How long does one can last?

Gel fresheners typically provide scent for several weeks, depending on temperature and air circulation in your car. Warmer conditions speed up fragrance release.

Will this damage my dashboard or interior surfaces?

Place the can in a cup holder or secured location where it won't tip. Avoid direct contact with upholstery or sensitive trim — the gel won't stain, but prevention is cleaner than cleanup.

Can I adjust how much scent comes out?

With gel cans, scent release is steady and can't be dialed down. If the fragrance feels too strong, move it further from air vents or crack a window occasionally.
