Directions : Shake aerosol well before use. Start the vehicle and turn on the air conditioning, blowing full power in re-circulate mode. Open all dashboard vents and ensure all windows are shut. Push the front passenger seat as far forward as it will go and tilt the back of the seat forward towards the windscreen. Place the aerosol on a small towel behind the front passenger seat in the rear foot well making sure the aerosol locking valve is positioned towards the centre of the vehicle. Depress the locking valve until it remains securely in place and the unit is discharging whilst making sure that your eyes and face are not directly above the aerosol. Exit the vehicle ensuring all the doors are closed. Wait approximately 10 minutes for the aerosol to fully discharge and for the powerful anti-bacterial agents to recirculate. Remove the empty aerosol from the foot well and wipe up any excess moisture from the back of the passenger seat and interior windows with a cloth. The moisture is harmless and will not stain upholstery or carpets.
