As a homeschool project with my 6 year old I decided to show him how cool it was to clean copper pennies by soaking them in vinegar and salt. He was appropriately impressed for about 12 seconds...then I got curious. Having a very weak chemistry background, I started wondering if the same process worked with metals other than copper.

I have a really cool meteorite pendant that I wear every day. I helps remind me that I am a part (literally) of the universe. It is not as shiny as it was when I first got it...so I thought I would put it in the same vinegar/salt bath that the pennies were in. Since most of you reading this know more about chemistry than I do - I am sure you know what happened. I copper plated my iron meteorite pendant. Talk about experiential education!

So...I learned something cool. But, now I want my groovy meteorite back to the silvery iron color it was before I messed with it. Other than through mechanical means (buffing it is tough because of all the little nooks and crannies), can anyone suggest a solution (no pun intended) to fix this?

What is the colour now? Black?

Sounds unlikely that you were able to dissolve enough copper from coins to copper plate iron. But assuming you did - what you have is so thin it will most likely wear off by itself in a few days.
