Armor Care

With any metal armour most fine oils will do, but not heavy ones like engine oil. Olive and vegetable oil will eventually go rancid. Mineral oil is good and medieval. A three-in-one oil is fine. Wipe it off before use. Bicycle chain oil is my preference as it has a wax coating that polishes well on armour too. A couple of drops on the blade spread out with a small rag will give a thin coating and that is all you need, even for long term storage
