I've been really interested in throat maintenance, I've watched with a bore scope as I shot a barrel out without any attention to the throat and the current one I've given the throat attention when I clean and it's maintained a much better throat and accuracy has been much more even through it's life.
I have no bore scope, but KG1 is what I use for carbon removal also because its proven so effective for me. I even use it to remove the carbon from the outside of my fired case necks prior to resizing. The carbon comes off quickly and relatively effortlessly.
Since you're employing a bore scope, when you talk about cleaning and maintaining the throat, are you primarily referring to carbon removal? Or both carbon and copper removal? I've never used a bore scope so I'm wondering what I don't know, that I should know.
By the way, without the benefit of a bore scope, I thought KG-12 was also very effective on copper removal. But not as effective as Bore Tech Eliminator's Cu++ copper removing solvent. I went through a process of cleaning my bores overkill for the application of Gun Juice (a laborious and repetitive shoot once-clean to bare steel process), and during those applications I experimented with KG-12, BTE, and BTE Cu++ extensively. I'd use KG-12 until I thought my bores were completely copper free. Then I'd apply BTE Cu++ and obtain some blue staining on my patches following the initial Cu++ application and soak period of time. That's how I've formed my opinion.
After watching the video above, I may just focus on carbon removal now with my custom after-market barrels and leave the minimal copper fouling in-place. The after-market barrels don't copper foul very much anyhow. And if I'm headed in that direction, I'd like to know what you've learned about carbon removal and throat maintenance through bore scope observations.
