We do work with a bryozoa called Bugula neritina. Its outer covering is basically limestone (with other cations, etc). When we retrieve from ocean - they are covered in algae.
What I've done is spray a little sugar water on them - and put in yard where we have ants - let the ants eat it - they do a good job of cleaning organics.
Not sure if you have any good bugs in Alaska??
A bit unorthodox but it works.

Subject: suggestions for cleaning algae off crab shells
I have a user that is interested in measuring Ca & Mg in crab larvae
shells using LA-ICP-MS. These guys are about 1 mm long, and some of
them have a lot of algae. Any suggestions on ways to clean the algae
off that would maintain the Ca & Mg levels in the shells?
