To Clean Exterior Windshield and Windows

rinse with clean, fresh water.

Wiping with a circular motion can cause glare rings. Use an up
and down wiping motion on the windshield in the direction of the
airflow to prevent this.
To prevent scratching from dirt that has accumulated on the
cloth, fold cloth to expose a clean area after each pass.
2.
Using a moist cloth or chamois, gently wipe the windows clean of all
contaminants.
3.
Apply acrylic cleaner to one area at a time, then wipe away with a soft,
cotton cloth.
4.
Dry the windows using a dry non-abrasive cotton cloth or chamois.
Enhanced Vision System Sensor Windows (Optional)
The Enhanced Vision System Sensor is located on the underside of the LH
wing. The three sensor windows are made of Germanium. In contrast to
visible light energy, infrared energy typically passes through dirt on the
window. As such, the Sensor windows require only occasional cleaning.
• CAUTION •
If an EVS Sensor Window breaks, use gloves and masks when
handling broken germanium window material.
Do not use abrasive cleansers or cleaning pads on the germanium
window. Abrasive cleaning can damage the sensor window
coating.
Do not use any cleansers containing ammonia. Ammonia will
remove the sensor window coating.
To Clean EVS Sensor Windows
1.
Apply mild liquid soap and water or isopropyl alcohol, then wipe away
with a soft, cotton cloth.
2.
Dry the sensor windows using a dry non-abrasive cotton cloth.
Engine Compartment
Before cleaning the engine compartment, place a strip of tape on the
magneto vents to prevent any solvent from entering these units.
