I discovered this neat trick an hour before setting off on a climbing holiday after finding that my CamelBak hose was disgustingly dirty.
Being loathe to spend £20 for a brush on a wire to clean the hose and without time to get one I looked around for something that could clean the hose.
Paracord was the answer! A loose knot in the end of a length of paracord, dropped through the hydration bladder's hose can be drawn through slowly and bring all the gunk with it.
Here's how I've done it ever since.

Signing UpStep 1: You will need....
- A dirty camelbak or other "hydration bladder" hose
- Milton tablets or other baby bottle sterilisation tablets. You could also use mild soapy water though not too much or you may leave a bad taste. Definitely don't use bleach.
- Paracord. About 10cm longer than the hose

Swished the tablets back and forth in the bladder until they dissolved. Let the mixture coat the entire inside of the bladder. Drain and then put in fresh tap water from the cold side about 2 cups worth again mixed with 1 tablespoon of lemon juice. Let soak for 30 minutes. Do not forget the drink tube and bite valve. This removes the nasties that grow inside your bladder.
Then just hang to dry.
you can also avoid introducing germs into your clean hose by swinging it to dry it inside instead of blowing thru it.
to clean the inside of hard to reach areas inside of your reservoir you can use dry rice with a little water and shake it to scour the inside. just wash it out afterward and get all the rice bits out. i use this trick with stainless steel bottles that have had coffee with cream in them. works better than a brush in some cases( specially with the narrow top bottles)
Good idea
