How long does one gel can last?

Gel air fresheners typically provide fragrance for several weeks to a couple months depending on cabin temperature and ventilation. Warmer environments accelerate scent release.

Can I place this anywhere in the car?

Yes. The gel is stable in cup holders, under seats, or the glove box. Avoid direct sunlight and extreme heat, which speed up evaporation. Keep away from electronics and upholstery where gel contact could cause staining.

Will this leave residue or sticky spots?

Gel formulas are designed to stay contained in the can. As long as the can remains upright and intact, there's no spill or residue. If the can tips and breaks, clean the area promptly with warm water.
