I was looking for a way to get that stubborn carbon out of the inside of the bolt carrier that builds up behind the gas rings and on the bolt behind the gas rings that normally would have to be scraped off. I come across this mixture and I was curious if anyone has used this. I bought the supplies needed and I will give it a try next outing.

QUIB'S ODORLESS MINERAL SPIRITS/CLP BOLT CLEANING PROCEDURE

Reason being that I want to avoid constantly scraping is that I do not know the long term effects on the chrome lining inside my bolt carrier.

My friend uses carburetor cleaner. Not sure if that's advisable or not, but I have seen firsthand what it can do, and it's pretty awesome.

I currently use brake cleaner and it works to an extent. I haven't noticed any ill effects on the metal parts but it does strip all the oil out of the metal. It does however mess with anything plastic. I will continue to use brake cleaner to clean inside the barrel, gas tube, and inside the receiver. I spray the brake cleaner down the barrel then followed by Hoppes #9 followed by a CLP soaked patch and it comes out spotless.

In the category of "probably don't want to do that" solutions: loooong ago, we would soak the gas piston overnight in Coca-Cola. Not sure though if the "new" coke formula works as well.

I've heard that you can leave a tooth in a newly opened can of coke, and it will be completely dissolved in a week. Don't know if that is true or not, but I would bet that it would remove carbon.

I've always used regular CLP on an AR bolt and it gets it clean.

I use brake cleaner as well. I shoot my RRA AR weekly at training, and cleaning it has become a ritual. The carbon scraping was a worry for me also. I was advised by a few of the folks from some major manufactures that brake cleaner would work just fine, and then use your brush to get the rest off. Make sure you lube correctly afterwards and your GTG. Like I said this was passed on to me. Seems to work, I have fired quite a bit of rounds and zero problems out of my RRA entry tac....HTH ...

Also I have a new M4 that I have decided to enroll as an acolyte into the froglube temple just to see how things go. Bolt and carrier swathed in the 'squeezeable' froglube, all other metal on metal poinits "painted" with the paste. It is not supposed to totally stop carbon deposits but is supposed to inhibit it's ready want to bake itself on and thus make it a tedious chore to clean. Admittedly I have not shot this one enough to lend a report so cant offer a worthy report.

I continue to be tempted by gas piston rifles because of this. Nothing wrong with DI but I freely admit to being a lazy ass and want an easy life!

Give that carbon killer a try tho and report your experience with it.

After years of shooting thousands of rounds thru various AR platforms, I've found a little bit of carbon discoloration is NOT a problem. I keep my bolts/carriers clean enough with Hoppes and clp to eliminate any thicker deposits and take down the bolt/carrier after every range session so it doesn't cook into the bolt.
If you're really crazy..Flitz polishes out most discoloration, but I don't think its' necessary.
I think we often get waaay too anal when it comes to excessive cleaning..and it can potentially do more damage and expose us to harsh chemicals/fumes than we really need to use...imho.

Kenny D · 06-23-2012, 06:47 PM

The carbon I am referring to is a build up at the back of my bolt carrier and in the groove that is in line with the hole underneath my gas key. After shooting a hundred or so rounds I end up with a significant amount of baked on carbon that doesn't wash off with hoppes or brake cleaner. It has to be scrapped off and comes off in chuncks. 99% of my ammo has been Federal. Either XM855, XM193, or Federal American Eagle AR223. That's why I'm going to give this soaking mixture a try.

In the Marine Corps, we used this trick to get that BCG carbon out. Take three USGI cleaning rods all oriented the same way and hold them in a bundle like you would a bunch of straws. Insert it into the hole, and twist about. It should get the carbon out and not damage anything.

I'd be tempted to try some "bug Juice" from the navy if i could score some. we used it to get verdigris off brass fire nozzles and it worked like a champ

In SEA 1965 the jet turbine oil worked dandy.Kinda hard for the average civilian to come across it though. The oil kept the stuff sorta soft.Easy off oven cleaner works also but you will need a hot soapy water wash out and a super re oil.Try lubing with mil tec and heat it in with a heat gun or hair drier. That will keep most of the carbon from sticking and works wonders on my sig pistols. Keep oven cleaner off the plastic and woods.
