Many soldiers
are
not
aware of
this,
especially
in
the aviation world.
± When±
cleaning±
your±
aircraft,±
never
±
use±
industrial± cleaners,± detergents± and± degreasers±
(including± Simple± Green
®
)± that± the± Army± hasn’t±
tested±and±approved.
± Some± unapproved± cleaners± have± a± “citrus”±
compound±called±“D-Limonene.”±These±commercial±
cleaners±did±not±pass±Army±performance±tests±and±
should±not±be±used.±These±cleaners±cause±corrosion±

that±reduces±strength±in±steel,±makes±alloys±brittle,±
degrades± canopy± transparencies,± and± damages±
painted±surfaces±and±cadmium±plating.
± If± you’ve± used± unapproved± cleaners± on± your±
bird,±lots±of±fresh±water±and±an±approved±Army±
± cleaning±agent±will±get±the±stuff±off.±
± Check±your±airframe±TMs±for±approved±cleaners.±Follow±up±cleaning±with±a±corrosion±

it’s
not
a good idea to
use high-pressure water
to blast grime away from
your bird’s exterior.
Neither is it
good to use
unauthorized
cleaners.
ahh,
I’ll
just use
this stuff
we got at
the px.

that’s a
lot
of
suds…
whoa!

just
any
old cleaner
on your helicopter! it’s
gotta be
approved!
how do
I find out
what’s ok?
