I'd say soak them overnight in fresh water, then rinse well under a tap. That should take the salt off.

Subject: [CONCH-L] Washing seashells
Can I ask the professionals (for example Paul Callomon), what they consider to be a suitable length of time to wash or soak beach-collected empty marine mollusk shells with freshwater, in order to remove the salt?
Thanks.
