How long does one Fresh Box last?

Duration depends on cabin size, airflow, and temperature. Larger cabins and heat will cycle the scent faster. Start with placement under a seat or in a door pocket and adjust position if you need stronger or lighter fragrance.

Will this stain or damage my interior?

Gel formula doesn't leak or drip. Keep it away from direct sunlight for extended periods and avoid placing it directly on upholstery or dash surfaces where condensation could pool.

Can I use this in a truck or SUV?

Yes. The 400g size works in any enclosed cabin. Larger vehicles may benefit from placement in the center console or under the front seat where air circulation naturally spreads the scent.
