Silicone Bottle Brush and Straw Cleaner Brushes for Hydroflasks, Insulated Bottles and Straws

Silicone is non-absorbent and will not lather, so always add hot, soapy water to your container first when using our bottle cleaner brush. This bottle cleaning accessory is very easy to keep clean - simply rinse it under your faucet, or pop it in the dishwasher to sterilize.

The minimum diameter of the bottle neck that our brush can fit into must not be less than 1.2 inches wide. It is compatible for use with a variety of popular vacuum insulated bottle brands, including YETI, S'well, Manna, Contigo, Hydro Flask, CamelBak, Nalgene, and ThermoFlask. Additionally, this versatile brush can also be used to clean your SodaStream bottle, thermos, pitcher, blender, baby bottle, vase, and delicate glassware.

However, please note that the brush head will not fit into narrow-neck containers such as regular beer, wine, kombucha or classic swing-top bottles.

Our bottle cleaner brush features a steel-shafted, non-flexible rod for sturdy cleaning, along with soft, flexible bristles that won't scratch delicate glassware. The BPA-free silicone construction ensures it won't stain, absorb grease or odors, and the bristles will retain their shape for long-lasting use.

For added convenience, the brush has a handle hanging hole for quick drying or storage, and it's easy to clean - simply toss it in the dishwasher.

Antimicrobial properties make this bottle brush a more hygienic choice compared to sponges or nylon brushes that can harbor unpleasant odors and grime after repeated use. The silicone material repels stains and smells, preventing nasty build-up for a healthier, more sanitary cleaning experience.

At 12.5 inches long, the sturdy steel shaft and rugged silicone bristle head provide deep cleaning power, allowing you to reach deep into tall, narrow containers such as insulated water bottles, flasks, thermoses, baby bottles, vases, and slender glassware. The non-scratching bristles are tough on gunk yet gentle enough to leave your favorite bottles, pitchers, and delicate items clean and free from any unsightly marks.

Whether you need to swish out slimy dregs from your flask, scrub soup from your thermos, or blitz residue in your baby bottle, this 12.5-inch bottle brush is up to the task. It's also an excellent travel companion, ensuring your on-the-go bottles and containers stay fresh and clean.

Durability is assured, as the bristles are designed to maintain their shape and won't break off or fall apart. The brush fits bottle necks 1 1/8 inches wide or larger and is heat-resistant up to 400°F, making it a long-lasting, reliable cleaning tool for all your hydration and food storage needs.
