M1114 Up-Armored HMMWVs
Cleaning the windows on the M1114 Up-Armor
HMMWV is a whole new can of worms. That’s
because the interior surface of the M1114’s ballistic
glass has a self-healing layer.
The only way to clean the glass is like so:
•
Remove dust and loose abrasive particles using
clean, filtered air at 20 psi.
•
Wash the interior windows with mild detergent
and warm water. Dry the windows with a clean, soft
lint-free cloth.
•
Remove stubborn marks and stains with a clean,
soft lint-free cloth and equal parts of isopropyl or
ethanol alcohol and water.
Windows on Other HMMWVs
Cleaning the windows on earlier models of HMMWVs is easier, but you still have
to take care how you clean.
Follow this procedure for plastic door windows:
•
Wash it with detergent and water, using a soft, clean cloth.
•
Apply hand cleaner, NSN 8520-00-782-3509, with a clean soft cloth or sponge.
•
Wipe off the cleaner immediately with a dry cloth.
Follow this procedure for ballistic windows:
•
Clean the outside of ballistic windows the same way you clean plain glass. The
inside surface is a plastic laminate that takes special care. Wash only when the glass
is cool.
•
Add detergent, NSN 7930-00-282-9699, to a gallon of water using the directions
on the bottle.
•
Saturate a soft cloth with the solution and lightly rub the window surface.
•
Lightly rinse off the cleaner with water and dry with a soft cloth. Do not scrub.
•
Apply polish, NSN 7930-00-935-3794, and let dry. Wipe clean.
Bug Spray, Solvents a No-No
The
propellant
inside cans of bug
spray, spray cleaners
and paint can crack the
glass. They, and liquid
solvents, are murder
on the plastic surfaces
of ballistic glass. So
keep them away from
your windows!

HMMWVs…
Cleaning
Ballistic
Windows
clean your
glass
right…
…so it
can do
this!
Here’s what you
need to know about
cleaning—and about
the problems created
by bug sprays, spray
solvents and spray
cleaners.
Last but not
least, remember
not to use scrap-
ers or any object
that damage the
window’s inside
surface. Do not
apply stickers,
labels, solvents
or
abrasive
materials to the
glass.
Maintaining and
cleaning the ballistic
windows on HMMWVs
has always been a
challenge,
but the
windows on the
up-armored M1114s
require even
more
attention
to detail.
stickers are
unsafe
for
so many
reasons!
