Rose bengal is a water soluble biological stain. It probably binds to
proteins & other biological molecules. If it has bound to the protein in the
shell it may be not be possible to get it out without also damaging the
shell. Besides water, you may want to try the usual solvents, e.g., alcohol,
acetone, even a dilute base (for example, NaOH) solution.
