Light rust scrubs off with steel wool + dish soap in 10 minutes. Heavy rust needs a 50/50 vinegar-water soak (1-8 hours), then steel wool scrub, then immediate re-seasoning. The trick: don't leave a rust-removed pan unseasoned for more than an hour or it'll rust again.

What to Look For
Vinegar soak for heavy rust. A 50/50 white vinegar and water bath dissolves rust chemically. Start at 1 hour, check, repeat. Don't exceed 8 hours total — vinegar starts eating the cast iron itself once the rust is gone.
Re-season IMMEDIATELY. Stripped cast iron rusts within hours of being dried — exposed iron + air + humidity. Always rinse, dry thoroughly on a hot burner, and apply seasoning oil within the hour.

Frequently Asked Questions
Does vinegar damage cast iron?
Vinegar damages cast iron if left longer than 8 hours — it removes rust but also etches the iron itself once the rust is gone. Check the pan every hour and pull it as soon as the rust wipes off.
Can I save a badly rusted cast iron pan?
Yes — vintage Wagner and Griswold pans are routinely restored from 50+ years of rust. The iron underneath survives almost anything. Vinegar bath + steel wool + re-seasoning works on even orange-coated pans.
What's the best product to fix this?
We'd reach for the Brillo Steel Wool Soap Pads. Aggressive steel wool for stripping rust — the classic restoration tool.
How long does this take to fix?
Most solutions are 10-30 minutes of active work. Prevention takes 30 seconds per use.
