Meguiar’s® Whole Car Air Refresher will remove any unwanted odours from your car by moving through the ventilation system across all areas in the vehicle and reaching even the most difficult to get places, leaving a fresh scent.Unlike traditional odour removers that simply fall down onto floor mats and seats, Meguiars Whole Car Air Refresher penetrates the complete interior of your car, truck, or SUV eliminating unwanted odours. The odour eliminating mist moves through the ventilation system of your vehicle, across the headliner, and in-between all other hard to reach areas, eliminating odours and leaving a fresh scent in its place. How-to use: Vehicle should be unoccupied with no person, pets, or plants inside.
