Lars, I am not sure how Eric cleaned these.
I do know that soaking certain stone meteorites in acid (navel jelly) beautifully cleans the meteorite and removes dark rust stains. I have had great success with zag and juancheng as well as others. After a navel jelly soak of an hour they were totally different and really showed the chondrules and brecciation. I have cleaned pieces over two years ago and they remain beautiful and stable. Some meteorites which I have tried to clean did not change at all. Of course, when you subject these stones to navel jelly you are taking a risk of totally ruining them. I have never ruined a meteorite but had to put that caveat in there in case someone does.

How is this done ? And the brown color usualy covering the faces of many meteorite-slices, is that a result of oxidation from the atmosphere on this planet ? (rust?)
