Dear all, I need some help. I have a cowrie that smelled none too pleasant. First I sprayed it out with a pressure faucet. Then I put it in hygrogen peroxide overnight. Just a moment ago I took it out, and it was a bit messed up. It had sort of a haze over the right side of the dorsum that wasn't there before. I washed and scrubbed and washed and scrubbed, but it would not come off. What might have caused this and is there any way I can get it off? I would GREATLY appreciate any help. Thanks, James
