Tired of that annoying mould buildup that sometimes appears in the line of your Camelback Water System? Or any sports water storage system for that matter.
Well you can either use the high performance, and $40CAD, cleaning kit...

Or!!!!!!!!!!!
You can do this!
Take the slimmist coat hanger you can find, and straighten it out most of the way. Then tear off 1 inch of a jcloth, or similar thin cloth. With a pair of pliers, put a small (1/4inch) hook on one end of the coat hanger. This will be used to pull the cloth through the hose.

Then, remove the drinking hose from the water bladder, and the mouthpiece.

Then insert the coat hanger all the way through the hose with the hook out the other end.


Then hook the jcloth in the center with the coat hanger.

Then drag the cloth through the hose. You may have to do this several times to ensure you get all the gunk out of the hose. You can stop pulling, and do a little push in the area where the large deposits are, but be carefull to not disengage the cloth from the hanger. It would be a pain to get it out afterwards.
Luck.
