Rust spots on gladius/best oil to use

[Crispvs]

I use a sanding sponge (presumably what you call a Scotch Bright pad) to clean my helmet, but then I spread pork fat very thinly over the helmet, which works extremely well, lasts for about three months, and is something the Romans could well have used themselves. The fat doesn't show, by the way, unless you look very closely. When the photo I have used for my 'avatar' was taken I had spread fat over my helmet only a few minutes before. I haven't tried it on my sword though. In any case, as my sword handle is made of bone I am a little wary of things which might discolour it past the natural discolouration one gets from regular use.
