The Suction Base Bottle Brush with Nipple Cleaner makes cleaning baby's bottles quick &easy. The 2-in-1 brush head has both sponge and durable bristles designed for thorough cleaning. This bottle brush is ideal for cleaning those hard to reach places in the baby's bottle. The nipple cleaner that sits inside the suction cup base has tiny grooves that provide improved cleaning to the narrow parts of the nipple. The removable suction cup base will stick to most smooth surfaces and stores the bottle brush upright keeping it out of the sink. Having the bottle in the right position also keeps it ready to use and promotes fast drying.
