Aluminium foil can do wonders for dirty or rusty cast-iron cookware.  

We debunked the myth of forgoing soap and water when cleaning your cast-iron pan long ago, but sometimes it just isn’t enough to remove stuck-on food. Restoring your cast-iron pan to its original glory takes some dedication, and these babies are notorious for being finicky. But all is not lost!

Lifehacker recently shared their hack for getting stubborn food or rust off your favorite cast-iron pan—a ball of aluminium foil. According to their article, scraping the inside of your pan with little hot water and wadded-up foil will be enough to remove stuck-on food without destroying your seasoning efforts.

However, as with any cast-iron pan, it still needs to be dried completely after washing to prevent rust. The pan then needs to finish drying on a burner turned to medium-low heat, and sprayed with cooking spray or doused with a few drops of cooking oil before letting it cool and rubbing the inside clean.
