The question "How do you remove cast from iron?" is ambiguous, so this answer will assume you meant "How do you remove rust from cast iron?". Here's how to tackle rust removal from cast iron, with a focus on mild rust:
Removing Mild Rust from Cast Iron
If your cast iron has only light rust, you can often remove it with simple methods. Here's a breakdown using an abrasive method:
Using Baking Soda
One effective method for tackling mild rust involves using baking soda. Here's the process:
- Create a Paste: Sprinkle baking soda directly onto the rusted area, add a bit of water, and stir to form a thick paste. The paste should be rough and slightly gritty.
- Scrub the Rust: Use a rag, sponge, or soft brush to scrub the baking soda paste into the rusty spots. The baking soda acts as a mild abrasive, helping to lift the rust away.
- Rinse and Dry: After scrubbing, rinse the cast iron thoroughly with water and dry it completely.

After Rust Removal
After removing the rust, you'll want to maintain your cast iron to prevent future issues:
- Seasoning: After washing and drying your cast iron pan, immediately apply a thin layer of oil (like vegetable or canola oil) and place it in the oven at a high temperature to re-season the pan. This creates a protective layer that helps prevent rust.
- Proper Storage: Always ensure your cast iron is completely dry before storing it.
