As with all baby feeding and breast pump items, Moxxly Flow needs to be thoroughly cleaned and sanitized before use. Wash and sanitize everything that milk touches which include the bottles, lids, valves, and flanges. You do not need to clean your tubes and adapters unless they come into contact with milk.
Wash your Flow parts before your first use and between every session. Wash with soap and warm water or on the top rack of a dishwasher.
Sanitize your Flow by placing the parts in a pot of boiling water for 10 minutes.
