I recently got a Dakine Apex hydration pack for when i go on hols to Greece. I've never had one before and was just wondering if you need to do anything before using it. It came with no instructions but had a cleaning tablet in one of the pockets. Are you meant to use this first before using it?

Also what are the general rules of keeping these things clean and germ free?

Cheers for any help...[8D]
