Great post and pics. Not trying to add a sales pitch here, but if you bring them to me we stick the claws (which don't have to be cleaned off real well) in with our dermestid beetle colony and they clean EVERYTHING off down to the last stitch of tissue, leaving only the claw and nail pedicle. They do and awesome job and it only takes about 2 days to complete a full set of claws.
