Clean a formula mixer bottle after each use, and follow your model’s instructions for its removable parts and machine body. As a simple routine, wash the bottle and any removable mixing parts according to the care directions, then keep routine cleaning separate from model-specific maintenance.

That distinction helps you focus on the parts that need attention after feeding without treating every formula mixer the same way. For example, a bottle and its removable mixer parts may have routine washing steps, while machine upkeep can follow a separate schedule. Check your model’s instructions before washing components or handling the machine body, and use its maintenance guidance for any additional tasks. [1]
This approach keeps the routine practical: clean after use, then refer to your model’s directions when a task involves the appliance or ongoing upkeep. [2]
What to check before you start
Before cleaning, identify which parts of your formula mixer detach and check the manufacturer’s care instructions for your exact model. A bottle, lid, or mixing piece may be washable, while the appliance body or other components may need to stay dry; keep those areas separate rather than treating the whole unit like a regular bottle.
Look for instructions that show how parts come apart and which surfaces can be washed or immersed. For example, set removable pieces beside the sink, and keep the powered base away from the water while you follow the manual. If the instructions are unclear, check the manufacturer’s support page before cleaning instead of guessing.
Some machines also have model-specific maintenance steps beyond washing removable parts. For the Baby Brezza Formula Pro Advanced, the manufacturer provides a specific cleaning and descaling procedure, and says distilled white vinegar can also be used. [1] Follow that model’s directions rather than applying its procedure to a different mixer.
How to clean the bottle and mixing parts
Empty any formula left in the bottle, then take apart the removable pieces as your product manual directs. Keep the parts together so you can clean each one and avoid misplacing a small component.
Wash the bottle and removable components using the manual’s care instructions. Check the mixer’s specified cleaning areas for formula residue; a soft cloth or brush can help you reach a corner or seam, if the manual allows it.
If you have a model that calls for funnel cleaning, follow its stated schedule. For example, Baby Brezza’s FAQ says to remove the funnel after every fourth bottle and wipe beneath the formula container. [2]
Let the cleaned parts dry as the manufacturer directs before putting the mixer back together or storing the pieces. If a part still feels damp, give it more time rather than trapping moisture during storage.
Areas that are easy to overlook
Check easy-to-miss areas for formula residue, but follow the cleaning schedule and instructions for your exact mixer. A quick look around the container and mixing parts can help you spot buildup that a rinse of the bottle alone might leave behind.
If your model’s instructions call for it, inspect the underside of the formula container for buildup. On the Baby Brezza Formula Pro Advanced, the manufacturer recommends removing the funnel after every fourth bottle and wiping beneath the container to clear formula buildup. [2]
Also look closely at the wiper area and mixing tray if your mixer has them. A user response about the Formula Pro Advanced mentions cleaning the mix tray every fourth bottle and wiping the wiper above it. [3] Check around edges and corners where powder or damp formula might collect, rather than focusing only on the center of each part.
Use your model’s stated cleaning frequency instead of applying one schedule to every formula mixer. For example, a step recommended for one model may not match the routine for yours, so check the care instructions before adding it to your regular checklist.
Does the mixer need descaling too?
Yes. Descaling is a separate maintenance task from washing the bottle and removable mixing parts, so follow the instructions for your exact mixer rather than treating it as part of every wash.
How do I know when to descale it?
Check your machine’s manual or care guidance for the recommended descaling steps and timing. For example, Baby Brezza’s Formula Pro Advanced cleaning guidance mentions distilled white vinegar as an option. [1]
Can I use vinegar on every formula mixer?
Don’t assume the same descaling method works for every model. Use vinegar only if the instructions for your machine allow it, and follow their directions for how to use it.
What if my manual does not explain descaling?
Look for model-specific maintenance instructions from the manufacturer before trying a descaling method. Keeping this task separate from your usual bottle wash makes it easier to follow the right care steps for your machine.
Keep the routine tied to your model
Keep your cleaning routine simple: wash the bottle and removable mixing parts after feeding, then follow your model’s care instructions. [1] For example, treat a detachable mixing piece as a washable part only if your manual says how to clean it; use the steps specified for your mixer rather than assuming every model is cared for the same way.
Make the manual your next stop for maintenance and when to do it. [1] If you use a Baby Brezza model, its FAQ recommends removing the funnel after every fourth bottle and wiping under the formula container to clear formula buildup. [2] Other maintenance steps and their timing can depend on your model, so check the instructions before adding a task to your routine. Set a reminder for the schedule your manual gives, and keep the bottle and parts’ after-feeding cleanup separate from less frequent machine maintenance.
