After every pumping session, wash all components that have come in contact with the breast and breast milk. This includes breast shields, diaphragms, duckbill valves, bottles, bottle caps, and nipples.

It is very important to never sterilize or wash the tubing or pump motor. It is not necessary to clean the breast shield body and diaphragm cap cover after every pumping session, and only if they come in contact with breast milk.

Before you use your breast pump for the first time, you will need to prepare by sterilizing all parts that will come in contact with your breast or breast milk. This usually includes the breast shields, diaphragms, duckbill valves, bottles, bottle caps, and nipples. There are a few different methods you can use to sterilize your breast pump parts.

There are a few different methods you can use to sterilize your breast pump parts. The simplest and easiest sterilization method is the boiling water technique.

• Use a pot large enough to fit all of your pump parts without touching. Parts need to have enough room to move around, in order to prevent warping.
• Fill the pot with enough water to cover and fully saturate the parts, leaving plenty of space for a rolling boil.
• Place on a stove top and bring to a rolling boil for 5 minutes, and then remove pot from heat.
• Allow to cool to a manageable temperature, and then carefully remove parts.
• Set sterilized parts on a clean paper towel away from a high traffic area (we do not recommend drying on a cloth towel because they can harbor bacteria).
• Let air dry completely prior to assembly.

Please remember that frequent sterilization can cause your pump parts to deteriorate faster. If you follow a regular wash routine, you shouldn’t need to sterilize more than just once.

We recommend you hand wash all pump parts whenever possible. For this method, you will need a separate wash basin, a dedicated sponge or bottle brush, clean paper towels, standard dish soap, and access to warm water.

• Fill up a wash basin with warm, soapy water.
• Add your pump parts and move them around.
• Wash each part individually with a sponge or bottle brush.
• Rinse thoroughly under cool, running water.
• Set to air dry on a clean paper towel away from high traffic areas (we do not recommend drying on a cloth towel because they can harbor bacteria).
• Let air dry completely prior to assembly.

All Zomee breast shields, bottles, and other hard plastic accessories are BPA-Free and can go through the dishwasher without worry of harmful residue. Keep in mind that this high heat washing may cause parts to wear down faster than expected. Do not wash silicone parts like duckbill valves, membranes, and diaphragms in the dishwasher. These parts are delicate and should be hand washed whenever possible.

Yes! Always remember that for microwave steam cleaners or cleaning solutions, follow the manufacturer’s instructions. If your care provider has instructed you to steam sterilize your pump parts, you should do so. In this case, please be aware that you may need to replace your parts more frequently.
