Keeping your breast pump clean is essential for protecting your baby’s health, maintaining milk quality, and extending the life of your pump. Whether you're using a wearable electric breast pump or a manual pump, this in-depth guide will show you how to properly clean and sterilize every component. We'll also share safety tips, troubleshooting advice, and recommended schedules for sterilization.

Why Is Cleaning and Sterilizing So Important?

Every drop of breast milk is full of nutrients—and it's also sensitive to contamination. Residual milk left on pump parts can breed bacteria, which may lead to illness or infection in your baby. Regular cleaning and sterilization help prevent this, ensuring your milk stays pure and your pump works as it should.

Parts of the BabyGuru Wearable Breast Pump

Before cleaning, it’s important to identify which parts require washing and which do not. For the BabyGuru Wearable Breast Pump, clean the following parts after each use:

• Flange (breast shield)
• Duckbill valve
• Diaphragm
• Milk collection cup
• Backflow protector (if included)

Important: The pump motor (hub) should never be submerged in water. Clean only with a damp cloth.

Step-by-Step: How to Clean Your Breast Pump After Each Use

1. Disassemble Immediately After Use

Remove all parts that come into contact with milk. This prevents milk residue from drying and becoming harder to clean.

2. Rinse with Cold Water

Rinse each piece under cold running water to remove milk proteins and fats. Avoid rinsing in a sink basin to prevent exposure to bacteria.

3. Wash Thoroughly

Hand Wash Method:

• Use a clean basin designated for infant feeding items.
• Wash parts with warm water and a mild, fragrance-free soap.
• Use a soft brush or sponge (also reserved for baby items).

Dishwasher Method (if allowed by product manual):

• Place parts on the top rack.
• Use hot water and a heated dry cycle.
• Use a baby-safe detergent free of dyes and perfumes.

4. Rinse and Air Dry

Rinse thoroughly under clean running water. Air dry on a clean towel or drying rack in a location protected from dust, insects, or kitchen splashes.

5. Store Properly

Once parts are dry, store in a clean container or a zip-top bag until next use. Avoid stacking wet parts to prevent mold or bacterial growth.

How to Sterilize Your Breast Pump Parts

While cleaning removes milk residue, sterilizing kills bacteria and viruses. It’s especially important for:

• Babies under 3 months
• Premature babies
• Babies with compromised immunity
• After illness or infection

When to Sterilize

• Before first use
• At least once per day
• After illness or if pump has been exposed to germs

Boiling Water Method

1. Fill a large, clean pot with enough water to fully submerge all pump parts.
2. Bring to a rolling boil.
3. Place parts (except motor) into the pot using clean tongs.
4. Boil for 5–10 minutes.
5. Remove with tongs and place on a clean towel to air dry completely.

Steam Sterilizer

Use an electric steam sterilizer following the manufacturer’s instructions. Make sure pump parts are correctly arranged for full steam exposure.

Microwave Sterilization Bags

1. Place pump parts into a sterilization bag.
2. Add water according to the bag’s instructions.
3. Microwave for the recommended time (usually 3–5 minutes).
4. Let bag cool before handling.

UV Sterilizers (Optional)

Some parents use UV sterilizers for added peace of mind. These are great for small parts like valves and membranes but should not replace hot steam for milk-contact parts.

How to Sterilize Manual Breast Pumps

Manual breast pumps are simpler but still require diligent cleaning. Most have fewer components, typically including:

• Handle
• Flange
• Valve
• Pump body
• Milk bottle or cup

Cleaning Process:

1. Disassemble all parts immediately after use.
2. Rinse with cold water to remove milk residue.
3. Hand wash or place dishwasher-safe parts on the top rack.
4. Use bottle brushes to clean small crevices.
5. Rinse and air dry completely before reassembling.

Sterilization Options:

• Boiling: Safe for most manual pump components.
• Steam/Microwave: Verify materials are microwave-safe.
• Sterilization tablets: Useful when traveling (no boiling required).

Be cautious with plastic seals, membranes, or parts that may warp with high heat. Check your manual for brand-specific guidelines.

Safe Storage Between Feeds

If you’re pumping multiple times in a day and cannot wash parts immediately:

• Rinse used parts with cool water
• Store in a clean, sealed container in the refrigerator
• Wash and sterilize within 24 hours

Never store unwashed pump parts at room temperature.

Pro Tips for Long-Term Pump Hygiene

• Use a separate basin and brush just for breast pump and baby bottle parts
• Label parts to keep sets together (especially if using multiple pumps)
• Replace valves and membranes every 1–3 months depending on usage
• Check parts for wear and tear like warping or cracking

❌ What NOT to Do

• Don’t use harsh cleaning agents, bleach, or scented soap
• Don’t microwave the motor or non-microwave-safe parts
• Don’t skip drying—moisture breeds bacteria
• Don’t use the same parts without washing between sessions (unless stored in fridge as above)

✅ Summary Cleaning Schedule

Task	Frequency
Disassemble and rinse parts	After every use
Wash with soap and water	After every use
Sterilize	Once per day (or as needed)
Wipe motor unit	Daily or as needed
Replace membranes/valves	Every 3–6 months
