I have been wanting to make this post for a while, but haven't gotten around to actually getting good pics until today. I have got myself one of the better Platystrophia brachiopods from my Nashville trip in August. It has a good bit of gunk stuck in the radial ribs, and I would at least like to clear a good bit of it out. Any cost effective tips?
