Unplug the humidifier and empty any remaining water
Disassemble the unit into its main parts (tank, lid/cap, base, filter if applicable)
Wash the parts with warm water
Use a soft brush or microfiber cloth to remove visible mineral buildup
Fill the tank with a 1:1 mixture of white vinegar and water
Let the tank soak for 30–60 minutes
For heavy scale, soak longer as needed
Scrub the inside surfaces with a soft brush
Rinse thoroughly with clean water until the vinegar smell is gone
Clean the base/housing with a damp cloth; avoid soaking electrical components
If the base has mineral deposits, wipe with vinegar and water, then wipe again with clean water
If the humidifier has a filter, follow the manufacturer instructions (do not soak unless the label allows it)
If the filter is washable, rinse gently and let it dry completely
Empty and rinse the reservoir and any removable parts again after soaking
Dry all parts completely with a clean towel or by air-drying
Reassemble only when fully dry
Replace the water daily and keep the unit dry between uses
