Your pan isn't ruined. With some white vinegar and some care it can be as good as new.
Rust and Cookware don't go together well. And so it's totally normal to panic when you first see some appearing on your Carbon Steel Pan.
But don't worry, removing a rust stain from a Carbon Steel Pan is easy, and it'll perform just as well (if not better) after you've removed the rust.
It does takes a little more than dish soap and a sponge to clean rust, But, with a few tips you'll soon be able to not only clean rust, but prevent it from forming ever again. Here's how to get your Carbon Steel Cookware looking brand new.
Unlike Stainless Steel Cookware, Carbon Steel may rust when left in a moist environment for an extended period of time. This happens due to the presence of oxidizable iron in carbon steel’s alloy (which is what also causes Cast Iron to rust).
The good news is that most Carbon Steel pan owners will only have to worry about their cookware rusting after it’s been exposed to water for an extended period of time (like after letting it soak in the sink, which we don't recommend). Extensive rust most commonly occurs after a cleaning.
To prevent stubborn rust, we strongly advise doing the following after every cleaning that incorporates water:
A protective coating of oil can make all the difference when it comes to preventing stubborn rust.
If you live in a particularly humid area, or are using your Carbon Steel pan outdoors, there's an additional risk of your pan rusting due to the added moisture in the air. If this applies to you, you’ll need to take some extra precautions to shield your pan from environmental moisture and rust—like seasoning the exterior of your pan to decrease the amount of surface iron.
Already have a rusted area on your pan? Don't panic yet—let’s get into how to remove it with just a little effort and elbow grease.
There are a number of ways to remove rust from your Carbon Steel pan. Below are three of the most popular methods—follow along with our video or read on for step by step tips.The Salt Scrub Method
The least invasive rust removal method, this process uses coarse salt and oil to scour surface rust off of a pan.
This method is most commonly used for a small to medium sized rust spot, but it also works on larger rust areas as well.
This method involves using a coarse scrubber such as a scouring pad, steel wool, an abrasive sponge, or fine grit sandpaper to forcibly remove rust from your pan’s surface.
This is an effective method for removing rust from anywhere on the pan, including the bottom of the pan—which can sneakily develop rust without you realizing it.
Once you have scrubbed and rinsed your pan, be sure to fully dry your pan with a dry cloth before storing it for your next meal.The Vinegar Method
For interior heavy rust that just won’t go away, this method should do the trick and help prevent rust from developing in the future. Note that a reseasoning is required after this method, as the acidity of the vinegar will strip away your pan’s built up seasoning.
Because removing heavy rust from carbon steel also results in the removal of some or all of your pan’s built up seasoning, it’s important to season the pan again afterwards. This ensures the surface of your pan builds up a non stick coating, or patina, over time. Made In offers Carbon Steel Seasoning Wax that is great as a seasoning starter to begin building up that patina.
