A bottle washer and steriliser takes a repetitive feeding chore off your hands, but it still needs routine care. Milk residue, mineral deposits, and standing moisture can build up around the places water travels through, including the tank, spray arms, filter area, racks, and chamber. The good news is that a short cleaning routine after use, plus periodic deep cleaning and descaling, helps keep the machine working as intended.
This guide covers how to clean Momcozy Bottle Steriliser and Washer models BS03 (KleanPal Pro) and D8 (DeepClean). Always follow the instructions supplied with your exact model; do not immerse the main unit, use harsh abrasives, or run a cycle with baby items inside while you are descaling.
Why Regular Cleaning and Descaling Matters
Cleaning and descaling address different jobs. Cleaning removes milk residue, droplets, and debris from accessible surfaces and removable parts. Descaling targets mineral buildup left by water, especially in hard-water areas. Both matter because residue can affect water flow, while mineral deposits can leave water marks and make a machine harder to maintain.
Regular care also gives you a chance to inspect spray holes, racks, the residue cup or filter, and the water-tank connection. Momcozy support advises draining residual water after each use, cleaning areas that collect debris, and leaving the lid open to air-dry the unit. If you notice black spots, a persistent odor, poor water flow, or a visible deposit, pause use and complete a thorough clean before the next feeding cycle.
How Often Should I Clean My Steriliser?
A simple rhythm is easier to keep than waiting for buildup to appear. After each cycle, empty any remaining water, remove visible residue, and leave the lid open until the interior is dry. Wipe splashes from the exterior, top cover, water tank, and tank lid as needed with a soft damp cloth.
For BS03, clean the spray arms, shelves, shelf arms, and water storage tank regularly. For D8, run the Self-Clean program when needed and do a manual deep clean when you see residue or reduced flow. The D8 water-tank inlet should be cleaned at least monthly. Descale more often in hard-water areas or whenever the manual, display, or visible scale indicates that it is needed. Distilled or purified water can reduce mineral buildup where appropriate for your model.
How to Clean Momcozy Bottle Steriliser and Washer
Start with the appliance switched off, unplugged, cool, and empty. Keep the electrical base dry throughout. If you are cleaning after a wash cycle, allow hot surfaces to cool first. The right routine differs slightly by model because the removable parts are arranged differently.
Momcozy KleanPal Pro BS03
The BS03 has four main washable areas: the top cover, upper and lower spray arms, upper and lower brackets with shelf arms, and the water storage tank. Wipe the outer box, transparent top cover, water tank, and tank cover with a soft moist cloth. Do not pour water over the main unit.
- Lift the upper spray-arm assembly straight up. Open the lower shelf clasp with gentle pressure, then lift the lower shelf assembly with both hands. Remove the lower spray arm and turn the residue holder slightly to the right to remove it.
- Rinse the racks, upper and lower spray arms, residue holder, and other removable components with clean water. Check the spray holes for debris and rinse them so water can move freely.
- Wipe the inside of the chamber with a soft damp cloth. Reinstall the parts in the reverse order, making sure each piece is seated correctly and the spray arms can rotate freely.
Before an ordinary BS03 wash cycle, discard visible milk curds or heavy residue, briefly rinse items with obvious grease, and place one Momcozy detergent tablet in its designated area on the lower shelf. Invert bottles over the spray columns and keep small accessories separated so the arms can rotate without obstruction.

Momcozy DeepClean D8
For everyday exterior care, wipe the D8 main unit, top cover, water tank, and tank lid with a soft damp cloth. The D8 also offers an Auto Clean program for the chamber. Select the Self-Clean function and start the program according to the control-panel instructions; we recommend using its descaling tablet with this program for better cleaning results.
For a manual deep clean, remove the upper spray arm, upper rack, central water column, lower rack, and lower spray arm by lifting upward in that order. Remove the chamber filter, then rinse the spray arms, racks, and filter. Refit the parts in reverse order. At least monthly, clean the water inlet where the tank connects to the base with a cotton swab lightly moistened with food-grade white vinegar or citric-acid solution, then let the area dry completely before reinstalling the tank.
The D8 uses one detergent tablet for a normal wash cycle; place it in the lower rack, not in a bottle. Do not use foaming dish soap, which can overflow or cause errors. If the washer’s care needs have changed as your feeding setup has grown, the Momcozy Baby Bottle Washer collection shows the current washer models and compatible cleaning supplies.
How to Descale Momcozy Bottle Steriliser and Washer
Descaling should be done with the machine empty of bottles, pump parts, nipples, and other baby items. Check your current product guide before starting, because the exact program and tablet instructions are model-specific. The basic goal is to dissolve mineral buildup, then rinse every water-contact surface before the next baby-item cycle.
- Unplug the cooled unit and remove all baby items. Empty the tank and discard any residue from the chamber, filter, or residue holder.
-
Use the descaling method approved for your model. For the D8, Momcozy directs users to the Self-Clean program and recommends a Momcozy descaling tablet for better results. For BS03, use the current model instructions or approved descaling tablets rather than guessing at a detergent amount.
- When the descaling program is complete, rinse removable parts with clean water. Run the empty rinse/cleaning cycle specified by your manual so no descaler remains in the water path.
- Leave the lid open and allow the chamber and removable parts to dry fully. Reassemble only after the parts are dry and correctly seated.
Avoid treating a descaling cycle as a sterilising cycle for bottles. It is a maintenance task for the appliance, so baby items should stay out until the unit has been rinsed, dried, and returned to normal operation.
How to Descale a Bottle Steriliser Without Vinegar
If you prefer not to use vinegar, use a manufacturer-approved descaling tablet or a citric-acid descaling solution that is compatible with your specific machine. These options are designed to address mineral scale without adding a vinegar smell. Follow the label and your model guide exactly, and complete the required empty rinse cycle afterward.
Do not substitute foaming dish soap, bleach, abrasive powders, or an unapproved cleaner. A stronger household product is not necessarily a better choice for a bottle appliance, and it may damage components or leave residue that is difficult to rinse away.
FAQ
How to Use Vinegar to Clean a Bottle Steriliser?
Use vinegar only when it is compatible with your model instructions. Keep bottles and parts out of the appliance, use the recommended dilution or a food-grade vinegar wipe for the designated area, then rinse and run the required empty cycle. Never pour vinegar into a place the manual does not identify.
Can I Use Vinegar to Clean My Baby Bottle Steriliser?
It can be appropriate for some maintenance tasks, but the answer depends on the model and the area you are cleaning. For D8, Momcozy specifically permits food-grade white vinegar or citric-acid solution on a cotton swab for the water-tank inlet. Follow the manual for all other areas.
What Is a Good Descaling Solution for a Baby Bottle Steriliser?
The best first choice is the descaling tablet or solution approved by the appliance manufacturer. A compatible citric-acid descaler may also be suitable when the guide allows it. Use the amount, program, and rinse sequence specified for your model.
Which Is Better, Vinegar or Descaling Solution?
A manufacturer-approved descaling solution is usually the simpler option because its directions are written for the appliance. Vinegar can be useful for a permitted wipe-down or a manual-approved descale, but it can leave an odor if the unit is not rinsed thoroughly.
How to Clean a Steriliser With Baking Soda?
Do not use baking soda unless the manufacturer specifically approves it. Its gritty particles may be difficult to rinse from narrow water paths. A soft cloth, clean water, and the approved descaling method are safer choices for routine appliance care.
Can I Use Tap Water in My Bottle Steriliser?
Check your product guide. In hard-water areas, tap water can create scale more quickly. Momcozy support notes that distilled water is preferred when managing recurring mineral buildup; using it can reduce the frequency of descaling.
Is Vinegar Safe for Baby Bottles?
Vinegar should not be treated as a substitute for washing baby bottles. If you use it for appliance maintenance, keep baby items out of the unit during descaling and complete the manual-required rinse cycle before washing bottles again.
What Is the Best Way to Clean and Sterilise Baby Bottles?
First wash away milk residue with the correct detergent and a complete wash method, then use a sterilising process that follows the bottle, nipple, and appliance instructions. Separate small parts, position bottles for proper water flow, and inspect them after the cycle.
How Long Do Bottles Stay Sterile After Sterilising?
That depends on how and where they are stored after the cycle. A closed appliance can help protect clean items, but avoid opening it repeatedly, touching bottle interiors, or assuming an item is sterile indefinitely. Follow your appliance’s storage instructions.
What Is the Easiest Way to Sterilise Bottles?
The easiest method is the one you can use consistently and correctly. An automatic washer-steriliser can combine washing, sterilising, drying, and storage, provided you load it properly, use the approved detergent, and keep the machine clean.
Can You Sterilise Bottles Without Washing Them First?
No. Sterilising does not remove milk residue or grease. Bottles should be washed first, whether by hand or in an appliance cycle that includes washing, so the sterilising stage starts with visibly clean items.
Why Does My Steriliser Smell Like Vinegar After Descaling?
The most likely cause is residual vinegar in the water path or on removable parts. Rinse all removable pieces, run the empty rinse or cleaning cycle required by the manual, and let the unit air-dry with the lid open. Repeat the rinse if the odor remains.
When Should I Replace My Bottle Steriliser?
Replace it if the manufacturer advises replacement, a safety-related part is damaged, it leaks, it cannot be cleaned or descaled effectively, or it continues to malfunction after approved troubleshooting. Stop using a damaged appliance and contact the manufacturer for model-specific support.
Keep Your Bottle Washer Clean
A clean bottle washer is part of a reliable feeding routine. Drain water after use, let the interior dry, rinse removable parts regularly, and descale when mineral buildup calls for it. For BS03 and D8, use the model-specific support instructions for disassembly, Self-Clean or maintenance programs, approved tablets, and replacement parts. That small routine helps keep the appliance ready for the next wash cycle.
