How to Clean Your Hydration Vest Bladder

Noticed a strange taste or smell in your water during a run? It’s probably time to clean your hydration vest bladder. Regular cleaning keeps your water fresh, prevents bacteria and mold from forming, and helps your gear last longer. Here’s how to do it ...

How Often Should You Clean It?

You don’t need to deep-clean your bladder after every run, but a quick rinse after each use is essential. If you’re using electrolyte drinks or running in hot weather, do a deeper clean every few uses.

Always dry the bladder completely before storing it to avoid mildew or odors.

Step-by-Step: How to Clean Your Hydration Vest Bladder

Nathan hydration bladders like the 1.8L Replacement Vapor Bladder, 1.5L Quickstart Bladder, and 1.6L Insulated Bladder are easy to clean. The steps below apply to all three.

1. Disassemble the parts

Remove the cap or top slider, empty remaining liquid, and detach the hose from the bladder. For the Vapor Bladder, gently reach inside and detach the internal baffle from the two plastic posts.

2. Wash with warm soapy water

Use mild dish soap and warm (not hot) water to clean the inside of the bladder. Run soapy water through the hose and bite valve as well.

3. Rinse thoroughly

Flush clean water through all parts until no soap residue remains.

4. Air-dry completely

Hang the bladder upside down with the top open. Let the tube hang vertically so water can drain.

Pro tip: Insert balled-up paper towels to help speed up the drying process.
