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

[Shawn Alan]

Jim k and the List,
 
 
I took your advice and used the Bar Keeper Friend on my L6 meteorite fragment to remove the rust on the surface of the meteorite due to age and I would have to say, wow, this stuff really works. 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.

Hi Shawn, 

I doubt that soaking a meteorite in alcohol will remove rust. I've used 
fine grit sandpaper to remove rust from slices. Lay the sandpaper on a hard 
flat surface and gently rub the meteorite onto the sandpaper. For removing 
rust from iron etched slices, I use a product called "Bar Keepers Friend", 
this can be found in most grocery stores cleaning supplies isle. It comes in 
a powder form, so you have to make a thick liquid out of it. Wet the 
meteorite with warm water then apply the liquid BKF. Rub it onto the meteorite 
with your finger gently. Rubbing to hard can damage the etch. After removing 
the rust, rinse the piece, soak it in alcohol and bake it dry in an oven 
about 200 degrees for 2 hrs. 

You can try the BKF process on a chondrite fragment and use a toothbrush 
to scrub it. It should work but you might want to experiment with a cheap 
uncl. NWA first.

Hello Listers, 

I have a question about rust and how to clean it off your L6 meteorite. 
Now can you just soak the meteorite in a 99% alcohol bath for a couple days 
and the rust on the surface will some what come off the surface or are there 
other steps? 

The the size of the L6 fragment is 3.45g, so I dont have much room to work 
with. I used a sand/finger nail file and sanded the surface, but not sure 
if that made a difference and it seems that the L6 meteorite surface is 
stronger than the sand paper on the finger nail file. 

If any Listers have some suggestions let me know please :)
