TOW 2 Missile System . . .
Starting at the center of the lens, wipe
in a circular motion, slowly moving
outward. If a dry tissue won’t remove
all the dirt or grease, wet a fresh tissue
with alcohol and clean the lens again
with the same circular pattern. Repeat
if necessary, but always use a fresh
tissue. Otherwise, you’re just putting
dirt back on the lens.
If the lens is still dirty, fold a lens
tissue in half and then fold it in half
again. Don’t wipe the lens with the
side of the tissue you touched. That
puts oil from your skin on the lens.

One thing that all lenses have in com-
mon, though, is that you do not clean
them with rags, paper towels, shirttails,
or anything similar. Those things are
guaranteed to scratch all lenses.
To clean
day sight
lenses, first blow
off dust from the lens with the rubber
syringe that’s part of the cleaning kit.
NSNs for the items in the kit are listed
with the expendable supplies that be-
gin on Page C-2 of TM 9-1425-450-
12. Don’t use your own breath. That
puts moisture on the lens and attracts
more dirt.

arts may be parts when it comes to chicken, but lenses are not lenses when
it comes to cleaning TOW day sight and night sight lenses.
The lenses are quite different, so the procedures for cleaning each sight are
quite different. If you don’t do them right, you can damage expensive—as in
thousands of dollars—lenses.
