J. Carp Cleaning Kit for Universal Hydration Water Bladders, 4 in 1 Cleaner Set--Flexible Long Brush for Hose, Small Brush for Bite Valve, Big Brush for Bladder & Collapsible Hanger for Bladder Drying
I have been using a shish kabob stick with a papertowel rubberbanded on it to clean, and a folded wire hanger to expand it to dry. This is a HUGE improvement. Especially love the tube cleaning brush.
