Another effective way to clean a burnt cast iron pot is to use baking soda. To do so, make a paste by mixing baking soda with a small amount of water. Apply the paste to the burnt area and let it sit for several hours. The baking soda will help to neutralize the acids in the burnt food, making it easier to remove. Once the baking soda has sat for a while, use a stiff brush or a scrub pad to scrub away the burnt food. Rinse the pot thoroughly with hot water and dry it completely.
Vinegar
Vinegar is a natural acid that can help to dissolve burnt food. To clean a burnt cast iron pot with vinegar, fill the pot with a mixture of equal parts vinegar and water. Bring the mixture to a boil and let it simmer for 15 minutes. The vinegar will help to loosen the burnt food, making it easier to remove. Once the vinegar has simmered for a while, use a stiff brush or a scrub pad to scrub away the burnt food. Rinse the pot thoroughly with hot water and dry it completely.

Scrubbing Away the Burnt Residue
To begin, fill the burnt pot with a couple of inches of boiling water. This will help loosen the burnt-on food. Let it sit for a few minutes, then gently scrub with a nylon or plastic brush, avoiding metal scrubbers that can scratch the seasoning. If the residue persists, repeat the soaking and scrubbing process until it’s removed.
Neutralizing with Baking Soda
Next, make a paste by mixing equal parts baking soda and water. Apply this paste to the burnt areas and let it sit for 15-30 minutes. The baking soda’s alkaline properties will neutralize the acids in the burnt residue, making it easier to remove.
Removing Stubborn Residues with Salt
Dry Method
For particularly stubborn burnt-on food, sprinkle a generous amount of kosher salt over the affected areas. Scrub with a paper towel or clean cloth until the residue is removed. The salt’s abrasive nature will help physically break down the burnt-on food.
Wet Method
Alternatively, you can create a salt solution by mixing equal parts kosher salt and hot water. Pour the solution into the affected areas and let it sit for 15-30 minutes. The salt will dissolve and penetrate the burnt-on residue, making it easier to scrub away.
Seasoning after Cleaning
Once the burnt residue is removed, it’s essential to re-season the cast iron pot to protect it from further damage. Here’s how:
- Wash the pot with hot soapy water and dry it thoroughly.
- Apply a thin layer of oil (vegetable, canola, or grapeseed) to all surfaces of the pot, inside and out.
- Preheat the oven to 450°F (230°C).
- Place the oiled pot upside down on a baking sheet lined with parchment paper.
- Bake for 1 hour.
- Turn off the oven and let the pot cool completely inside.
