Water bottles develop residue in places your hand can't reach. Electrolyte mix leaves a film on the bottom, mineral deposits build up around the threads, and the straw or bite valve accumulates gunk that affects taste even after you rinse the bottle. A sponge on a stick doesn't fit through narrow bottle openings, and dish soap alone won't scrub away buildup that's been sitting for weeks. This two-brush kit gives you the tools to actually clean a water bottle rather than just rinsing it and hoping for the best.

The large brush reaches the bottom of bottles and scrubs the interior walls where residue accumulates from sports drinks, coffee, or anything other than plain water. The bristles are stiff enough to remove dried-on buildup but won't scratch polycarbonate or stainless steel. The small brush handles straws, bite valves, and cap channels where mold grows in places you can't see. That narrow brush fits inside CamelBak's eddy straws, Podium valve assemblies, and the internal passages in tumbler lids where liquid flows through but your fingers don't fit.

The kit works with all CamelBak bottles, tumblers, and travel mugs, but the brushes aren't proprietary to CamelBak products. The large brush fits most standard water bottles from other brands, and the small brush cleans any straw-style lid or valve system that uses a similar diameter tube. If you've noticed your bottles starting to taste off even after washing, the issue is usually buildup inside components that don't get scrubbed during a normal rinse. Running the straw brush through valve assemblies and cap internals removes the biofilm that causes that stale water taste.... Read More
