On that note:

I have tried all sorts of exotic anti-rusting methods but definitely the
best is :=20

Brush off all the rust with a wire brush, mix some methylated spirits
with Sodium Hydroxide (caustic soda) (about 3 Table spoons to 1 pint)
mix and soak the iron in it for at least a couple of weeks. Seems to
halt the oxidization nicely!=20

Smaller Irons respond better than very large ones, probably because it
takes time for the solution to penetrate.

Hi folks,
I've got a rusting Campo del Cielo iron meteorite here that originally=20
started off at 1050g but has been on the meteorite equivalent of the=20
Atkins diet so now weighs closer to 1 kilo. After a wire brushing it
still=20
looks OK but plan on giving this one some TLC (or sodium hydroxide) if=20
you want to arrest its condition and make it a fully-functioning member=20
of your collection. Please make me an offer. I'll return all replies.=20
Thanks for your intervention ;-)
