Learn how to descale your Baby Brezza machine using Universal Descaling Tablets. Step-by-step instructions for Formula Pro and Bottle Washer Pro to remove limescale and keep bottles safe.

Quick answer

Descale your Baby Brezza machine every 4–6 weeks using Baby Brezza Universal Descaling Tablets. Dissolve one tablet in water, run a descaling cycle, then rinse thoroughly. This removes limescale, maintains performance, and keeps bottles safe. Always check your model's manual for specific instructions.

Why descaling matters for your Baby Brezza

Limescale and mineral deposits build up inside any appliance that heats water. In a Baby Brezza, this scale can clog the mixing chamber, reduce heating efficiency, and even affect the taste or safety of formula. Regular descaling with Baby Brezza Universal Descaling Tablets removes these deposits. The tablets are non-toxic, hypoallergenic, and fragrance-free, so they are safe for your baby's items. They contain 24 tablets per pack, enough for several months of maintenance. Note: these tablets do not work on the Baby Brezza Steriliser Dryer; use the manufacturer's recommended method for that appliance.

How often should you descale?

The frequency depends on your water hardness and how often you use the machine. As a general rule, descale every 4–6 weeks for daily use. If you live in a hard water area, you may need to descale every 2–3 weeks. Signs that descaling is due include white chalky deposits, slower water flow, or a noticeable change in the taste or temperature of the formula. For the Bottle Washer Pro, descaling also helps maintain washing performance and prevents mineral buildup on bottles and parts.

Step-by-step descaling process

Prepare your machine: Turn off and unplug your Baby Brezza. Remove the water tank, funnel, and any removable parts. Empty any remaining water. For the Formula Pro, also remove the powder container and wash it separately if needed. Checkpoint: Never descale while the machine is plugged in.
Mix the descaling solution: Fill the water tank with 500 ml of warm (not hot) water. Add one Baby Brezza Universal Descaling Tablet. Wait until it fully dissolves, which takes about 5 minutes. Do not use more than one tablet unless instructed by your model's manual. Common mistake: Using boiling water can damage the tablet's effectiveness and the machine's internal components.
Run the descaling cycle: For Formula Pro: Reassemble the machine without powder, then run a water-only cycle (select water only, not formula) and dispense about 250 ml. Let it sit for 10 minutes, then dispense the remaining solution. For Bottle Washer Pro: Pour the solution into the wash compartment and run a wash cycle without bottles. Check your manual for model-specific steps. Checkpoint: The solution should be warm, not hot, and should not be ingested.
Rinse thoroughly: Empty the tank and refill with clean water. Run two full water-only cycles to flush out any remaining descaling solution. For Bottle Washer Pro, run a rinse cycle twice. This ensures no residue remains that could affect taste or safety. Common mistake: Skipping the rinse can leave a chemical aftertaste in your baby's formula or on bottles.
Clean and dry: Wipe down the exterior with a damp cloth. Wash removable parts (funnel, tank, etc.) with warm soapy water, rinse, and air dry. Reassemble the machine once all parts are completely dry. Checkpoint: Ensure all parts are dry before reassembling to prevent mold or mildew.
Record the date: Mark your calendar or set a reminder to descale again in 4–6 weeks. If you have hard water, aim for every 2–3 weeks. Regular descaling extends the life of your machine and keeps it running efficiently. Next step: Consider the Baby Brezza care bundle for Bottle Washer Pro to keep detergent and descaling supplies on hand.
