Stainless Steel chainmail scrubber – cast iron cleaner – $6 – Amazon

This and a silicon scrapper are pretty much what you need to clean cast iron or steel. It’s better than scrapping with my bamboo spatulas and knicking them. I think this is the lowest price so far based on search of forums. It hit frontpage at $7 last time. If anyone uses cast iron often this gets the bits stuck to it. Sometimes you can use this in combination with salt to clean it slightly better. But then you have to re oil the pan.
code at check out is SWUASXR3, but I also see it as a clickable offer on the amazon page.
