|It got into all the little porous holes as well, on this piece.|

This piece required more work, gross huh? This was in an apothecary jar and yes it is grey! I used the air and got off what I could which wasn't much, so I got out my multipurpose tooth brush and scrubbed it under some warm water, added a mild dish soap and began scrubbing. It looked a little better but not much. So I got out the bleach..... I mixed equal parts bleach and warm water, let it soak for a minute or two and scrubbed, let it soak a bit more and repeated a few times. This is how it turned out.
|It's white again! I don't know how good the bleach was for it, but word to the wise, don't let your coral get that dirty to begin with.|
I wanted to polish some of my shells also. You can do this with a soft cloth and Mineral Oil, and it will bring back the luster to a lot of them.
I would love to hear any ideas of suggestions you might have !
