Introducing the OXO Tot Bottle & Cup Cleaning Set – Grey. Cleaning baby bottles and sippy cups doesn’t have to be a chore with the OXO Tot Cleaning Essentials Set for Bottles & Cups. The Bottle Brush easily reaches into tall bottles and is designed to reduce water spray while cleaning. The bristles are durable for serious scrubbing while still being safe for glass baby bottles. The straw and detail brushes get into those little hard-to-reach nooks and crannies in sippy cups and their parts, and all three brushes have non-slip handles for a firm grip, even when your hands are wet. The Bottle Brush comes with a convenient stand that stores the Brush in two positions that keep the bristles away from germs, and features a pour spout for easy cleaning.
