A cast iron skillet can last for generations if it’s cared for properly. Unlike regular nonstick pans, cast iron develops a natural seasoning over time that improves flavor, cooking performance, and durability. But many people still feel unsure about the correct cleaning process.
If you’ve ever wondered how to clean a cast iron skillet, you’re not alone. There’s a lot of conflicting advice online about soap, rust, burnt food, and seasoning. The good news is that maintaining cast iron is much simpler than it seems once you understand the basics.
