How long does the scent last?

Paper air fresheners typically hold their scent for 3–4 weeks depending on ventilation and sun exposure. Once scent fades, the freshener can be replaced or repositioned to a shadier spot to extend life.

Will this damage my windshield or mirror?

No. The hanging string is designed to suspend the freshener without adhesive. Hang it on your rearview mirror or a secure interior clip point — no drilling or permanent attachment required.

Can I use this in a new or used vehicle?

Yes. This works in any vehicle with a hanging point. If your car already has a strong interior smell, the new car scent may take a few days to become the dominant fragrance.
