If you can scrape some of it off, the best way to remove it, especially
down deep in grooves or pits in the sculpture, is an untrasonic cleaner. If
it is actual mineral staining, where iron or other substances in the
substrate has reacted with or replaced some of the calcium in the shell,
then an ultrosonic cleaner cannot remove it. But in that case you wouldn't
be able to scrape any of it off either. So what you describe sounds like a
good candidate for ultrasonic cleaning.  Ultrasonic cleaners are a bit
pricey, but every serious collector shoud have one. It's amazing the amount
of dirt the machine can remove, even from a shell you thought was already
clean.

  Does any one know how to clean off the mud stains that one often
encounters on the spires of some mud-dwelling species?  I have some Conus
phlogopus, Voluta virescens and Morum dennisoni that would look very nice,
but this blackish dirt fills in the hard-to-reach crevices of the apex.  I
can scrape some of it off, but was wondering if there was a better
technique...

  Any information on this would be greatly appreciated.
