JP-8 does a great job cleaning off carbon.
Not really. Any JP-8 remaining on the
weapon will actually cause worse carbon buildup–and it’s difficult to get off all JP-
8. The best way to prevent carbon buildup in gas systems on machine guns is to
change barrels when you’re supposed to. If you keep firing and firing the same bar-
rel, carbon will soon plug up the gas system.
CLP and your cleaning tools should usually get rid of carbon. Of course, don’t use
CLP on machine gun gas systems. Those you clean with the scraper. Lube in the gas
system causes more carbon.
If you can’t get off all carbon, your armorer can use cleaning compound solvent,
NSN 6850-01-474-2319, for tough cleaning jobs. But remember the weapon must
then be re-lubed. Solvent washes away lube.

Small Arms…
Shooting Down Rumors
R
umors about better ways to take care of your rifle, pistol or machine gun just don’t
seem to want to die. PS still hears reports of soldiers using lubricants and cleaners
on their weapons that they’ve heard are better than what the operator TMs prescribe.
Motor oil or a graphite-based lubricant works better
than CLP.
No way! Motor oil hardens and makes a mess of
your weapon. Graphite will actually eat up and destroy alu-
minum and other alloys. You don’t need that kind of help. Use
CLP, LSA-T or LAW for lubing. The Army has tested them
and has confidence that they will do the best job helping your
weapon do its best job.
