How long does one brick last?

Scent intensity drops gradually over weeks depending on cabin heat, airflow, and how strong you like the smell. Most drivers replace when the aroma fades noticeably—no hard cutoff date. Store in a cool place between drives to extend life.

Can I place this anywhere in the car?

Yes. Dash, center console, cup holder, door pocket—anywhere stable that won't block vision or controls. Avoid direct sunlight for extended periods, as heat speeds scent release. Keep away from vents if you want slower diffusion.

Will this stain or damage my interior?

The brick won't leak or drip like liquid fresheners. Place it on a flat surface—no adhesive needed. If it contacts vinyl or leather for weeks on end, test-fit in a hidden spot first to make sure the scent oils don't discolor trim.
