How long does one 90g can last?

Gel formula typically lasts 3–4 weeks depending on cabin size and ventilation. Heat and air conditioning cycles speed up fragrance release, so summer driving drains it faster than winter.

Can I use this in a hot car or direct sunlight?

Yes, but prolonged heat accelerates gel breakdown. Place it on a dash vent or under a seat to extend life. Avoid direct windshield mounting where intense sun can warp the can.

Will this stain or damage interior trim?

Gel formula is less likely to drip than liquid sprays, but keep it away from leather and fabric. If spilled, wipe immediately with a damp cloth. Test on a hidden area first if you're concerned about your specific trim material.
