I was wondering how you guys take care of your diaphragm call? I thought I would place my diaphram call in a large prescription bottle with a mixture of Scope mouthwash and water to help keep it fresh and germ free. And actually I think Listerine would help keep the germs away even better. These calls can be a haven for germs, so I think sanitation is important. I dunno....what do you guys do?
