7-30. CLEANING AIRFRAME EXTERIOR AND ROTOR BLADES
CAUTION
Use care to prevent scratching of aluminum skin when cleaning
main rotor blades. Never use volatile solvents or abrasive
materials. Never apply bending loads to blades or blade tabs
during cleaning.
NOTE:
Avoid directing soapy or clean water concentrations
toward engine air intake areas and instrument static source ports.
Wash helicopter exterior, including fiberglass components and rotor
blades, when necessary, using solution of clean water and mild soap.
Clean surfaces stained with fuel or oil by wiping with soft cloth
dampened with solvent, followed by washing with clean water and
mild soap.
Rinse washed areas with water and dry with soft cloth.
7-31. CLEANING TRANSPARENT PLASTIC
CAUTION
Never attempt to dry plastic panels with cloth. To do so causes
any abrasive particles lying on plastic to scratch or dull
surface. Wiping with dry cloth also builds up an electrostatic
charge that attracts dust particles from air.
Clean outside surfaces of plastic panels by rinsing with clean water
and rubbing lightly with palm of hand.
Use mild soap and water solution or aircraft type plastic cleaner to
remove oil spots and similar residue.
After dirt is removed from surface of plastic, rinse with clean water
and let air dry or dry with soft, damp chamois.
Clean inside surfaces of plastic panels by using aircraft type plastic
cleaner and tissue quality paper wipers.
