With proper use and care, Freemie cups should be useful for about a year. To get the most life out of your Freemie Cups, follow our care recommendations. Be sure to boil the hard cup parts before initial use to make them airtight. 

Clean these parts after each use


  • Disassemble and wash all components that come into contact with breast milk (cup, breast flange, valve, valve base, barrier).
  • Hand wash parts using plenty of hot water and liquid dish-washing soap, then rinse clean with hot water for 10 to 15 seconds. Use a dedicated dish bin, and avoid washing parts with other dishes.
  • Treat all parts with special care. 
  • Clean and dry parts as soon as possible after each use.
  • When not in use, store parts disassembled and out of reach from infants and children.
  • Do not store assembled Freemie Cups in refrigerator, parts may become loose, malfunction or leak.


Before and after each use, visually inspect the individual components for cracks, chips, scratches, tears, discoloration or deterioration. In the event that damage is observed, please discontinue use until the parts have been replaced.

Additional Care

  • Boil hard cup parts any time to sanitize.
  • Clean tubing only if soiled by rinsing with very hot water and use after completely dry.
  • Clean Y-connector if soiled by washing in hot soapy water and rinsing very well. 


To maintain optimal performance of your Freemie Standard Cups, be aware that parts wear out over time through use. Plan on replacing parts as needed to avoid upset to your pumping schedule. At a minimum replace valves every 2-3 months or sooner if your use is heavy (e.g., more than 3-4 times per day).

Incorrect Care
Follow these instructions to avoid critical use errors such as leaking, milk in tubing, or other malfunctions.

  • Do not use steam sanitation (dishwasher, microwave bag, steam sterilizer) on any parts.
  • Do not use UV on any parts. 
  • Do not store any parts in refrigerator or freezer and protect parts from extreme heat and cold conditions.
  • Do not use abrasives or brushes that can scratch parts.
  • Do not wash tubing with soapy water.
