How many sprays does one bottle deliver?

That depends on how much you press the trigger. Light mist uses less product, heavy saturation uses more. One 3.0 oz bottle lasts longer if you spray once or twice per week versus daily.

Will this stain my interior or leave residue?

Liquid spray formulas are designed to dry without staining fabric or plastic. Avoid spraying directly onto leather or suede — spray into the air and let it settle, or apply to ventilation louvers.

Can I return this if the scent doesn't match what I expected?

Contact ModSupply customer service with your order number and details about the scent profile. Return eligibility depends on condition of the bottle and how much product remains.
