Versatile long handle: Retractable handle adjusts to reach a range of cup and bottle sizes so you can clean deep, narrow, or tall containers without straining. Designed to reach tricky spots other brushes miss. Soft sponge head for thorough cleaning: The brush head uses a soft sponge that conforms to the interior shape of cups and bottles, reaching curves and corners for a close, even clean without scratching surfaces. Effective stain and residue removal: The sponge construction cleans away stubborn stains and residues from daily use, helping restore cups and bottles to a sanitary, readytouse condition. Spacesaving storage: The tail of the brush includes a hanging hole for convenient storage on a hook, keeping your sink area or drawer organized and allowing the brush to dry between uses. Suitable compatibility and performance: Works with a wide range of containers — including standard cups, travel mugs, water bottles, narrowneck bottles, and most reusable drinkware — and adapts to different interior shapes thanks to the retractable handle and conforming sponge head. Use scenarios: Clean tall travel mugs and insulated bottles that are hard to reach with short brushes. Remove milk and formula residue from baby bottles and narrowneck containers. Rinse tea, coffee, or juice stains from everyday cups and reusable water bottles. What you get: a retractablehandle bottle and cup cleaning brush with a soft sponge head and a hanging hole for easy storage — designed to make routine cleaning quicker, more thorough, and less effortful.
