Go to the baby section at the local supermarket and get yourself a bottle of Miltons sterilization liquid.
Cleans it all out ready to roll again
as above or use the tablets
I use a hydration pack for mountain biking
The first one i bought was a cheapo and i could never get rid of the plastic taste then i spent the dough and bought a camel pak it was so much better.
dont leave it full of water for to long as mould will grow in it
