Dear Mathew
I've found using a 0.05% solution of Phenol in seawater is usefull
for removing spionids from oyster shells if left overnight. See:
Dorsett, D. A. (1961). The reproduction and maintenance of
Polydora ciliata (Johnst.) at Whitestable. Journal of the Marine
Biological Association of the United Kingdom 41: 383-396.
Addition of O-dichlorobenzene can speed extraction up but is very
toxic! See: MacKenzie, C. L. and L. W. Shearer (1959).
Chemical control of Polydora websteri and other annelids
inhabiting oyster shells. Proceedings - National Shellfisheries
Association 50: 105-111.
Regards... Sean
