How long does one bottle last?

Depends on how often you spray and vehicle size. Light use (2–3 sprays per week) stretches a bottle several weeks. Heavy use in a larger cabin burns through it faster. Keep one on hand and replace when scent fades.

Will this stain or damage upholstery?

Spray application is light and designed for interior use. Test on a hidden area of fabric or trim first if you're concerned, and avoid spraying directly onto delicate materials. Most modern automotive textiles handle air freshener spray fine.

Can I use this on leather seats?

Yes, spray mist is safe for leather. Apply a light burst from a distance rather than soaking the material, and wipe excess with a soft cloth if needed. The atomizer design prevents over-saturation.
