Wynn’s AircoFresh™ is a special formula that quickly neutralizes odors that form in the evaporator core, housing and duct work in the vehicle’s HVAC system and interior. Unlike traditional odor removers that simply fall down onto floor mats and seats AircoFresh™ penetrates the complete interior of your car, truck or SUV eliminating unwanted odors. The odor eliminating mist moves through the HVAC system, across the headliner and into other hard to reach areas eliminating odors and leaving a fresh scent.
