    Barrel Cleaners

    I have been on a quest for a few years now to find a chemical product that will lift carbon from barrels quickly and thoroughly. I believe I am getting closer. I tried Patchout a few months ago now and must say I am quite impressed with it. It is a great cleaner for Rimfire barrels and for Centerfire barrels. It doesn't, however, work as well in CF barrels as it does in Rimfire barrels.

    The directions say not to brush when using it but I don't know why. If it doesn't readily eat the base metal of the barrel, how is brushing going to harm anything? My standard practice for cleaning Rimfire barrels became soak a brush in Patchout and brush a few strokes, wait and dry patch, clean as a whistle.

    Doing the same with the barrel I am currently using on my HBR rifle, a set back barrel that has some rounds through it, some carbon remains, ( cut barrel with uneven grooves). For this I wrapped steel wool around a worn brush and stroked it a few times. Clean as a whistle! Hey, these freakin barrels wear out anyway and the rifles that shoot best when clean, why not scrub the buggers?

    May have found something better. A friend gave me a small bottle of a detergent with citric acid in it. I wanted to try it on the inside of case necks to try to find a way to quickly take the carbon out of them. Well, this one seems to do pretty well. Using Qtips to apply the detergent and to remove the residue, it is possible to take it all out. Not as quickly as I would like but it is reasonably fast acting. Dern if the stuff doesn't look, visually, a lot like Patchout .

    I am trying to find a larger scale process so that each case doesn't be handled several times but that should present itself soon. I do not see any reason why this detergent would not work equally as well as the Patchout or it's variants. The Detergent does etch the brass where as the Patchout doesn't. I don't really care if the brass gets etched and guess It isn't a big issue to me with the barrels either, at this point. BUT, we have something that is workin!

    Get one of those bore mops a size or 2 over the case neck diameter and add a few drops of the cleaner to it and chuck it up in an electric drill and run the patch into the case and see how long it takes to clean it. If I was doing a lot of them I'd clamp the drill in a vise making sure that I have access to the trigger and button that lets it keep running. Bore mops can be cleaned by rubbing a few drops of detergent into them and rinsing well with warm water and air drying. You'd maybe want to buy them in bulk. I use them for swabbing rifle chambers and cleaning the bolt lug raceways.

    Patchout is quite popular. Everybody I've seen, including myself, brushes it with a bronze brush, which it will eat unless you swirl it around in a bottle of water [water soluble]. Use the liquid with accelerator.
    Thoroughclean from Bullet Central is gaining traction as well....RF & CF.. it is IOSSO in solution with a flushing liquid.

    I have been using JB Bore Cleaner for Carbon going on 50 years now. But as you say if one doesn't stay on top of it Carbon can become very difficult to try and remove.

    For hunting rifles some say as long as it shoots [I assume sub MOA or when the groups start to open up] that they don't clean which could mean several hundred rounds. How many rounds on average is it necessary to clean to prevent carbon buildup? 20? 50? more?

    is a subjective thing. In the case of Score shooters, it depends on how big the x is as to how accurate one needs their rifle to be. Most Benchrest barrels need to be reasonably clean to hit tiny dots. A few barrels like to shoot dirty but there are more that like to be clean. So, comparing folks who need to hit 1/6" dots to folks who only need to hit targets in the inches size is an exercise in futility. We talking 1/16 th of an MOA here.
