Windscreen and Windows
Before cleaning an acrylic window, rinse away all dirt particles before
applying cloth or chamois. Never rub dry acrylic. Dull or scratched
window coverings may be polished using a special acrylic polishing
paste.
• Caution •
Clean acrylic windows with a solvent free, none abrasive,
antistatic acrylic cleaner. Do not use gasoline, alcohol,
benzene, carbon tetrachloride, thinner, acetone, or glass
window cleaning sprays.
Use only a nonabrasive cotton cloth or genuine chamois to
clean acrylic windows. Paper towel or newspaper are highly
abrasive and will cause hairline scratches.
1. Remove grease or oil using a soft cloth saturated with kerosene
then rinse with clean, fresh water.
• Note •
Wiping with a circular motion can cause glare rings. Use an up
and down wiping motion 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 contaminates.
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 nonabrasive 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 requires
only occasional cleaning with mild liquid soap and water or isopropyl
alcohol, and a soft cloth.
• Caution •
If a EVS Sensor Window breaks, use gloves and masks when
handling broken germanium window material.
