Chilblains
Pour kerosene oil in a saucer, wring out a rag in it and with this wipe the affected parts several times each day. If awake in the night, do the same thing. Do not saturate the cloth and lay it upon the chilblains, as it might cause a blister. Wipe the feet with a dampened cloth and let them dry themselves.

To Take Rust from Steel Implements or Knives
Rub them well with kerosene oil, leaving them covered with it a day or so; then rub them hard and well with finely powdered unslaked lime.
