Rottie, I just wash them in fresh water and buff them up with my dremel if needed. Anything that is soak-in-bleach-stinky, like a crab claw, I just don't use. Be careful when you wrap, especially with the quartzy rocks - your tools can leave metallic marks that are really hard to get off.
Padfoot, do you live here? (Kure) I get most of my shells at Ft Fisher. And, what precisely are you doing with a picture of my boyfriend as your userpic??
No, I live near Raleigh. We went to Kure for a few days in August. We got a few shells at Fort Fisher too, it is such a beautiful place.
Do you mean the pic of my husband?
