It doesn’t… I’ve tried it with bore scope verification. Helps to loosen powder fouling but nothing else, certainly doesn’t touch carbon.
Thurro clean every time?

Sea Foam works like a wash…. Free-All and a bronze brush is great on carbon… scrub with Free All and let it sit awhile then scrub a bit more its pretty good. Nothing get it all except an abrasive. I have 3 barrels that grab copper.. these barrels were abrasive USE barrels.. I swear smoothing out with abrasive causes copper fouling. Use abravise very little if needed in my opinion..

Yes. Dip a bronze brush in it and give it 10-15 strokes and see all the black that comes out on a patch after that.

After reading all of this, I dragged out a AR 15 rifle the I've had in my safe from before I had a bore scope and took it out and borescoped the barrel. It had some carbon and build up where a carbon ring was forming. I got out my Bore Tech C4 carbon remover and put some on a bore mop and swabbed the chamber real good then used a Pro-Shot bore brush and spun it around a few times and all that carbon was gone. Same with the barrel using a very tight fitting bronze brush and C4. I spend a lot of time cleaning my rifles when I'm done shooting, the AR's a lot more time. So I see the value of Thurro Clean. It's much faster. But You really don't need it if you stay on top of it. And use more elbow grease. As in a tight fitting bore brush and a bore rod that does not bend.

This is after patching and bronze brushing with BoreTech Eliminator and looks clean with a bore scope. Dip a bronze brush in SeaFoam and give it 10 strokes and this is what comes out.

Of course it will turn a patch black. It will not remove carbon. I worked on a small section of carbon fouling with seafoam on a tight fitted patch with no luck, then went to a iosso brush with no luck, then a tight patch on a bronze brush and nothing changed. Maybe after years of stroking- it might have taken it out but there are things 1000 times better at removing carbon.

We all evolve on our cleaning regime over time it seems. I now am using c4 and an oversized nylon brush for the carbon ring and patch out on the barrel after each use, but eventually I just can’t help myself and use the thoro clean. Damn Borescopes! Usually every 300-400 rounds. I do now just use the thoro clean with patches only. Too many smart people on here have me convinced using a brush with an abrasive comes at a cost.
Still overthink it whenever I clean though.

I try to pay more attention to what’s happening down range. Having said that, I patch out my barrels with C4 and Clenzoil, paying particular attention to the throat / neck area , and the first 6” or so of barrel after each range session ( usually 20 or so rounds ). Abrasives and metal brushes make me nervous.

For me, I prefer using a patch with an abrasive wrapped around a parker hale jag vs putting the abrasive on a brush.
1. The brush just gets groody
2. Most of the abrasive on a brush never touches the barrel - kinda a waste.
3. I don't have to worry about Frank G's concerns.

5 seconds with a can of Brakleen over the trash can fixes that.

I usually hit it with a product called Spray Nine and a toothbrush. Cleans up quick
After PDn for a day, three guns may have 100-300 rounds apiece on 'em in a high volume day. Most I've ever shot is 350 on my Vartarg without cleaning.
I wet moly my bullets which seems to aid in keeping them shooting and CFE powders to keep copper fouling at bay.
Primary cleaning is Wipeout with Accelerator followed by Butches or Copper Killer and bronze brush and patches.
It's rare that I clean them without using Flitz on a tight patch wound around a Parker/Hale type jag as the last cleaning step followed by a rinse with Accelerator or Brake cleaner and a light oil with Marvels.
Are they spotless clean?....nope they're still a little dark in the breech end. But they're ready for another 500+ day on the prairie.

When it’s time to clean brushes and bore mops, I have a small Tupperware container I put a squirt of Dawn dish soap and half full of warm water then drop in the items, pop on the lid and give it a good shake, I let that soak overnight with another shake or so and dry on an old towel.
brushes are quite clean as well as the bore mops.
No more $5 per can of brake cleaner for me.

I have a new barrel on my 6.5 Creedmoor and now after 750 rounds I have carbon that will not come out of the scratches in the grooves in the first 12" of my barrel. Time for the Thorro Clean. Never had a problem with copper that CR10 would not remove in a couple of patches. I do notice accuracy is off with the carbon. I will not let this go so long next time. Just a heads up.

How often do you clean the barrel ? A little less aggressive “ preventive maintenance “ after each range session can keep you ahead of the carbon buildup.
