Bottle brush Hydro Flask BRS415 — nylon bristles, plastic handle, black/blue

Hydro Flask BRS415 bottle brush is designed for routine cleaning of reusable bottles and drinkware. The brush features a compact head with durable nylon bristles for effective scrubbing of narrow-neck containers and internal surfaces, and a molded plastic handle that offers a comfortable grip and control. Available in black and blue, this bottle brush is intended to reach inside bottles, straws and crevices of lids to remove residue and support hygienic maintenance of everyday hydration gear.

Advantages

The nylon bristles resist abrasion and maintain shape through repeated use, enabling consistent cleaning performance. The plastic handle is lightweight and shaped for secure handling when cleaning deep or slim bottles. The brush head profile and bristle density are chosen to balance scrubbing power with safe contact on common bottle materials, reducing the risk of scratching while removing deposits.

Suitable for

• Cleaning reusable water bottles with narrow necks
• Cleaning bottle straws and internal tubing
• Reaching crevices in caps, lids and threaded openings
• Routine washing of drinkware made from stainless steel, plastic or similar materials

Key specifications

• Bristle material: nylon
• Handle material: plastic
• Color options: black and blue
• Brush head type: narrow/compact for bottle interiors and straws

How to use

Rinse the brush before first use. Insert the brush head into the bottle or straw and move it with gentle back-and-forth or circular motions to dislodge residue. Apply dish soap to the brush or bottle interior as needed for more thorough cleaning. After use, rinse the brush and allow it to air dry in a well-ventilated area. Use the detail end to clean cap crevices and lids by working into threads and seals until residue is removed.

Usage recommendations

For best results, clean bottles and lids after each use and allow all components to dry completely. Replace the brush when bristles become noticeably frayed or misshapen. Avoid using abrasive cleaners or high-temperature sanitizing methods that may deform the plastic handle or affect bristle performance.
