Dear Pete Pete,
        Perhaps a few suggestions are in order here to be sure you are
eternally happy with you big Campo. They have water in them and until that
moisture is removed you will have corrosion, flaking exterior crust,
internal rust blooming to the surface. Read the November issue of
"Meteorite". This is what I do in my laboratory. The answer is in proper
processing in a vacuum. I'm ready to help you if you like. I'll be in
Tucson.

Greetings, List,
Some advice, please!

I have several Campo specimens, and all but two are very stable, even with
lots of handling.
Actually, the unstable ones are handled the least, due to their size.
Not severe, but a coating of rust, and some flecks coming off when handled.
The two oxidizing happen to be uncut.

All are stored in the same place.

Can I use a wire brush to clean them?

If so, what is the choice metal brush the pros use? Is a standard auto-body
brush harmless? I found out the hard way that using a brush of brass-wire
(on wrought iron) leaves a golden hue behind.

Cheers,
Pete
