How long does the scent last before I need to replace it?

Gel fresheners typically last 4–6 weeks depending on temperature and ventilation in your car. Lifespan varies with climate — warmer conditions speed evaporation.

Can I hang this from my mirror or does it need to sit somewhere flat?

The Fresh Box is designed for flexible placement — hang it, set it in a cup holder, or clip it to an air vent. Mounting method is up to you.

Will this leave residue or stain if it leaks?

Gel formula is designed to stay contained, but if spilled on fabric, spot-clean with cool water and mild soap right away. Test on a hidden area first if you're concerned about your specific upholstery.
