How often should I clean out my camelbak?

Question

I have a camelbak ambush that I use on a daily basis and I'd like to know how often I should clean it out.

Answer 1

If you can, dry it out after every use. If not run bleach through it every couple of days.

Answer 2

Hey, Mike! Haha, Mike the Bike. You should try to clean it out daily. I have a camelback that I try to keep clean, but it doesn't really work.  

Answer 3

I'd run a bit of bleach water through it every couple days just to be safe, particularly in this hot weather.

Answer 4

Daily if you can, especially if it is not filled with water.
