When I worked in a steel mill, everybody snuck in grill grates and other dirty/rusty stuff and swished them in the acid rinse at an anneal line.That is such an easy restore. take some iron rod or other sacrificial piece of iron. Next fill a tub or bin with water and chuck some bicarb in and stir it a bit.
Take a battery charger connect the negative to the iron and the positive to the piece you want clean. If you don't want to make lots of connected sacrificial iron bits, you will need to turn the item being cleaned over now and again as it is a line of sight process... This will clean even rusted stuck shit. It will not touch a single healthy clean iron molecule on the piece being cleaned.
Leave the shit in there overnight. Tomorrow take a hard brush and some water and it will clean up to the bone.
Things like that were 7 seconds from shiny new. Kolene worked best.
