How to Clean Your Advanced Manual Breast Pump

How to Clean Your Advanced Manual Breast Pump

Did you know cleaning (washing with soap and water) and sanitizing are two separate steps? Cleaning with soap and water removes dust, leftover milk, etc. Sanitizing with high heat removes bacteria or viruses that may be present. Both steps are important.

It is recommended that you clean (wash) your pump before you ever use it, as well as after each use. In the U.S., the CDC also recommends that you sanitize before first use and once daily for babies under 3 months or medically fragile. For detailed steps read How to Keep Your Breast Pump Kit Clean.

Before cleaning your pump, set the handle aside. If you happen to drip milk on this part at some point, simply wipe it with a soft damp cloth as needed.

Cleaning your pump:

  1. Wash your hands.
  2. Take your flange kit apart, separating the valve, membrane, and diaphragm from the flange.
  3. Rinse milk off by holding the pump pieces under cool, running water.
  4. There are two ways to clean your pump.
    • Option 1: Basin Fill a clean basin with warm water and mild dish soap. Submerge the flange, bottle, valve, membrane, diaphragm, sealing disk and cap ring. Use a soft, clean brush as needed. Rinse well with clean water. 
    • Option 2: Dishwasher Place disassembled parts on the top rack of the dishwasher, placing smaller parts in a top-shelf, dishwasher safe basket. Be careful not to set anything heavy on top of breast pump parts. Run dishwasher.

Sanitizing your pump:

  1. Wash your hands.
  2. Option 1: Stove top Place flange, bottle, valve, membrane and diaphragm in pan of boiling water for five minutes, stirring frequently. Do not let any pieces settle on the bottom of the pan. Remove immediately with clean tongs.
  3. Option 2: Microwave Sanitizing Bag Place pieces mentioned above into the Evenflo Feeding Silicone Steam Sanitizing Bag and use as instructed.

After cleaning and/or sanitizing, let the pump dry:

  1. Clean the counter surface.
  2. Wash your hands.
  3. Lay pump parts on clean paper towels, a clean dish towel, or drying rack. Do not set anything heavy on top of pieces while they dry.
  4. After the parts have dried, re-assemble your pump.

Place disassembled pump parts in a pan of boiling water for five minutes. Stir frequently. DO NOT allow parts to rest on bottom of pan as they may melt or become damaged.


Use Evenflo Silicone Steam Sanitizing Bad according to instructions.

IMPORTANT: DO NOT CLEAN HANDLE IN MICROWAVE or with sanitization bags as it will damage the handle and the PUMP WILL NO LONGER WORK.
