So, I have treated my Glock 19 as well as a couple AR15's with Fire Clean and I have to say it does work wonders on carbon. I still use a bore cleaner (I like MPro-7 or Otis brand), though. I went shooting today and shot quite a bit. Speer Lawman 124gr 9mm. Here are some photos:
Just disassembled the weapon and yes that is a bit of carbon.
I see carbon. Also, I can see where the bullet nose hits the feed ramp on chambering
This is after wiping with a paper towel. No brushes yet. You can see it did a good job just with wiping. I did later use a brush and Q-tips to clean the deeper nooks.
Again, lots of carbon.
And, again, just wiping it off with a paper towel.
Now, this is not to say that all you need to do is wipe it down and you're good. I still needed to use Q-tips and a nylon brush to clean the slide and frame, but it took 1/4 of the time to do so since the carbon just wiped away.
Supposedly it treats the surfaces making subsequent cleanings easier. Time will tell.
Train hard and train often.
