For busy parents, finding ways to save time is a top priority. When you’re pumping several times a day, the constant cycle of washing and sterilizing breast pump parts can feel like a never-ending chore.

Using a dishwasher can be a safe and effective way to clean your pump equipment, freeing up precious minutes.

This guide provides a step-by-step process to help you confidently use your dishwasher to keep your pump parts hygienic and ready for your baby.

Using a dishwasher isn’t just about convenience; it can also be a reliable method for cleaning and sanitizing.

Many dishwashers have high-heat settings and sanitizing cycles that are effective at removing bacteria and milk residue. This helps ensure your baby’s milk supply is safe.

However, it’s crucial to do it correctly to protect the integrity of your pump parts and ensure a thorough clean.

For parents interested in alternative cleaning devices, such as the Baby Brezza, we have a dedicated guide on whether you can safely wash breast pump parts using a Baby Brezza.

This can be particularly useful if you’re looking for other convenient cleaning solutions.

Before you start, always check your breast pump’s user manual to confirm which parts are dishwasher-safe.

Follow these steps to clean your breast pump parts effectively and safely.

Immediately after pumping, take apart every component of your pump kit. This includes flanges, valves, membranes, connectors, and milk collection bottles.

Don’t skip any small pieces. Rinse each part under cool running water to remove any remaining milk residue.

This initial rinse is important because it prevents milk proteins from “cooking” onto the parts in the dishwasher’s heat, which can be difficult to remove later.

Small components like valves, membranes, and bottle rings can easily get lost or fall to the bottom of the dishwasher, where they might melt on the heating element.

To prevent this, place all small, lightweight parts into a closed-top dishwasher basket or a mesh laundry bag.

This keeps them secure and ensures they get properly cleaned without risk of damage. Many baby brands sell baskets specifically designed for this purpose.

Place the dishwasher basket and any larger plastic parts, like flanges and bottles, on the top rack of the dishwasher.

The heat is generally less intense on the top rack, which helps prevent plastic from warping.

Avoid cramming parts together; give them enough space to allow water and detergent to circulate freely for a thorough cleaning.

For the best results, use a hot water wash cycle. If your dishwasher has a “sanitize” or “high-temp” setting, this is an excellent option for breast pump parts.

The high temperatures are effective at killing germs. However, always refer to your pump manufacturer’s instructions, as some plastics may not tolerate extremely high heat.

If you’re unsure, a standard hot water cycle is a safe alternative.

When it comes to detergent, it’s best to choose one that’s specifically formulated for baby items or is free from harsh chemicals, dyes, and fragrances.

Using a baby-safe soap ensures no harmful residues are left on the parts that come into contact with breast milk.

If you have hard water, consider using a rinse aid to prevent water spots and film from building up on your equipment.

Once the dishwasher cycle is complete, the next steps are just as important for ensuring safety and hygiene.

Remove the parts from the dishwasher. Even if you used a heated dry cycle, some components, especially those inside the basket, may still be damp.

Place all parts on a clean, unused paper towel or a dedicated drying rack in an area protected from dust and dirt.

Avoid using a cloth dish towel to dry your pump parts, as towels can harbor bacteria and transfer lint onto your equipment.

Allow them to air-dry completely before reassembling. Trapped moisture can encourage mold and bacterial growth. You can quick this drying process, using breast pump cleaning hack.

Before storing or using the parts, give them a quick inspection. Look closely for any remaining milk film or soap residue.

If you notice any, you’ll need to wash them again by hand to ensure they are perfectly clean for your next pumping session.

• Check Manufacturer Guidelines: This is the most critical rule. Not all pump parts are created equal. Some may be made from materials that can warp or degrade in the high heat of a dishwasher. Always confirm which pieces are dishwasher-safe by checking the manual for your specific pump model.
• What Not to Wash in a Dishwasher: Generally, you should never put your breast pump’s motor/unit or the tubing in the dishwasher. The tubing is difficult to dry completely, and trapped moisture can lead to mold growth, which could then get into your expressed milk. Only clean tubing if milk has accidentally entered it, and follow the manufacturer’s instructions for doing so. Learn more about tubing here.
• Washing vs. Sanitizing: While a dishwasher’s sanitize cycle is effective, the CDC recommends daily sanitization for extra protection, especially for babies who are under three months old, were born prematurely, or have a weakened immune system. You can sanitize parts after washing by boiling them in water for five minutes or using a steam sterilizer system.
