Easy way to make sure all the tubes get a good scrubbing
Doesn't do the work all by itself
Forgot about my camelbak 2L basic pack and found it growing something green and gross inside. Tossed some bleach in and used the scrubbing brushes to make sure I got every last bit of that mold out. Worked like a charm.
Obviously, the best option is making sure the mold NEVER grows, but if/when it does, or you decide to just give your hydration packs a good once over, these brushes really help.
