Hello Dave, All,
Most of the older Campos looked something like this when found:

http://www.meteorflash.com/Campo-del-Cielo.htm

-Even those pictured above have had most of the dirt and some of their
lighter-brown shale coats removed. You can see some remnants of it
left in the visible regmaglypts.

But...I wouldn't get a drop of water near any one of my meteorites if
it could be prevented. In my mind, that would be akin to acid-washing
a chipped tektite to hide the shiny chipped surface by giving it a
matte finish - apparently a common practice nowadays.

By doing so, you do, in a way, "fix" the chip. But the process also
changes/mars the surface of the entire tektite, altering it
irrevocably - kind of like forcing a meteorite to rust by soaking a
meteorite in water.

But your rust problems would only be beginning if you did that to a
meteorite - I think you'd be hard pressed to stop the rusting once you
got it started. You'd most likely have a horrible flaker on your
hands, even if you liked the way it looked.

I'd try trading your specimen for an uncleaned one - or buying one.
They're remarkably cheap, those Campos...

Regards,
Jason
