Diffuser maintenance Clean the nozzle every week, pour alcohol after dry the water,and run the machine for about 1 hour. The nozzle can be cleaned before changing essential oils to avoid mixing of essential oils. The concentration of each essential oil is different, so the consumption of essential oil is also different, and the spray effect is also different. Some essential oils may not be visible to the naked eye. But the fragrance of essential oils spread out, indicating that the machine is operating normally. After receiving the machine, you can test it with alcohol first. If you find quality problems, Contact the buyer in time for after-sales service. If there is a problem after using the essential oil, we do not provide free return and exchange services, only repair services. #aromadiffuser #aromatherapy #gift #Accumulator #aromatic #timing #Portable #Fragrant #cararomadifuuser #scentdiffuser
