How long does one bottle last?

Longevity depends on how often you spray and how large your vehicle interior is. Since you control the trigger, light daily use will stretch a 3.0oz bottle significantly longer than heavy, frequent application.

Can I use this on fabric or just spray into the air?

Spray bottles work best as air fresheners—mist directly into the cabin. Test on a small, hidden fabric area first if you're unsure, since liquid products can sometimes leave marks on certain materials.

Does this come with a mounting clip or does it just sit loose?

Only the spray bottle is included. You'll need to position it in a cup holder, storage pocket, or secured location—no clip or bracket is part of this product.
