How to Use
Sublimation-felt air fresheners hold vibrant prints and give weeks of steady fragrance when loaded, cured, and topped up correctly. This guide covers carrier bases, application methods, sealed curing, and an optional reusable spritz.
Materials & Tools
| Item | Purpose |
|---|---|
| Fragrance oil or essential oil | The scent load |
| Augeo diffuser base | Slow-release carrier |
| Dipropylene glycol (DPG) | Steady-release fixative |
| Isopropyl alcohol | Fast-drying carrier for top-ups or quick bursts |
| Blotting paper / paper towel | Absorbs surface pooling |
| Fine-mist sprayer | Even coverage |
| Petri dish | For controlled soaking |
| Zip-lock bags | Airtight curing |
| Small spray bottles (5–10 ml)* | Optional for customer top-ups |
Carrier Options & Ratios
| Carrier | Pros / Cons | Oil : Carrier Ratio |
|---|---|---|
| Augeo base | Slow, consistent release; ideal for long-lasting performance. | 10–25 % oil : 90–75 % base |
| Dipropylene glycol (DPG) | Inexpensive, steady release; needs longer curing. | 10–25 % oil : 90–75 % DPG |
| Isopropyl alcohol | Fast-drying. Best for refills, not long-term diffusion. | 10–20 % oil : 90–80 % alcohol |
Application Tips
- Petri Dish Method: Lay the freshener flat and add fragrance using a pipette.
- Use a fine-mist sprayer for designs that may bleed.
- Under-loading causes weak scent: 2–3 sprays lasts one day at most.
- The felt should be evenly darkened, never dripping.
- Turn gently to saturate both sides.
- Let each side dry for around 10 minutes before recoating.
- Multiple light coats give best performance and protect the print.
Sealed-Bag Curing
- Place treated fresheners in a zip-lock bag and press out air.
- Leave sealed for 24–48 hours at room temperature.
- Air out for 30–60 minutes before packaging or hanging.
Optional Reusable Re-Spritz
Include a 5–10 ml spray bottle so customers can refresh the scent.
- Shake before use.
- Lightly mist every 3–5 days.
- Store the bottle somewhere cool and dark.
Testing & Optimisation
- Test oil ratios at 10%, 15%, 20%, 25%.
- Compare longevity and strength.
- Record results to find your ideal blend.
Troubleshooting
- Uneven scent: reduce oil or use a slower carrier.
- Weak performance: increase oil or ensure full saturation.
- Fades fast: increase load and allow full curing.
- Print bleed: apply lighter coats with drying in between.
Safety & Storage
- Keep carriers away from flames.
- Label mixes with date and oil percentage.
- Store finished fresheners in sealed bags until use.
*Small spray bottles are optional for reusable refresh kits.
