ATTN: CLR users...

What about a 50/50 solution of vinegar and water basically the same thing some people use to clean brass or brakes in an ultrasonic cleaner as soon as you drop brass or a brake in the carbon starts coming off
 
On 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.

Rub the bore tech products between your fingers. They use a surfactant just like soap works
 
But 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 no worry about messing up stock finish or bluing
 
Soaked another stub from a top maker. CLR did nothing to it. Same type of SS.

So goes to show it depends on what lot, who made the steel and what ingredients are in it. An Alloy test see what percentage is what in the steel might shed more light onto this. Out of curiosity, I will shoot each one and get a make up of both.

Regardless, use at your own risk, lol
 
I just used CLR for the first time and I'm sold! I won't ever waste my time or money on "bore cleaner" ever again. I also used Montana X-Treme copper solvent for the first time and I was happy with that as well.
 
Are y’all talking about CLP or CLR?

As far as I know, CLP (“Cleaner Lubricant Preservative”) is pretty harmless and has been used a lot by the military.

CLR (“Calcium Lime Rust”) is pretty harsh and yeah I wouldn’t want to leave it in contact with gun metal.

OK, here is the elements in each stub, a sporter and HV. Just to recap, the sporter stub was etched and the HV didn't seem to be affected by CLR. I let the sporter stub in a week and seemed to develop pin hole pits. I didn't penetrate test it, just visual. I may PT it yet.

Sporter make up:
410-416 SS
Cr=11.85
Mn=.654
Fe=86.54
Ni=.588
Mo=.364

HV makeup:
410-416 SS
Cr=11.74
Fe=86.88
Ni=.445
Mo=.318

Im no metalurgist, just providing some unbiased info.
 
I 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.
