How long does one can last?

Duration depends on how often you spray and how well your cabin is sealed. Light use in a well-ventilated car lasts weeks; daily sprays in a closed space will deplete it faster. One can covers multiple applications.

Can I use this in a detailing shop or storage area?

Yes. This works anywhere you need quick odor control — detail bays, covered parking, storage units between uses. Spray lightly and let air circulation do the work.

Will this leave residue on my dash or upholstery?

Aerosol spray disperses into the air rather than depositing liquid. Aim for open space inside the cabin and let it settle naturally. Avoid direct spraying onto leather or plastic trim.
