How to Use a Hanging Car Diffuser

A hanging car diffuser uses fragrance oil, a wooden cap and a cord. Treat the selected product page and label as the final instructions. Different bottle and cap designs can have different directions, so do not assume another diffuser’s method applies.

  1. Position the bottle safely

    Work on a stable, wipe-clean surface. Fit the cord so the bottle can hang upright without touching the dashboard, mirror, trim or controls, and without obstructing the driver’s view.

  2. Check the bottle and cap

    Make sure the cap is secure and wipe any fragrance oil from the outside. Do not continue if the bottle, cord or cap is damaged.

  3. Activate only as directed

    If the product label tells you to tip the bottle, do it only for the stated time and return it upright immediately. More contact does not mean safer or better use and can increase the risk of leakage.

  4. Monitor it before driving

    Check that the bottle hangs freely and cannot strike a surface. Stop using it if you see leakage. Keep fragrance oil away from skin, eyes, children and pets, and follow the label for spill response and storage.
