While cleaning some MK18/M4A1 hybrids, I got some CLP on the pistol grip. A Gunners Mate Seaman scolded me for getting CLP on the pistol grip because he said it corrodes plastic. I responded by saying that I have used CLP on my personal AR for a couple years now and have never heard of that problem. He told me he didn't go to A-school for nothing.

Who is right?

I've had plastic and rubber covered in clp for years and I've never seen any problems. I use m-pro7, which they claim is non-toxic.

Were you using Breakfree? I've never heard of any problems from that either.

Yeah, the government is going to give cleaning agents that will destroy plastic to joes..... Your guy got bad info from someone he trusted and now he is spouting it as gospel.

My Drill Sergeant did the same thing about how the bullet rises when it leaves the barrel and that is why it hits the same point at 25 and 300 meters. We know that is the gods honest truth right? Of course I couldn't keep my damn mouth shut and got smoked while he went and asked someone who knew. Then he smoked me more for being right.

I've heard folks say that but it gives me pause since the CLP is in fact often in a plastic bottle to begin with.

Yea, the Navy.  The same organization that will have sailors cleaning brass with Tabasco sauce and steel wool when they sell brasso in the C-store.


I still remember some poor wookie cleaning a capstan.  Asked her if she had brasso "They said this works better".  Brought down my brasso, BOOM done in 2-3 minutes (she got maybe 6x6" square done in 30 minutes).  "Don't believe everything you hear".

But it will remove the "decal" type or film  camo coating that is on some of the newer shotguns. Ask me how I know.

The problem may be worse than just an idiot spouting stuff "he heard."  Is the gunners mate in a position to enforce his prejudices?  If so HIS boss needs to know what he's saying and what the manual says.  "Going to A school" does NOT trump what the manual says, and doesn't the manual (it's the same one for all 4 branches) say that CLP is the standard cleaner/protectant/lubricant?  Why yes, it does: pg 16 of TM 9-1005-319-10 directs the use of CLP for cleaning the rifle.  Further, there is NO warning about not getting CPL on the polymer components of the rifle.  If you needed to "go to A school" for this important information, wouldn't it be printed in the manual too?

Blowhards and vocal idiots NEED to be corrected; otherwise they keep spouting their falsehoods and screw up other people.

It will in fact eat some plastics.  I had some parts that I placed in a Lee Reloading Die case (the transparent red ones) and sprayed them down with clp, next morning the plastic was visibly eaten by the CLP.

Not wanting to start a fight here, but spent several years working in a chemical plant. Was the case affected by the CLP, or the propellant that got the CLP out of the can?
Some propellants ARE toxic to plastics, even tho the product itself isn't. JMHO, and I'm sticking to it. Thanks, Mike

according to the MSDS for CLP, it is in fact non reactive and as such will not harm plastics.  as already stated it was most likely the propellant that caused the issue. btw why would a reloading company use a polymer that has issue with one of the most prolific lubricants/cleaners out there?

GM "A" school is how long?

Ask him since he referenced his "A" School training, that "corrodes plastic" should be a caution or a note in his Navy Publications set. First, address him appropriately with the opener: "SHIPMATE"...remember, don't yell, be respectful, but exert stern voice inflection when you "ship-mate" him. Next, tell him to show you "in-the-pub" in writing, or a TPDR submission regarding the pending change to the pub. If he can't, then congrats, you were smarter than the Seaman.

I had to laugh on that one - the same crap the DI told us in Basic in 1966. He even drew a horizontal barrel with the bullet trajectory leaving the muzzle at an up angle and curving away. Even then I knew it was ignorance but I did manage to keep my mouth shut.

That Gunner's Mate is an certified assclown - like someone said, ask him why CLP is sold in plastic bottles?

I have sloshed it all over various fireamrs with different plastic and polymers and never seen one hint of a problem.

A veteran friend of mine was taught similar nonsense while in the service.  He once told me that the bullet initially falls from the muzzle and then "once it picks up speed, it turns and flies upward."  After I pointed out the height of the sights above the bore-line and showed him a few trajectory graphs and velocity tables, you could see the light bulb go on in his head.  He then muttered, "Why did they teach us such stupid shit?"

Not sure exactly what you mean by this comment. Near as I can tell there are hundreds of folks on these forums trying to replicate Navy weapons.  I'm guessing that because someone is in the Navy they musn't know anything about firearms, does this sound about right to you?

I would go a different direction on this.  I'd say that maybe the Sailors rank has more to do with it than his service choice.  

I'm guessing that since I'm just a Navy Corpsman I prolly don't have any idea what it's "REALLY" like in the military huh?

Take a look at my avatar and re-think your position killer.  I'm certain a course correction is needed here.

ETA:  Just so my position is clear, this Sailor is a dumbass.  But I would imagine he is only saying some shit that another dumbass told him.

Im not sure about Breakfree CLP ,But BreakFree Powderblast will EAT PLASTIC  and RUBBER for lunch. Read the side of the can. It was made to remove damage from plastic cartridge cases. Or some other nonsense. But I can tell you when it pools it will eat rubber. I had a rubber mat on the table and sprayed over it and the Powederblast remained in a small pool and actually pulled the rubber together making a "bubble". I think maybe this is where a lot of the confusion comes from.Kinda like saying all coke products are bad when truly only the diet sucks .

The only mil used substance I've heard issues with was the dry cleaning solvent used in armory parts cleaning tanks/sinks. We were permitted to use them on a couple of occasions in SOI, but were told DO NOT get the solvent on plastic parts. Basically lowers were a no-go.

I would, but Midshipmen are considered nothing compared to a Seaman in Navy World.

My reaction was , but I didn't feel like arguing. I should have expected this since half of the GMs couldn't remember how to field strip and assemble an AR either. I, the lowly Midshipman had to help them out with it.

Just the other day I was replacing the spring in my ZT0302 knife. While apart I decided to clean and lube it using Break Free CLP as that was all I had avaliable.

I used my Benchmade tool kit with his a clear plastic cover. CLP from my hands got on the clear plastic and made it hazy and sticky. The blue plastic was fine. Different compositions I suppose.

I remember back in the late 80`s there was a big deal about BF CLP and teflon and the Military .
Dont know wich branch?

I think Thats one reason Pat R uses Slip 2000!

Ive used BF for many many many years havent  had any problems.
And the Plastic insert is Fine

Yeah, I definitely wouldn't worry about using it on your service weapon (or any gun for that matter).  Remember that not all "plastics" or things that are often refered to as "plastics" act the same when they come into contact with a given solvent / chemical / etc...  Each has their own individual chemistry.  CLP might eat polycarbonite or plexiglass (poly(methyl methacrylate)), but that doesn't mean it's going to eat your grip.
