Unscrew the silver cap, carefully remove and discard the plastic stopper, and replace the silver cap. Untie the raffia from the bundle of reeds, place ALL the reeds into the bottle and fan them out. After approximately twenty-four hours flip the reeds over, taking care not to spill any oil. To refresh (if you can no longer smell the fragrance) turn the reeds over again. Eventually all the liquid will evaporate.
A new set of 8 reeds is provided with each refill. The used reeds must be discarded (they become dusty, saturated with oil and no longer wick properly), and the bottle emptied of any residue oil which has become thick and discoloured. If a different fragrance is being used, wash the bottle out in hot soapy water, rinse in very hot water and ensure it is dry inside before refilling. We recommend that you always start with fresh oil and a new set of reeds.
Discolouration of the oil may occur after a week or two. Some oils are prone to oxidation when exposed to air and will develop a characteristic rust-like colour. This does not affect the fragrance.
The 100ml diffuser will last approximately two months. Evaporation of the oil will be quicker in an air-conditioned environment where the air is drier, and also in the very hot summer months.
