Safety first
- Wear gloves: concentrated fragrance oil irritates skin. Wash splashes off with soap and water.
- Keep diffusers out of reach of children and pets. The liquid is harmful if swallowed, and cats are sensitive to many oils.
- Wipe up drips straight away. Fragrance oils mar finished wood, paint and plastic, so set the bottle on a coaster or tray.
- Keep diffusers away from open flames and heaters, especially bases with alcohol.
- Label the bottle with its contents and 'Not for consumption.'
Steps
- Put on gloves and set the bottle on a tray lined with paper towel.
- Measure the base and fragrance from the calculator. Pour the fragrance into the bottle through the funnel, then add the base.
- Cap and swirl, or stir with a glass rod, until the mix is clear and even.
- Insert the reeds. Use fewer reeds in a small room and more for a stronger scent.
- After about 1 hour, flip the reeds so the soaked ends are in the air and scent reaches the room faster. Do this over the sink or tray.
- Let the reeds saturate for 24–48 hours for the full scent.
- Flip the reeds about once a week to refresh the scent. Flip more often for more scent, less often to make it last.
- Replace the reeds every 2–3 months, or when you change scents. They clog with dust and old fragrance.

Premixed and odorless (often a glycol ether or an isoparaffin blend). The easiest, most reliable choice. Follow the supplier's fragrance ratio, usually 20–30%.
Flip the reeds once a week, or when the scent fades. Swap in new reeds every refill.
If something goes wrong
- Reeds not wicking
- The base is too thick (IPM or fractionated coconut are slow) or the reeds are clogged. Use a commercial base or DPG, add a few % perfumer's alcohol, and use fresh fiber reeds.
- Scent too weak
- Add more reeds, flip them more often, or raise the fragrance toward 30%. Move the bottle to a spot with gentle air movement, like a hallway.
- Scent too strong or runs out fast
- Remove some reeds and flip less often. Keep it away from heaters and direct sun.
- Mix looks cloudy or separated
- The fragrance isn't compatible with the base. Shake it, or switch to a DPG or commercial base, which mix with most fragrance oils.
