As I was told as a kid, "if so-and-so told you to stick your head in the oven...."
Rub the bore tech products between your fingers. They use a surfactant just like soap worksOn a previous carbon thread a fellow said he uses soap and water. I had often had the thought but never tried it. I put water and about 2 drops of Dawn dish detergent in a small squeeze bottle. Not the do all end all but 6 or 8 patches well soaked will get a very large amount of the carbon out for almost no money compared to the 25.00 or more a bottle chemical. Follow up with a patch or two of Montana Extreme soaked over night gets what remains. About every 200 rounds a bit of Iosso keeps them shooting small, which is the end game.
And no worry about messing up stock finish or bluingBut the Dawn is not sticky. I believe Bore Tech and Sweets both have some type of soap in them. Plus, hard to beat 2 drops of Dawn in 4 oz of water price wise. Walked into a gun shop yesterday who had the large bottles of Bore Tech @ 35.95.
And the Gun shops will soon have Dawn on there shelves.
if he was your smith you would not need an appointment lolI pulled my short range 6mm barrel (SS Krieger) off the other day to swap for the long range (despite having no long range, uh, range, to shoot at.) Got the SR cleaned up pretty well, but the scope showed some carbon at the throat. Tried the usual methods: soak with C4 then brush, spin a brass brush, felt pellets with Iosso, nothing was really working well. Put a fresh felt pellet on with a couple of drops of CLR and and it in til I felt resistance (which I took to be at the front of the chamber, butted up against the rifling.) I got distracted and left it longer than I wanted to (ended up being about an hour, I think); when I got back to it, I gave the pellet about a dozen spins and removed it, ran a couple of solvent patches to flush out the CLR then a couple of dry patches before scoping it. Really surprised: the ring was completely gone. Totally spotless in the front of the chamber. Didn't see any evidence of anything else untoward (not that it would matter much - that barrel just passed 5000 rounds, is coppering up pretty badly, and is starting to open groups up a bit. Which reminds me that I should call my smith and see what his workload is like...)
Anyway, it works for me.

he must be goodWell, I see your point, but he's largely a competition smith, and I'm just a lowly recreational shooter.
