【4-Pack Heavy-Duty Cleaning Kit】 Built for rigorous use, this rugged kit features a 12-inch straw brush length (304mm) paired with 100mm nylon bristles and a 12mm-wide design, effortlessly replacing disposable bottle brushes and flimsy pipe cleaner packs. Ideal for eco-conscious homes, the compact yet durable tools tackle stainless steel straws, protein shaker balls, and keyboard crevices with precision. These bulk pipe cleaners bulk dive deeper than standard water bottle brushes or bulky electric cleaners, reaching narrow spaces without bending—solving problems where conventional tools fall short. 【Scratch-Free Cleaning & Baby-Safe Materials】 Crafted with BPA-free materials, this straw cleaner brush extra long doubles as a gentle straw brush cleaner for baby bottles and glass pipe cleaner tasks. Soft silicone tips and non-abrasive bristles scrub silicone straws and narrow-neck bottles safely, avoiding harsh straw cleaners that risk chemical residue. Its reinforced core resists bending, outlasting disposable alternatives. 【Heat-Resistant & Shape-Restoring Design】 Engineered with a semi-flexible core, the Stanley straw cleaner brush bends to fit tumbler curves yet snaps back flawlessly—even after scrubbing metal straw cleaner-grade steel. The 304-grade handle and heat-resistant bristles (60°C-proof) outperform warping green pipe cleaners, making it ideal for sanitizing straw cleaner brush set kits or deep-cleaning tasks. 【Multi-Purpose Cleaning Brush】 The CIDYAUST straw cleaning brush handles water bottles, teapots, hookahs, and even sink drains. Compatible with pipe cleaners for weed accessories, hummingbird feeders, and pipe cleaners craft projects, it replaces disposable straw brushes for cleaning straws and niche tools. A versatile eco-solution for Stanley cup maintenance or delicate glass pipe cleaner care. 【PROFESSIONAL CLEANING BRAND】 PROFESSIONAL CLEANING BRAND-CIDYAUST straw brush is produced by CIDYAUST.
