•
Thoroughly clean and degrease the weapon.
•
Thoroughly dry the weapon.
•
Apply an even coating of SFL to the areas that
need touchup.
•
Allow the SFL to fully cure for 24 hours before
returning the weapon to service.
See the weapon’s -23&P for the limits on how much of the weapon can be touched
up with SFL.
NSN 9150-01-260-2534 brings a 16-oz aerosol can of SFL. You can also get a 1-
qt can with NSN 9150-01-360-1908 and a 1-gal can with NSN 9150-00-142-9361.
These are non-aerosol and must be applied with a brush, which will produce a more
even application than spraying on SFL. Whichever kind of SFL you use, carefully
follow the instructions on the can for best results.
Applying SFL
If you need to degrease a weapon
in order to touch it up with solid ±lm
lubricant (SFL), use MIL-PRF-680
Type II dry cleaning solvent. It’s
not enough to let the weapon’s parts
soak in the solvent. You also need to
scrub the parts with the solvent and
a non-metallic brush to clean out all
dirt and grease.
The Army doesn’t recommend a speci±c cleaning tank. But you should
never
use
an ultrasonic cleaning system. They can completely remove a weapon’s protective
coating, which leaves the weapon defenseless against corrosion.
You should also
never
use a
water-based cleaning fluid. That
leads to corrosion.
Use only the cleaning materials
listed in the back of the weapons’
-23&P TMs. These cleaners have
been tested and approved by the
Army. MIL-PRF-680 Type II dry
cleaning solvent, NSN 6850-01-474-
2317, is authorized by the Army.
Do not clean several weapons at once in a cleaning tank. It’s too easy to mix up
bolts and receivers, which would ruin headspacing.

cleaning small arms in
cleaning tanks is ok, if
done correctly.

cleaning tanks can turn a
