Hi everybody ! For all people trying to help me : thank you very much . Here are pictures of the 2 best shells I have to clean. The bleach (half bleach/half water) on Shell 2 didn't help ! What do you name "baby oil" ? Please tell me how to clean thes shells and if you have their names, I would appriciate. I remind to you that they are from Seychelles.
