[meteorite-list] Rust Question about my stone meteorite. BKF is the best :)

[Meteorites USA]

Regardless of the smell, I think this might just work well on unwa 
material. I'd still be hesitant to try it on rare types until I knew 
more about it. I have a few meteorites I'd like to use this on. Maybe 
when I get some time I'll try a few experiments. Thanks for the info Shawn.

As for staining and residue I see non. However, I did weigh the meteorite and before I did this process it weighed 3.48g and now it weighs 3.43g. So if you have a small fragment this process could make your 1g rare meteorite a 1 gram lesser meteorite and take it out of the 1 gram and over bracket. But for what I did, the results are fantastic and losing 50mg of the meteorite was worth it, and I think the 50mg was the rust, so it was a win win situation.

The meteorite looks so much better. I can see the true color of the meteorite, I can see the texture and the gray matrix. I have a link down below of before and after images of the meteorite :) Take a look and you will be amazed of the results.
