Quick Answer
Clean the b.box + Lansinoh Spout Cup after every use by rinsing, washing with warm soapy water, and air-drying all parts completely to prevent mold and keep it safe for your toddler.
Why Thorough Drying Matters
The spout and valve areas trap moisture, which can lead to mildew if not dried properly. Even with regular washing, leftover water in hard-to-reach spots can cause odors and discoloration.
Make drying a deliberate step in your routine—not an afterthought—to keep the cup fresh between uses.
Know Your Cup's Limits
While the b.box + Lansinoh Spout Cup is designed for everyday use, not all cleaning methods suit every part. Always check the manufacturer's instructions for dishwasher and sterilizer compatibility, as high heat can warp silicone or plastic components.
When in doubt, hand washing is the gentlest option and helps preserve the cup's fit and function.
Step-by-Step Cleaning Routine
- Rinse immediately: After your toddler finishes drinking, rinse the cup and spout under warm running water to remove leftover milk, juice, or water. This prevents residue from drying and hardening. Don't let the cup sit with liquid in it for more than an hour—bacteria can multiply quickly.
- Disassemble all parts: Take apart the cup completely, including the spout, valve, lid, and any seals. Each piece needs individual cleaning to reach hidden areas where milk or saliva can collect. Check the valve for trapped debris—this is a common spot for mold to start.
- Wash with warm soapy water: Use a mild dish soap and a soft bottle brush or sponge to clean every part. Pay extra attention to the spout opening and the valve, gently scrubbing to remove any film. Avoid abrasive scrubbers that can scratch plastic and create hiding places for bacteria.
- Rinse thoroughly: Rinse all parts under clean running water until no soap residue remains. Leftover soap can affect the taste of water and irritate your toddler's mouth. A quick extra rinse never hurts—soap residue is easy to miss.
- Air-dry completely: Place all parts on a clean drying rack with the spout and valve facing down to allow water to drain. Let everything dry fully before reassembling the cup. If you're in a hurry, pat parts dry with a lint-free cloth, but air-drying is still best for thorough drying.
- Reassemble only when dry: Once every piece is completely dry, put the cup back together. Storing a damp cup can encourage mildew growth between uses. Do a quick visual check for any remaining moisture before storing.
