When it comes to your baby’s health, you should not take any risks, especially in Singapore's tropical humidity where bacteria thrive. A bottle steriliser is an essential piece of equipment to ensure your baby’s feeding gear is germ-free. In this guide, we’ll walk you through how to clean a bottle sterilizer and maintain it for long-term use.
Why Clean the Bottle Washer/Steriliser?
An infant’s immune system is still developing, making them vulnerable to environmental germs. In a typical Singaporean home—whether you are living in an HDB or a Condo—moisture is constant, which can turn your feeding equipment into a breeding ground for mould. Knowing how to clean a bottle steriliser is vital for your baby’s safety.
SG Mummy Tip: In Singapore's humid weather, "air-drying" alone isn't enough. Always use the "Dry" function on your Momcozy steriliser to prevent stagnant water from attracting pests or growing mildew.
- Prevent Bacteria Growth: Leftover milk residue in a warm, moist environment quickly leads to bacteria. Regular cleaning is the only way to avoid these harmful microorganisms.
- Maintain Sterilisation Efficiency: Singapore's tap water, while safe, can lead to "limescale" (mineral deposits) over time. This buildup makes the heating element less effective. Frequent cleaning ensures it works properly to keep your baby’s bottles as clean as possible.
- Odor Control: Sour milk smells can cling to plastic bottles. Regular maintenance keeps everything smelling fresh, making feeding time more pleasant for your little one.
- Support for Working Mums: For many mummies returning to work after their 16-week MOM maternity leave, keeping a clean steriliser at the office or home is key to a stress-free pumping routine.
Alongside bottle care, nasal hygiene is another daily concern. In air-conditioned environments common in SG, babies often get dry or stuffy noses. Using a gentle baby nasal aspirator ensures they can breathe and feed comfortably.
How to Wash and Clean a Bottle Washer and Steriliser Regularly?
Let’s use the Momcozy KleanPal Pro as our example. Following a routine prevents residue buildup and keeps your machine efficient.
Step 1: Disassemble Removable Parts
- First, pull the upper shelf and upper jet arm assembly straight up to remove it.

- Gently press the lower shelf clasp and remove the holders.

- Lift the lower shelf with both hands, then take out the lower spray arm and residue holder.


Step 2: Internal Wipe Cleaning
Use a soft, damp cloth to wipe the exterior, including the transparent cover and water tank. In Singapore's dusty urban environment, a daily wipe keeps your unit looking new.

Step 3 & 4: Deep Wash & Rinse
Wash all components with warm soapy water using a baby-safe detergent (available in most SG supermarkets). Rinse thoroughly to ensure no soapy residue remains.

Step 5: Reassemble
Once dry, reassemble in reverse order. Ensure all parts "click" back into place to maintain the airtight seal for sterilisation.
How to Deep Clean a Bottle Washer and Steriliser: Descaling Methods
Water in Singapore is classified as moderately soft, but mineral buildup still occurs. Descaling is essential to keep the heating element working at 100% efficiency.
Method 1: Vinegar Solution (Natural & Cheap)

- Mix 1:1 ratio of white vinegar and water.
- Pour into the water tank and run one cycle (without bottles).
- Let it sit for 30 minutes, then flush with fresh water.
- Run a final water-only cycle to remove the vinegar scent.
Method 2: Citric Acid (The Quick Fix)
Many SG mummies prefer citric acid powder for its lack of smell compared to vinegar.
- Dissolve 1 tbsp of citric acid in 250ml of warm water.
- Pour into the tank, run a cycle, and let it sit for 20 minutes.
- Rinse and run a blank cycle.
How Often Should I Clean My Steriliser in Singapore?
Due to the high usage typical of SG households, we recommend a deep descale every 2 weeks. A quick wipe-down should be done daily. If you notice a white chalky layer on the metal plate, it's time to descale immediately.

Localised FAQs for Singapore Mummies
Is Singapore tap water okay for sterilisers?
Yes, Singapore tap water is safe. However, it still contains minerals that cause limescale. For less maintenance, some mummies prefer using distilled or filtered water in their Momcozy units.
Can I use standard dish soap?
It is best to use a specialized "Baby Bottle Cleanser" to avoid harsh chemicals or strong fragrances that might linger in the machine.
My machine has a "Dry" mode. Do I still need to wipe it?
Yes. The Dry mode removes moisture, but milk proteins can still settle on the surfaces. A weekly wipe with a damp cloth ensures the interior stays hygienic.
Does descaling affect my Corporate Benefits/Insurance?
While insurance usually covers the purchase of medical-grade pumps, proper maintenance ensures you don't need to pay out-of-pocket for replacements due to negligence-related damage.
Conclusion
Maintaining a clean feeding environment is the best way to keep your baby healthy. From sterilising bottles correctly to regular descaling, every small step counts. For extra comfort during long feeding sessions, don't forget to use a nursing pillow to support your posture.
As your little one grows and starts their weaning journey, keeping a clean baby high chair area will be your next priority!
