Eradicate Fish Odor From Cast Iron: A Step-By-Step Guide

Cast iron pans are a kitchen staple, providing optimal heating and durability. However, one common issue with cast iron pans is their tendency to retain strong odours, especially after cooking fish. The porous surface of the pan allows smelly substances to seep in, resulting in a lingering fishy smell that can be challenging to remove. Fortunately, there are several effective methods to eliminate this unpleasant odour and restore your cast iron pan to its fresh and odour-free state.

Boil the pan in water

Boiling water in a cast-iron pan is an effective way to remove fish odours. This method works because heating the pan releases the fish odour, which is then absorbed by the water.

To boil your cast iron pan, fill a larger pan or skillet with water and place it on the stove. Once the water reaches a boil, carefully place the cast iron pan inside and let it sit for 15 to 20 minutes. Then, remove the pan, discard the water, and refill the larger pan with fresh water. Repeat this process as needed until the fish smell is completely gone.

Alternatively, you can boil water directly in the cast iron pan. Fill the pan halfway with water and place it on low heat. Bring the water to a boil and let it boil for 15 to 20 minutes. Then, carefully remove the pan from the heat, discard the water, and refill with fresh water. Repeat as necessary until the fish odour is eliminated.

While boiling the pan in water is an effective method, it may take multiple attempts to completely remove the fish smell. Additionally, this method may not be ideal for cleaning the exterior of the pan.

Use baking soda

If your cast iron pan has developed a fishy odour, it's time to turn to the humble baking soda for a thorough clean and deodorization. Here's a detailed guide on how to use baking soda to eliminate that stubborn fish smell:

Step 1: Create a Baking Soda Solution

Start by creating a solution that will work its magic on the odour. Combine one part baking soda with five parts water directly in your cast iron pan. Adjust the amount based on the size of your pan. For example, if you're using a cup of water, add two tablespoons of baking soda. Ensure you mix it well so that the baking soda fully dissolves in the water.

Step 2: Boil the Solution

Place your cast iron pan with the baking soda solution on an open flame or stovetop. Turn on the heat and let the solution come to a gentle boil. As the solution heats up, the pan will gradually expand. This expansion is crucial as it helps to release any fish oil or residue trapped within the porous surface of the cast iron. Continue boiling until most of the liquid has evaporated. Depending on the size of your pan and the intensity of the heat source, this process can take anywhere from 10 to 30 minutes.

Step 3: Absorption and Extraction

As the solution boils, the baking soda goes to work, absorbing the released fish oil and preventing it from leeching back into the pan. To ensure maximum odour elimination, remove the pan from the heat while there's still a small amount of the baking soda solution left at the bottom. This remaining solution will continue to work its magic, absorbing any lingering fishy residue.

Step 4: Overnight Soak

Let the pan with the remaining solution sit out on your countertop at room temperature overnight. This extended period allows the baking soda to fully extract any remaining residue, ensuring a thorough deodorization.

Step 5: Rinse and Wash

The next day, give your pan a good rinse with clean water. If there are any stubborn baking soda residues, use a mild dish soap and a soft sponge to gently wash the pan. Make sure to rinse again after washing with soap to ensure no soap residue remains.

Step 6: Dry and Season

After rinsing, thoroughly dry your cast iron pan. You can let it air dry or use a clean cloth or paper towel to speed up the process. Once dry, it's essential to season your pan before using it again. Seasoning helps to protect the pan, improve its non-stick properties, and ensure your food doesn't stick the next time you use it.

There you have it! A simple, yet effective way to remove fish smells from your cast iron pan using baking soda. This method is a great, natural alternative to harsh chemicals, and it's likely that you already have baking soda in your kitchen, making it a convenient and cost-effective solution.

Heat the pan in the oven

Heating your cast iron pan in the oven is an effective way to remove the fishy smell. This method is suitable for cast iron pans that are completely made of iron, with no plastic or rubber parts.

To start, set your oven to 350 degrees Fahrenheit. Place your cast iron pan upside down on the middle rack of the oven. Heating the pan upside down will help open up the iron pores and allow any fish oils to slip out and dry up in the hot environment. Leave the pan in the oven for 30 to 45 minutes.

After 45 minutes, carefully remove the pan from the oven using oven mitts and place it on a heat-resistant surface to cool. Check the pan for any remaining fishy odours. If the smell persists, return the pan to the oven and heat for another 30 minutes at 350 degrees Fahrenheit.

This method of heating the pan in the oven not only helps to expand the pores of the cast iron but also dries up and eliminates any existing fish oil residue. It is a simple and effective way to remove unwanted fish smells from your cast iron pan without the need for harsh chemicals or extensive scrubbing.

Use white vinegar

White vinegar is an excellent agent for absorbing smells. To use this method, prepare a solution of equal parts white vinegar and water in your cast iron pan. Place the pan on an open flame and bring the solution to a boil. Allow the solution to boil for 20 to 25 minutes, and then remove the pan from the stove.

Do not discard the remaining solution. Instead, leave it in the pan for 24 hours. The vinegar will continue to work on the odour during this time, eliminating it completely. After 24 hours, discard the solution and wash the pan thoroughly with cold water. You may use a mild soap if necessary. Dry the pan and season it before using it again.

This method is similar to using a baking soda solution to remove odours from cast iron pans. Both white vinegar and baking soda are excellent at absorbing fish oil residue.

It is worth noting that this method is not ideal for cleaning the outside of the pan. If you wish to clean the outside, you may want to try boiling the pan in water instead.

Use lemon juice

Lemon juice is an effective way to remove the fishy smell from your cast iron pan. The citric acid in lemon juice helps to clear the fish oil and its unpleasant smell.

Firstly, squeeze 2-4 lemons into the pan, depending on its size. Then, add an equal amount of water to the lemon juice to create a solution. Set the pan aside for about an hour. The citric acid in the lemon juice will absorb most of the fish residue during this time.

Next, place the pan on a burner or an open flame. Bring the solution to a boil and let it heat for a few minutes. The solution will neutralise any remaining fish residue, providing an in-depth clean.

Finally, remove the pan from the heat. Discard the remaining solution and wash your cast iron pan with cold water before cooking in it again.
