So a few months ago i asked for tips about rust removal, here and also to some meteorite friends, and got a lot of useful tips!  I promised to post a few pics after I worked on some meteorites, so here are some before and after pics, including one I did this week (Taza).  There was some trial and error but I feel comfortable with removing rust now... essential skill!!

Glad to be of service. I like the Agoudal, I have a few small ones, but I've never cut any. Something to think about!

Ya!  I admit that I have a fairly large collection of cut and etched Agoudal.  Love them.  (here we see work I force some of my students to do... hahaha)

For the ones in this thread, I used alcohol, vinegar, and ballistol.  If I were doing it again now, I’d use alcohol, CLR rust remover, and ballistol.  In any event most or all the meteorites above are still rust free.  smile.gif

Thanks for posting. I have a couple that need de-rusting after I moved to a much more humid location. I’m afraid all my irons and palacites will need sealing to survive this environment.

Cool.  I also live in a humid location so I hear you.

 

As you probably know, it's time consuming to individually box each iron, and then renew the desiccant every few months.  On the other hand keeping them together in a tupperware container with desiccant means you cant see them without removing the cover, and placement of the space rocks and desiccant can be awkward.  FWIW I found a good solution to this (not my idea, it was posted on another website)...... this guy.  It's great... the desiccant lies flat at the bottom under a screen, and the irons are visible when the cover is on and easily accessible when the cover is off.  Here's what some of my (mostly) irons look like in the container.

This thread is _extremely_ helpful. I have a tiny collection, but they're all irons: a fleck of Canyon Diablo from the Meteor Crater gift shop given to me by a friend, a piece of Campo I picked up at an auction years ago, and a beautiful (to me anyway) Sikhote-Alin shrapnel piece that I bought at RTMC a couple of years ago. I've always had the Sikhote-Alin out on the mantel and just today I noticed some brownish spots that I assume are rust. It came to me clean but I've never cleaned it or treated it with anything. Looks like it's time!

 

mark8888, the little display cases you showed above are very cool. I assume that's ethofoam over a layer of dessicant? If you have sources for the materials, I'd love to follow in your footsteps. Thanks in advance for any info.

Awesome!  I'm really glad the thread is helpful.

 

I'm not sure if it's exactly ethofoam, but it's most definitely dessicant.  Anyway, I buy both from Mirko.  These materials are available from many sources but quality can vary, I know I'm getting good stuff from him and he's very good with communication.
