4 min read

Iron deficiency affects over two billion people worldwide, leading many to seek alternative iron sources like the Lucky Iron Fish. To maintain this tool and ensure its longevity, proper care, including applying oil, is crucial to prevent rust from forming.

Quick Summary

Protecting your iron fish from rust is vital for its effectiveness and lifespan. The best options are refined coconut oil or the manufacturer's special blend, applied after each wash and thorough drying. Regular oiling creates a protective barrier against moisture damage and rust.

Key Points

  • Essential for Rust Prevention: Oiling your iron fish after each use is vital to prevent rust from forming due to moisture.

  • Choose the Right Oil: Refined coconut oil, olive oil, or the official Lucky Iron Fish Protection Oil are the best choices for proper maintenance.

  • Dry Thoroughly: The most important step in preventing rust is to completely dry the iron fish with a towel immediately after washing.

  • Avoid Air Drying: Never let your iron fish air dry, as this is the primary cause of rust formation.

  • Apply a Thin Layer: Only a drop or two of oil is needed to create a protective barrier; excess oil can leave a sticky residue.

Why Your Iron Fish Needs Oil

An iron fish, like the popular Lucky Iron Fish, is a simple, reusable cooking tool designed to add a safe and natural amount of iron to food and water. Made from food-grade electrolytic iron, it works by releasing microscopic iron particles when boiled in slightly acidic liquid. While this process is beneficial, the raw iron is susceptible to rust, which can occur if the fish is left wet. Applying oil after cleaning creates a protective barrier that seals out moisture, preventing oxidation and preserving the tool for its full five-year lifespan.

The Best Oils for Your Iron Fish

Not all oils are created equal when it comes to maintaining your iron fish. The ideal oil should form a strong, protective layer without becoming sticky or blocking iron release during cooking. The Lucky Iron Fish brand recommends their own natural protection oil, but suitable alternatives are readily available.

  • Refined Coconut Oil: A top choice for many users, refined coconut oil is a vegan-friendly, all-natural option that creates a clean, non-sticky coating. It's the primary ingredient in the official brand oil, prized for its protective qualities and lack of strong odor or flavor.
  • Olive Oil: A small amount of olive oil is also an effective and easily accessible option for keeping your iron fish conditioned. Like with cast iron cookware, a thin layer can help protect the surface from rust.
  • Lucky Iron Fish Protection Oil: The manufacturer’s own blend, made with refined coconut and lemon oils, is specifically formulated for the product. It's designed to protect the iron without interfering with the proper release of iron particles.

How to Clean and Oil Your Iron Fish

Proper cleaning and oiling are essential to prevent rust and maintain your iron fish. Follow these steps after every use to keep it in prime condition.

  1. Remove and Rinse: Carefully remove the iron fish from your pot after boiling. Rinse it immediately under cool, running water to lower its temperature.
  2. Wash Thoroughly: Hand-wash the fish with dish soap and the scrubby side of a sponge to remove any residue or acidity. This is also the time to address any rust spots using lemon juice and a scrubby sponge.
  3. Dry Completely: Dry the iron fish immediately and thoroughly with a clean kitchen towel. It is critical not to let it air dry or sit wet, as this is when rust can form.
  4. Apply Oil: Apply a single drop or two of your chosen oil to the surface. Rub the oil evenly over the entire surface with your fingertips or a clean cloth.
  5. Store Properly: Place the oiled fish in its storage box or another dry location away from moisture. A bowl near the stove can also serve as a good visual reminder for its next use.

Understanding the Consequences of Neglecting to Oil

Neglecting to properly dry and oil your iron fish can lead to a build-up of rust. While harmless when ingested in small amounts, excessive rust can affect the taste of your food and indicate that the product is not being cared for properly. The presence of rust means the iron is oxidizing, and if left unchecked, can compromise the integrity and effectiveness of the tool over time. Regular cleaning and oiling are a simple routine that will save you from needing to perform more intensive rust removal, which involves scrubbing with lemon juice and vinegar.

Conclusion

Maintaining an iron fish is a straightforward process that hinges on two main steps: immediate and thorough drying, followed by a light application of a protective oil. Refined coconut oil and olive oil are both effective and accessible options for this purpose, providing a robust barrier against moisture. However, the manufacturer's own blend is specifically designed and tested to ensure it prolongs the life of the product without hindering its function. By consistently following this simple care routine after each use, you can ensure your iron fish remains a safe and reliable tool for boosting your iron intake for years to come.
