How to Clean and Sterilise Your Haakaa Breast Pump Parts: A Complete Hygiene Routine

Keeping your breast pump parts clean is essential for your baby’s health and the longevity of your pump. Whether you’re using a manual silicone pump like the Generation 3 160/250ml Silicone Breast Pump or a wearable electric model, a consistent hygiene routine helps prevent bacterial growth and ensures safe milk collection. In this guide, we’ll walk you through the best practices for cleaning and sterilising your Haakaa pump parts, including tips for silicone care and everyday pump parts cleaning.

Unlike some plastic pumps, silicone pumps are naturally non-porous and resistant to bacterial buildup, but they still need proper care. The good news is that silicone is easy to clean and can withstand high temperatures without degrading. Follow these steps to keep your pump parts spotless and your milk collection hygienic.

Why Proper Hygiene Matters for Silicone Pumps

Breast milk is a living fluid that can spoil quickly if contaminated. Even small traces of milk residue left on pump parts can harbour bacteria, which may cause digestive upset or infections in your baby. Silicone is less prone to harbouring bacteria than plastic, but it still requires thorough cleaning after each use. A good breast pump hygiene routine also prevents mould growth in hard-to-reach areas, especially around valves and membranes.

For silicone pumps like the Haakaa Generation 3, the risk of contamination is lower because there are no small crevices or tubes—just a simple one-piece design. However, if you use accessories like the Silicone Breast Pump Strap or a collection bottle, those parts need attention too. By making cleaning a habit, you protect your baby and extend the life of your pump.

• Always wash your hands before handling pump parts.
• Rinse parts with cool water immediately after use to remove milk residue.

Daily Cleaning Routine: Step by Step

After each pumping session, disassemble your pump completely. For the Generation 3 Silicone Breast Pump, separate the silicone body from the base and any valves. Rinse each part under cool running water to remove milk residue—hot water can cause milk proteins to stick. Then, wash with warm soapy water using a mild, fragrance-free dish soap. Use a dedicated bottle brush to scrub all surfaces, including the inside of the pump body and the valve opening. Pay special attention to the nipple area where milk collects.

Rinse thoroughly with warm water to remove all soap residue. Shake off excess water and place parts on a clean drying rack or a paper towel. Allow them to air-dry completely before reassembling. Do not use dish towels, as they can transfer bacteria. For a deeper clean, you can use a steam steriliser or boil the parts (see next section). This daily routine is the foundation of good pump parts cleaning and ensures your pump is ready for the next use.

• Use a dedicated brush set for pump parts to avoid cross-contamination.
• If you can’t wash immediately, rinse and refrigerate parts in a sealed bag for up to 4 hours.

How to Sterilise Your Silicone Pump Parts

Sterilisation is recommended at least once a day for newborns or premature babies, and weekly for older infants. Silicone handles heat well, so you have several safe options. The easiest method is to boil the parts in a large pot of water for 5 minutes. Ensure all parts are fully submerged and not touching the bottom of the pot (use a steamer basket if needed). After boiling, use tongs to remove parts and let them air-dry on a clean surface.

Alternatively, you can use a steam steriliser (microwave or electric) designed for baby bottles. Place the disassembled parts in the steriliser and follow the manufacturer’s instructions—typically 5–10 minutes. Cold water sterilising tablets are also effective, but rinse parts with cooled boiled water before use. Avoid using bleach or harsh chemicals, as they can damage silicone and leave harmful residues. For the Silicone Breast Pump Strap, simply wipe it down with soapy water and air-dry; it doesn’t need sterilising.

• Boiling is the most cost-effective method—just watch the time to avoid damage.
• Steam sterilisers are convenient and preserve silicone flexibility.

Caring for Silicone: What to Avoid

Silicone is durable but not indestructible. To keep your Haakaa pump in top shape, avoid using abrasive sponges or brushes that can scratch the surface. Scratches create hiding spots for bacteria and can cause the silicone to become cloudy over time. Also, avoid high heat above 120°C (250°F), which can warp or melt the material. This means no dishwasher top rack if your dishwasher has a sanitise cycle that exceeds that temperature—check your manual.

Never use oil-based soaps or lotions on silicone, as they can break down the material. Stick to mild dish soap and water. If your pump develops a lingering odour from milk fats, soak it in a solution of white vinegar and water (1:4 ratio) for 30 minutes, then rinse thoroughly. Baking soda paste can also help remove stains. With proper silicone care, your pump should last for months or even through multiple children.

• Inspect your pump regularly for cracks or cloudiness—replace if damaged.
• Store pump parts in a clean, dry container between uses.

Quick Tips for On-the-Go Cleaning

When you’re away from home, keeping your pump clean can be challenging. Carry a small bottle of fragrance-free soap and a collapsible basin for washing. If you don’t have access to clean water, use alcohol-free wipes designed for baby products to wipe down the parts, then rinse as soon as possible. For travel, consider packing a spare set of parts so you can rotate them and avoid using a damp pump.

Another tip: store your pump parts in a dedicated, ventilated bag or container to prevent moisture buildup. Avoid sealing wet parts in a plastic bag for more than a few hours, as this encourages mould. If you’re using a wearable electric pump, follow the manufacturer’s cleaning instructions—many have similar silicone components that can be washed and sterilised the same way. Remember, a quick clean is better than no clean, but always aim for a full wash within a few hours.

• Bring a small drying rack or a clean cloth to air-dry parts after washing.
• Use the SqueezieDose Silicone Dispenser Set for storing small amounts of soap or wipes.

A clean breast pump is a safe breast pump. By following this complete hygiene routine—daily washing, regular sterilisation, and proper silicone care—you can protect your baby from contaminants and extend the life of your Haakaa pump. Whether you use the Generation 3 Silicone Breast Pump or another model, these tips will help you maintain excellent breast pump hygiene with minimal effort. Happy pumping!
