The best way to keep your HydraPak Products in excellent shape is to clean them with Bottle Bright, a biodegradable, chlorine free, all natural and environmentally safe cleaning tablet. No scrubbing required so it's perfect for cleaning flexible bottles, hydration reservoirs, soft flasks, and water storage containers.


The material used in most HydraPak products, Thermoplastic Polyurethane (TPU), is chosen for superior durability and flexibility. It is porous and can be stained like fabric. Staining is generally caused by food coloring used in gel or liquids and does not affect the functionality of the product; yet can be difficult to remove.

Again, we recommend using Bottle Bright to combat stains and odors in all your HydraPak products.


Some users may initially notice a plastic-like taste when using any of our products made with TPU. This taste typically subsides over time and can be eliminated by simply squeezing juice from a lemon into the product, filling it with water, and then freezing it. After frozen, remove, thaw, and rinse.

Bottle Bright has also been proven to resolve those having taste issues. If the problem persists, please reach out to our customer service team.


Keep your HydraPak products in a clean, dry place. Pro-tip: store your empty flasks, reservoirs, and hydration tubes in the freezer to keep them from getting funky.

Cleaning Your Reservoir

Keeping your reservoir clean is key to prolonging its life and keeping your water tasting fresh. Unlike, cleaning a tricky screw top reservoir, HydraPak reservoirs are top-shelf dishwasher safe and most are fully reversible which makes cleaning and drying a breeze.


As simple as it gets - reverse by placing your hand in the reservoir (make sure it's empty!), grab the bottom, and pull it back through the top opening. It's just like turning a sock inside-out. The molded opening can also be flipped after the reservoir body has been reveresed. Then, throw it in the dishwasher or rince with mild soap and water. Make sure to let the reservoir dry out completely while reversed.


The Shape-Shift features a removable baffle which locks for a slim profile and increased stabilization and unlocks for full volume. When unlocked it reverses for easy cleaning - throw it in the top-shelf of your dishwasher or rinse with mild soap and water. Make sure to let the reservoir dry out completely while reversed.


Many of our brand partners use a fixed baffle reservoir called the Shape-Loc. It can only be reversed up until the baffle is exposed but is still simple to clean. We recommend either using a bottle brush or Bottle Bright.

Method One - Fill your reservoir with warm water and use a bottle brush along with mild soap to scrub it clean. Rinse well and hang it upside down to dry.

Method Two - Fill your reservoir with warm water and drop in one-two Bottle Bright tablets, slide the top close and let sit for fifteen to thirty minutes (depending on the residue situation). Rinse and hang upside down to dry.

Tube & Bite Valve Cleaning

While throwing your tube set in the freezer is a great way to prevent anything funky from happening, if you are hydrating with anything other than water you will want to keep it clean. All of our components are removable for easy cleaning:

  1. Disconnect the drink tube from the reservoir
  2. Grasp the bite valve in one hand and tube in the other then pull the valve firmly to remove the bite valve from the tube
  3. Gently remove the silicone sheath from the valve and clean with Bottle Bright or mild soap and water
  4. Clean the inside of the tube by inserting the Hydrapak Tube Brush in the open end of the tube and scrub
  5. After drying the components, carefully reattach the sheath to the valve and re-install

Cleaning Your Stash Bottle

We recommend rinsing out your Stash bottle thouroughly before your first use and cleaning it regularly. Due to the Stash's flexible design, we do not recommend placing it in the dishwasher.

Method One - Fill your bottle with warm water and use a bottle brush along with mild soap to scrub it clean. Rinse well and set upside down to dry.

Method Two - Fill your bottle with warm water and drop in one Bottle Bright tablet, let sit for up to fifteen minutes. Rinse and set upside down to dry.

Cleaning Your SoftFlasks

All of our SoftFlasks are top-shelf dishwasher safe so they are very simple to keep clean. If you are fueling with energy gels or mixing your own nutrition mix, we recommend using a bottle brush or Bottle Bright to clean out any residue.

The bite valves and tubes can easily be removed for cleaning as well. Our Cleaning Kit provides you with both a tube brush and tablet of bottle bright to soak your valves in.
