The Cleaning Brush

The Cleaning Brush is the ultimate companion to The Boly Bottle. Engineered specifically to fit the 500ml bottle, it reaches every part of the interior — no guesswork, no struggling with an ill-fitting generic brush.

Made from food-safe silicone, it is gentle on the 316 medical-grade stainless steel inner while still removing residue and build-up effectively. Silicone is naturally resistant to mould, bacteria, and odours, keeping your cleaning routine hygienic and hassle-free.

Simple, effective, and designed with parents in mind.
