[meteorite-list] cleaning Millbillillie ?

[Matthias Bärmann]

Hello Alex,

I completely agree with you. To continue with Australia'a laterite-red: 
would anyone like to clean this Henbury iron on
Dr. Svend Buhl's website?

Can't imagine. In any case, I wouldn't. Its time on the surface of our 
planet is definitely part of a
meteorite's destiny.

My best, Matthias
