I have never seen green colour on any patch so I dont think its coming out.
Whats a good solvent?
Most of all is it right to see copper colour in the rifling, and I have used a nylon and brass brushes.
The green colour is a reaction between the copper and solvent. You won't see it with all so that's nothing to worry about.
If you can see copper still obviously it's not gone. How long are you leaving the solvent in for you?
Do you just patch it through, scrub it and patch it out straight away?
For stubborn fouling try run a wet patch through, give it a scrub with a nylon brush to agitate the solvent and leave it for 15 minutes. Patch it out with a few dry patches and see how it looks. Try a repeat or two until the dry patch comes out basically clean and you should hopefully find the fouling is gone.
The solvent should be doing the majority of the work for you. You're not trying to physically scrape it clean with the brass brush.
