Sword cleaning - mistakes to avoid

[Yvain]

@Interested Party, I don't think grade matters, as long as there isn't any additives in it, I've used sunflower seed oil successfully for cleaning!



Regarding horn, as @werecrow said, I also use neatsfoot oil. The collagen (not keratin, my bad!) will bind with it and strengthen it (it will not fix splits though, of course).
