How long does one can last?

Gel formulas release scent gradually. Duration depends on ventilation, cabin size, and how much you like the smell. A 90G can typically goes 2–4 weeks before you'll need a replacement.

Can I use this in any vehicle?

Yes. Place it in a cup holder, hang it from a vent clip, or position it on the dash. Works in cars, trucks, SUVs — anywhere you want fresh air.

Will this stain or damage interior materials?

Gel cans are sealed. Keep it upright to avoid leaks. If you're placing it loose in a cup holder, use a coaster or absorbent mat underneath as a precaution.
