Raw Steel Cookware & Rust: Why It Happens - And How to Fix It Easily at Home

Raw Steel Cookware & Rust
Raw steel (also known as carbon steel) cookware is loved for its durability, heat performance, and ability to build a natural non-stick surface. But one of the most common questions customers ask is: “Why does my raw steel pan have small rust spots?”
The good news is: Light rust on raw steel is completely normal - and very easy to fix.
This guide explains why it happens and the safest, most effective way to remove rust using the white vinegar method.
Why Raw Steel Can Develop Light Rust
Raw steel reacts naturally to moisture. Even though we’ve recently improved our packaging to make it more compact and protective, it’s still possible for tiny amounts of moisture or humidity to reach the pan during transit.
This can lead to:
- small orange dots
- light surface rust
- faint discolouration
These marks are purely cosmetic and do not indicate damage. They’re simply a natural reaction between raw steel and moisture - and they can be removed in minutes.
How to Remove Rust From a Raw Steel Pan (Proven White Vinegar Method)
This is a safe, reliable, widely recommended way to remove rust from carbon steel cookware. It works quickly and does not harm the steel.
What You Need
- White vinegar
- Firm sponge or scrub pad
- Warm water
- Clean cloth
- A little oil for re-seasoning or our Seasoning Wax!
Step 1 - Apply White Vinegar
Pour a small amount of white vinegar directly onto the rusty areas, or place a vinegar-soaked paper towel over the spot. White vinegar gently dissolves surface rust without damaging the steel.
Step 2 - Let It Sit for 10–15 Minutes
Allow the vinegar to work on the rust. This short window is all that’s needed to loosen the rust effectively.
Step 3 - Scrub the Area
Use a firm sponge or scrub pad to remove the rust. It should lift off easily once the vinegar has softened it.
Step 4 - Rinse and Dry Thoroughly
Rinse the pan with warm water and dry it completely. Ensuring the pan is fully dry helps prevent future rust.
Step 5 - Season Your Raw Steel Pan
Because vinegar removes a little surface protection along with the rust, finish by applying a thin layer of oil and heating the pan to begin building its seasoning. Raw steel pans arrive unseasoned, so this step is essential to protect the steel and create the natural non-stick layer they’re known for.
Once seasoned, your pan will look good as new and be fully ready to cook. To learn more about seasoning and caring for raw steel, see our full guide: Things You Need to Know Before Using Your Raw Steel Pan.
Is Light Rust Normal on Carbon Steel?
Yes - light rust is a completely normal part of owning raw steel cookware. Because carbon steel has no chemical coatings, it will react to moisture unless it has a strong seasoning layer.
The more you cook with your pan and maintain its seasoning, the more resistant it becomes over time.
Final Thoughts
If your raw steel pan arrives with small rust spots, don’t worry - it’s natural, normal, and incredibly easy to fix. A little white vinegar, a quick scrub, and a fresh seasoning will restore the steel in quickly.
With proper care, your raw steel pan will last a lifetime and continue to improve every time you use it.
