Tips

  • If you find the rust removal satisfying, give it a thumbs up!
  • Don't use soap on your seasoned cast iron pan.

Common Mistakes to Avoid

1. Using Soap

Reason: Many believe soap is necessary for cleaning, but it can strip the seasoning, leaving the pan sticky and prone to rust.
Solution: Use hot water and a stiff brush or chainmail scrubber, followed by thorough drying.

2. Overheating an Empty Pan

Reason: Heating an empty cast iron skillet to high temperatures can warp the pan and damage the seasoning, leading to sticking and uneven cooking.
Solution: Always add oil or fat to the pan before heating, even if you're just seasoning it.

3. Ignoring Rust

Reason: Rust indicates a lack of proper seasoning and maintenance, leading to further deterioration of the pan's surface.
Solution: Remove rust with a wire brush and re-season the pan thoroughly.

FAQs

Can I use soap on my cast iron skillet?
While harsh detergents should be avoided, a little mild dish soap is okay for cleaning your cast iron *after* it's well-seasoned. Focus on scrubbing with a good brush or chainmail scrubber, then thoroughly rinse and dry immediately. Avoid soaking for extended periods.
My cast iron is rusty. Is it beyond repair?
Not necessarily! Rust is often superficial. You can usually remove light rust using steel wool, a wire brush, or even a good scrubbing with coarse salt and oil. For heavier rust, a more involved cleaning process may be needed, as detailed in this guide, but don't give up hope!
