I just bought an Atomic Z2, and I'd like to know the proper way to clean it. I've read various stories (on here and otherwise) about not dunking atomic regs because of the seat-saving technology that could let water in. However, the owner of the LDS I bought it from (who rents Atomic regs and claims to use one himself) said not to worry about that and there's no problem dunking or soaking it. So, how should I clean it? (since I assume it should be cleaned in some manner)
