Can You Put Breast Pump Parts In Dishwasher

When it comes to parenting, convenience is key. And for breastfeeding mothers, the breast pump is a valuable tool that allows them to provide breast milk for their babies even when they are not physically present. However, the convenience of using a breast pump also comes with the responsibility of keeping it clean and safe for your baby. One common question that many breastfeeding moms have is whether they can put breast pump parts in the dishwasher. In this article, we will explore this topic in depth, providing you with all the information you need to make an informed decision.

The Importance of Cleanliness

Before we delve into the dishwasher question, it’s essential to understand why cleanliness is crucial when it comes to breast pump parts. The primary reason is that breast milk is a perfect breeding ground for bacteria. Any leftover milk residue on your breast pump parts can quickly become a breeding ground for harmful bacteria, putting your baby’s health at risk.

Dishwasher-Friendly Breast Pump Parts

Now, let’s get to the heart of the matter – can you put breast pump parts in the dishwasher? The answer is yes, but with some important caveats. Not all breast pump parts are dishwasher-friendly. It’s essential to distinguish between parts that can be safely cleaned in the dishwasher and those that cannot.

Dishwasher-Friendly Parts

  1. Bottles and Caps: Most breast pump manufacturers design their bottles and caps to be dishwasher-safe. These parts are typically made of sturdy materials that can withstand high temperatures without warping or losing their shape.
  2. Valves and Membranes: Valves and membranes are often dishwasher-safe, but it’s crucial to check the manufacturer’s instructions to be sure. Some may recommend hand washing to prolong the life of these parts.

Parts to Avoid

  1. Tubing: Breast pump tubing should never be put in the dishwasher. The high heat and water pressure can damage the tubing, making it less effective or even causing it to crack.
  2. Breast Shields: Breast shields are usually not dishwasher-safe. They are made of softer materials that can become misshapen or damaged in the dishwasher.

Proper Dishwasher Cleaning

If your breast pump parts are dishwasher-friendly, here are the steps to ensure a thorough and safe cleaning:

  1. Disassemble: Take apart all the components of your breast pump, including bottles, caps, valves, and membranes.
  2. Pre-Rinse: Before placing them in the dishwasher, give the parts a quick rinse to remove any residual milk.
  3. Use a Mesh Bag: To prevent small parts from getting lost or damaged in the dishwasher, place them in a mesh bag designed for delicate items.
  4. Top Rack Only: Always put your breast pump parts on the top rack of the dishwasher. This ensures that they are exposed to less heat and water pressure.
  5. Avoid Heat Dry: Skip the heat drying cycle and allow the parts to air dry instead. High heat can damage some components.
  6. Inspect After Washing: After the dishwasher cycle is complete, inspect all parts to make sure they are clean and in good condition.


In conclusion, you can put certain breast pump parts in the dishwasher, but it’s essential to know which ones are dishwasher-safe and follow proper cleaning procedures. Maintaining the cleanliness of your breast pump is vital to ensure the safety of your baby’s milk supply. Remember to always refer to the manufacturer’s instructions for specific guidance on cleaning and maintenance.
