Cleaning bottles is a breeze with Dr. Brown's Deluxe Bottle Brush. The soft yet sturdy bristles are angled to help prevent splashing and to thoroughly clean every corner of baby bottles, sippy cups, and more. The Deluxe Bottle Brush offers two ways to clean – the brush head cleans the entire bottle, and the ridged nipple cleaner on the base is designed to quickly and easily clean bottle nipples. The no-slip handle is comfortable and easy to hold and long enough to reach all the way into bottles and sippy cups. Use the suction cup base for convenient and hygienic sink-side storage. Plus, the Deluxe Bottle Brush comes with a bonus small parts brush to clean vent inserts, reservoirs, and other hard-to-reach areas. BPA Free. Keep vent inserts and reservoirs clean in any Dr. Brown's bottles with Dr. Brown's Cleaning Brushes. Happy Feeding stays happy when you use the cleaning brush to clean and clear blockages of dried milk and formula. The multi-purpose, lightweight brush easily maneuvers through all Dr. Brown's bottle components – especially the Internal Vent System – for a fully clean and functioning bottle interior. Brushes can also be used to clean sippy and straw cups when baby's feeding progresses. Replace lost or worn brushes with this 4-pack or just have a few spares on hand. BPA free.
