5. Maintenance
Regular maintenance ensures optimal performance and longevity of your diffuser.
- Cleaning the Exterior: Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Cleaning the Atomizer: If the scent output decreases or appears inconsistent, the atomizer may need cleaning. Remove the essential oil bottle and atomizer unit. Gently wipe any visible residue. For a deeper clean, you may run a small amount of rubbing alcohol through the atomizer (without essential oil) for a short period, then rinse with clean water. Ensure it is completely dry before reassembling.
- Oil Replacement: Replace essential oil when the bottle is empty. Avoid mixing different oils directly in the bottle without cleaning first.
