Why Salt is the Secret Ingredient for Cleaning Cast Iron

Let me be honest — when I first started cooking with cast iron in my early twenties, I had no idea how to clean it properly. I tried everything: dish soap, scrubbing pads, even letting it soak (which, in hindsight, was a terrible idea). Every attempt seemed to end the same way — rust, frustration, and a lot of confusion about why people were so obsessed with these heavy pans.

After ruining a couple of skillets and going through plenty of trial and error, I eventually landed on a simple, reliable solution: a salt-based cleaning method — refined over time into a salt and baking soda blend.

Why a Salt and Baking Soda Blend Works for Cast Iron

Salt is a proven, time-tested way to clean cast iron, but on its own it can be inconsistent depending on grind size and residue. By combining coarse salt with baking soda, you get a balanced, effective cleaner that lifts stuck-on food while staying gentle on seasoning.

Salt provides the abrasion needed to loosen cooked-on food, while baking soda helps break down grease and residue without scratching the surface. The result is a cleaner pan with less effort and no damage to the seasoning layer.

Unlike dish soap or harsh scrubbers, a salt and baking soda blend cleans cast iron without stripping or gouging the surface. It’s effective, predictable, and easy to use — especially for everyday cooking messes like eggs, meats, and sauces.

How to Clean Cast Iron with a Salt and Baking Soda Blend

This is the method we use and recommend at Skalecki’s Iron and Salt Co.:

Let the pan cool slightly so it’s safe to handle.
Sprinkle a small amount of the salt and baking soda blend into the pan.
Using a damp cloth, paper towel, or scrub pad, work the blend around in circular motions to loosen food and grease.
Wipe out the residue and discard the used cleaner.
Dry the pan completely, then apply a light coat of seasoning oil if needed.

No soaking. No harsh chemicals. Just a clean pan that’s ready for the next meal.

A Method Built on What Actually Works

Salt has been used to clean cast iron for generations because it works. Adding baking soda simply improves consistency and effectiveness without compromising the seasoning. It’s a straightforward approach that respects the material and keeps cast iron performing the way it should.

You don’t need a cabinet full of specialty cleaners — just a simple blend and a few minutes of care.
