[meteorite-list] Cleaning Campo del Cielos

[Pete Pete]

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
