Hello Bob and list, I might be new to this, but I do know one thing! I
started out with a rather small collection that over this last year has not
grown much. It is still a small collection (30) with a lot of duplicate
meteorites. I kept my meteorites in a military ammo box with a big bag of
desiccant. I thought that would protect them well, well it did not! I kept
getting rust spots on my stones and irons.
With some advise from the list and some of my own ideas I do not worry
about rust any more, and will never will think about it again!
I now keep my meteorite collection in a 10 gallon fish tank (no water). I
have three large bags of desiccant on the bottom and covered them with
silver sand. Then, I have a little cartridge called Rust Inhibitor that fits
into a 12 gauge shot gun or can be hung in a gun safe with Velcro.I got it
at wal-mart for $4.00. I hade a piece of glass cut to fit the top of the
tank perfectly! I folded black type around the edge of the glass top and it
acts like a gasket to seal the tank (some what).
I have not had one problem with rust ever since! This will keep your
meteorites from rusting without coating them. Removing the rust in the first
place, I cant tell you. : ) TRY IT, YOU WILL LIKE IT!

P.S. My biggest is less than 200g's, I would do anything to have a 19 pound
iron! I am still trying to get a 500g meteorite for my collection. :
