CarPlan Kleen Air has been specially formulated to eliminate bacteria which occur in vehicle air conditioning units. The moist atmosphere within air conditioning systems encourages the build up of micro-organisms which may cause unpleasant odours and bring on flu-like symptoms. The powerful anti-bacterial agents in Kleen Air clean and purify the air conditioning system in under 10 minutes, leaving the atmosphere in your car clean and fresh. Advantages: Kills bacteria Eliminates unpleasant odours Easy to use 10 minute application Application: 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 forward as far as it will go and tilt the back of the seat forward. The Kleen Air box can be used to keep the aerosol upright once activated. Simply push out the circular perforation and place the aerosol in the hole. This should then be placed in the rear foot well, making sure the aerosol finger tab 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 approx. 10 minutes for the aerosol to fully discharge. 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.
