    I have the thunderbeast 338ba that I use on my 308 quite often.

    The muzzle break itself has a ton of caked on carbon, with the most on its front face. I've tried to use my regular cleaning stuff and even a bronze brush and its really baked on there. What can I use to clean it off?

    Do I even need to clean it off? I don't think it is affecting accuracy at all.
     
    Saw a pic of a guy who hung his rifle from a rafter so the break sat perfectly vertical in an ultrasonic cleaning vat. I removed mine and used an ultrasonic cleaner for great results.
     
    Ultrasonic cleaner will do the trick. I use MPro 7 in mine and it works great.

    New to the forum but here are my recommendations for removing carbon build up. Many years ago with carburetors on most small block V8's (before the days of port fuel injection) to clean the carbon and gunk off of the intake and intake valves one would allow the engine to warm to operating temp and then intravenously feed cold water droplets to the intake to break apart the deposits.

    I recommend using a butane torch to heat the brake or FH to the point where it's NOT glowing red but enough to mirror a moderate string of fire and then quickly administer a cool mist of water. A couple of attempts should suffice along with a brass brush will break everything up nicely for those with out an ultrasonic cleaner.

    Edit: please make sure to wear proper eye protection before attempting.

    Good idea in the ultrasonic cleaner. I don't want to take the actual brake off so I'll just set the end off the barrel in it. A couple quick questions about that.

    1.will this take off the black color on the brake? I know ultrasonic cleaner has raven off the coating of some of my other gun parts.

    2.what formula do you guys use for go parts, my formula is for brass. Exact ratios would be nice.
     
    I read somewhere on here to use boiling antifreeze. I know this works on busted cylinder heads as they come out crystal clean when I blow a head gasket, other cylinders have carbon on exhaust valves
    I'm just looking to buy a small stove to do this in the garage with rifle inverted

    I'll let you know how it works this Friday !!!

    Boil it in antifreeze. Doesn't harm finishes and it'll be squeaky clean in no time.

    This an old timer trick from model RC planes for getting engines cleaned up that have become caked and gummed full of varnished castor oil and nitro.

    works really well.

    I have a 30BA brake on my 308. i didnt have much carbon buildup but after shooting a few hundred rounds suppressed, there was some build-up and a seafoam green color on the front face of the brake. i never really clean the gun much and had no reason to worry about the buildup on the face of the brake.... right? Well, after a few months i had an oily rag out one day and i wiped down the brake that had the carbon and green build-up. Low and behold, whatever it was had chewed through the brake finish and etched onto the brake metal. it looked like it had been attacked by rust for a few years, on the front face of the brake.

    All rounds were factory FGMM, i live in a very dry, non-corrosive environment, the rest of the gun is cerakoted black, but the brake was just like it came to me from TBAC. it doesnt really bother me because its purely cosmetic, but i found it odd that that would happen with such a low round count with commercial, American ammo. Just a heads up to some.
     
    For ultrasonic run 50/50 water and white vinegar for 24mins, then a tea spoon dish soap for 7-8 mins to neutralise the acidic vinegar. Finally another 7-8 mins clean water. Will take all the carbon off.
     
    Had a carbon build-up on the muzzle of my 300 whisper. Shot it year without doing anything bout it. The build-up got thicker with time, so time to do some thing about it. It was a very hard substance almost like it would require a hammer and chisel to remove. Tried some polishing compound that is used with a Dremel tool, available in the Dremel section at your local hardware. Dabbed some on a cloth and started scrubbing. Worked great, came off in no time. To avoid future build-up like that I try and clean the muzzle after every shooting session with normal gun cleaners like Birchwood Casey, MPro7 ect.
