my statements exactly.

my camelbak has been through hell and back, its standard Issue but I have used it on the bike.

in my experience, water only in them unless you have different bladders for each drink.

before I use it I empty the water that's been sitting in it for the past month (in the garage no less) run hot soapy water thru it and the tube, fill her up and that's that...no plastic taste unless the bladder is brand new.

I've used it for 2-3 months at a time just w/o cleaning it, just filling it up with water multiple times a day.
