Why Cleaning Your Eufy Breast Pump Matters

Before diving into the steps, it’s important to understand why cleaning your breast pump thoroughly is so crucial. Breast milk is rich in nutrients—not just for your baby, but also for bacteria and mold. If milk residue dries inside the pump parts, it can create a perfect environment for harmful microorganisms to grow.

Even if you can’t see or smell anything, bacteria can still be present. These can contaminate future milk表达, potentially causing digestive issues or infections in your baby. Additionally, leftover milk can clog valves and membranes, reducing suction efficiency and shortening the life of your pump.

Eufy pumps are designed with hygiene in mind, but they still require consistent care. The good news? Cleaning your Eufy breast pump doesn’t have to be complicated or time-consuming. With the right routine, it can become a quick, automatic part of your pumping schedule.

What You’ll Need to Clean Your Eufy Breast Pump

Before you start, gather these supplies to make the process smooth and effective:

• Warm water (preferably filtered or boiled and cooled)
• Mild, fragrance-free dish soap (baby-safe options like Dawn Free & Clear or Cetaphil are great)
• A clean bottle brush or small cleaning brush
• A dedicated drying rack (preferably with a cover or mesh top)
• A clean towel or paper towels
• A microwave-safe sterilizing bag (if using steam sterilization)
• Access to a microwave, electric sterilizer, or pot for boiling (optional, for sanitizing)
• A small bowl or container for soaking parts

Tip: Keep a dedicated “pump cleaning kit” in your pumping area so everything is ready when you need it. This saves time and reduces the chance of skipping steps.

Step 1: Disassemble the Pump After Each Use

The first and most important step in cleaning your Eufy breast pump is complete disassembly. You can’t clean what you can’t reach, so take the time to break down every part that comes into contact with milk.

How to Disassemble Your Eufy Pump

Most Eufy breast pumps—like the Eufy Breast Pump S1, S1 Pro, or Dual Electric models—follow a similar design. Here’s how to take them apart:

1. Remove the milk collection bottles: Twist or pull them off the pump body.
2. Detach the flanges: These are the funnel-shaped parts that go over your breast. Gently twist or pull them away from the pump.
3. Take off the valves and membranes: These small, delicate parts sit between the flange and the bottle. Carefully peel them off—they’re usually snap-on or twist-on.
4. Remove any connectors or tubes: If your model has tubing, disconnect it from the pump motor. Note: Only the parts that touch milk need to be cleaned—the motor unit should never be submerged.
5. Check for hidden parts: Some models have small silicone seals or gaskets. Make sure you remove these too.

Pro Tip: Lay out the parts in the order you removed them. This makes reassembly faster and helps you remember where everything goes.

What NOT to Disassemble

Never take apart the pump motor or electrical components. These should never come into contact with water. Only clean the parts that touch milk or your skin. If you’re unsure, refer to your Eufy user manual—it will show exactly which parts are removable.

Step 2: Rinse Immediately with Warm Water

Once disassembled, rinse all milk-contact parts under warm running water as soon as possible. This prevents milk from drying and sticking to surfaces, which makes deep cleaning much harder.

How to Rinse Effectively

• Hold each part under warm water for 10–15 seconds.
• Use your fingers to gently rub off any visible milk residue, especially around the edges of the flange and valve.
• For narrow areas like valve openings, use a stream of water from the faucet or a squeeze bottle to flush out milk.
• Rinse the bottles thoroughly, inside and out.

Why warm water? Hot water can warp plastic parts, while cold water doesn’t dissolve milk fats as well. Warm water strikes the perfect balance.

Pro Tip: Use a Rinse Bottle

Keep a small squeeze bottle filled with warm water near your pumping station. After pumping, give each part a quick squirt to rinse before washing. This is especially helpful if you’re pumping at work or on the go.

Step 3: Wash with Mild Soap and a Brush

Rinsing removes loose milk, but washing with soap is essential to eliminate bacteria and residue. Use a mild, fragrance-free soap and a dedicated brush to scrub every surface.

How to Wash Each Part

1. Flanges: Use the bottle brush to scrub the inside and outside. Pay special attention to the rim and the area where the valve attaches—milk often collects here.
2. Valves and membranes: These are delicate. Gently rub them between your fingers or use a soft brush. Avoid stretching or tearing them.
3. Bottles and caps: Scrub the inside with the brush and rinse thoroughly. Check for milk buildup in the threads.
4. Connectors and tubes: If your model has tubing, flush it with soapy water using a syringe or bottle brush. Rinse well to remove all soap.

Soaking for Tough Residue

If you notice dried milk or cloudiness, soak the parts in a bowl of warm, soapy water for 5–10 minutes before scrubbing. This softens residue and makes cleaning easier.

Avoid using harsh cleaners, bleach, or antibacterial soaps. These can leave harmful residues or degrade silicone parts over time.

Step 4: Sanitize Regularly (Daily or Every Few Uses)

Washing removes visible dirt, but sanitizing kills bacteria, viruses, and mold. The CDC and lactation experts recommend sanitizing breast pump parts at least once a day, especially if your baby is under 3 months, premature, or has a weakened immune system.

Method 1: Steam Sterilization (Recommended)

Steam sterilization is fast, effective, and safe for most Eufy parts.

• Microwave Steam Bags: Place clean, rinsed parts in a microwave-safe sterilizing bag. Add the recommended amount of water, seal the bag, and microwave for 60–90 seconds. Let cool before removing.
• Electric Steam Sterilizers: These devices use steam to sanitize in 8–10 minutes. Simply place parts inside, add water, and press start.

Tip: Always check that your Eufy parts are labeled “steam-safe” before using this method. Most are, but double-check your manual.

Method 2: Boiling Water

If you don’t have a sterilizer, boiling is a reliable alternative.

1. Fill a pot with enough water to fully submerge all parts.
2. Bring water to a rolling boil.
3. Add pump parts and boil for 5 minutes.
4. Use tongs to remove parts and place them on a clean drying rack.

Caution: Don’t boil the motor or tubing (if not designed for it). Over-boiling can damage silicone membranes.

Method 3: UV Sterilizers

UV sterilizers use ultraviolet light to kill germs without heat or water. They’re convenient and safe for all pump parts, including electronics (though only the milk-contact parts need sanitizing). Simply place parts inside, close the lid, and run the cycle (usually 5–10 minutes).

How Often to Sanitize

– Daily: If your baby is newborn, premature, or immunocompromised.
– Every 2–3 uses: For healthy, full-term babies.
– After illness: Always sanitize if you or your baby have been sick.

Step 5: Air-Dry Completely Before Reassembling

Never reassemble your pump while parts are still wet. Moisture can trap bacteria and lead to mold growth.

How to Dry Properly

• Place all parts on a clean, dry drying rack with good airflow.
• Let them air-dry completely—usually 1–2 hours, depending on humidity.
• Turn parts upside down so water drains out of crevices.
• Avoid using towels to dry, as they can transfer lint or bacteria.

Best Drying Racks for Breast Pump Parts

Look for racks with:
– A mesh or slotted design for airflow
– A cover to protect from dust
– Enough space for all your parts

Some moms use baby bottle drying racks, which work perfectly for pump parts.

Can You Use a Dishwasher?

Most Eufy breast pump parts are not dishwasher-safe. The high heat and harsh detergents can warp plastic, degrade silicone, and leave residues. Always check your user manual. If it says “top rack only” or “dishwasher safe,” proceed with caution—but air-drying is still recommended.

Step 6: Store Clean Parts Properly

Once dry, store your clean pump parts in a clean, dry place. Avoid plastic bags or containers that trap moisture.

Storage Tips

• Use a clean, breathable storage bag or container.
• Keep parts together so nothing gets lost.
• Store in a cabinet or drawer away from dust and pets.
• If pumping at work, use a dedicated pump bag with a clean compartment.

Never store wet or damp parts—even if they seem dry on the outside, moisture can linger inside valves or tubes.

How to Clean the Pump Motor and Tubing

The motor unit and tubing (if applicable) require special care.

Cleaning the Motor

– Wipe the outside with a damp cloth and mild soap.
– Never submerge or spray water on the motor.
– Use a dry cloth to remove moisture.
– Store in a dry, dust-free area.

Cleaning Tubing

If your Eufy model has tubing:
– Only clean if milk has entered the tubes (rare, but possible).
– Flush with warm soapy water using a syringe.
– Rinse thoroughly and hang to dry completely.
– Never use the pump with wet tubing—it can damage the motor.

Tip: To prevent milk from entering tubing, ensure the bottle isn’t overfilled and the pump is positioned correctly.

Troubleshooting Common Cleaning Issues

Even with the best care, problems can arise. Here’s how to handle common issues:

Cloudy or Milky-Looking Parts

This is usually milk residue or mineral buildup. Soak in a solution of 1 part white vinegar to 3 parts water for 15 minutes, then scrub and rinse thoroughly.

Sticky or Stiff Valves

Silicone valves can degrade over time. If they feel sticky, less flexible, or cracked, replace them. Eufy sells replacement kits online.

Milk Smell or Taste

If stored milk smells soapy or metallic, it may be due to lipase enzyme activity—not poor cleaning. This is harmless but can be reduced by scalding milk before freezing. Always clean parts thoroughly to rule out contamination.

Pump Losing Suction

Check for:
– Worn or damaged valves/membranes
– Improper assembly
– Clogged parts

Clean and inspect all parts. Replace any that are cracked or stretched.

Mold or Mildew

If you spot mold (black or green spots), discard the affected part immediately. Mold can produce toxins harmful to babies. Deep-clean all other parts and review your drying routine.

How Often Should You Clean Your Eufy Breast Pump?

Here’s a quick reference:

• After every use: Rinse and wash all milk-contact parts.
• Daily or every 2–3 uses: Sanitize using steam, boiling, or UV.
• Weekly: Deep-clean with vinegar soak if needed.
• Monthly: Inspect valves, membranes, and flanges for wear.

Consistency is key. A quick 5-minute clean after each session prevents buildup and makes sanitizing faster.

Final Tips for Maintaining Your Eufy Breast Pump

• Replace parts regularly: Valves and membranes should be replaced every 1–3 months, or sooner if damaged.
• Keep a spare set: Having a second set of clean parts lets you pump while the others dry.
• Label parts: If you have twins or share parts, label them to avoid mix-ups.
• Follow the manual: Eufy provides model-specific cleaning instructions—always refer to it.
• Stay organized: Use a pump cleaning checklist or app to track cleaning and part replacements.
