If possible, place the article in a bowl containing kerosene oil, or
wrap the steel up in a soft cloth well saturated with kerosene; let it
remain twenty-four hours or longer, then scour the rusty spots with
brick dust; if badly rusted, use salt wet with hot vinegar; after
scouring rinse every particle of brick dust or salt off with boiling
hot water; dry thoroughly with flannel cloths and place near the fire
to make sure, then polish off with a clean flannel cloth and a little
sweet oil.
