[meteorite-list] Cleaning a heavy iron meteorite

[Guenther]

Hi all,

A year ago I found a large heavy iron meteorite. When I found it the color
was a dark brown. In my attempt to bring out the true color, I decided to
use a dremel tool with a fine wire brush bit to clean it. The dremel brush I
used was extremely soft and gold in color and it turned slightly gold in
color. So, I bought a soft stainless steel wire brush and now it turns grey
when I brush it. What is the best way for me to clean it to get the true
color?

Here are the original images after I used the gold color brush:
