I brought back a ton of shells from the beach. I soaked them in a bleach/water mixture for a few hours and then let them sit outside for a couple of days and they STILL smell! They don't smell as bad as they did when we got them but it's still bad!
I'm pretty positive there is nothing in them as most of the shells are bivalves.
Any suggestions??
Oh- and living them outside isn't really an option as I live in the city and am without my own yard.
