Reservoir cleaning prevents the mold, mildew, and bacterial growth that develops when moisture sits inside a bladder between rides. CamelBak designed this kit specifically for hydration system maintenance, including two nylon brushes: a wide reservoir brush that scrubs interior bladder surfaces and a narrow tube brush that reaches through the entire length of drinking tubes.

The reservoir brush uses stiff bristles arranged in a circular pattern that contacts bladder walls as you work the brush through the opening. This mechanical scrubbing removes the biofilm that plain water rinsing leaves behind, especially in corners where the bladder material folds or along welded seams where residue accumulates. The brush head is sized to fit through standard reservoir openings without requiring you to force it past the threads.

The tube brush handles the interior surface of drinking tubes, which develops buildup faster than bladders because saliva enters the system each time you drink. The long, thin brush shaft reaches from one end of the tube to the other, with bristles that flex against tube walls to dislodge residue. You push the brush through from the reservoir connection end and work it back and forth several times until water runs clear when you rinse.... Read More
