Reach curved and narrow spaces more conveniently with this Flexible Straw and Bottle Cleaner Brush. Designed with a slim, flexible stem, the brush can be used for cleaning compatible reusable straws, bottle tubes, narrow-neck containers and other hard-to-reach openings. Its flexible construction helps navigate selected curves and internal sections that rigid brushes may have difficulty reaching. Use with water and an appropriate dishwashing liquid, moving the brush gently through the item without forcing it. Confirm brush diameter and length before use to ensure compatibility. Rinse thoroughly after cleaning and allow the brush to dry completely between uses. Bristle stiffness, flexibility, total length and material vary by model. A practical reusable cleaning accessory for straws, sports bottles, tumblers and other narrow kitchen or drinkware components.
