What's the best solvent to remove copper fouling??

[gohring3006]

I use Gunslick bore foam.
I don't decopper as much as I used to since going with Hex boron nitride coating. I usually decopper about 300 rounds or so, and Gunslick will get the copper out. It might take a couple of of applications, but it works for me.

I like KG 12 because it's ammonia free and you don't have to neutralize it.

Ammonia.

Wipe-out works good for me. I use the accelerator with it most of the time. They also make a product called carb-out that works better than anything else I have tried for carbon.

For stubborn build up I like Bore-Tech CU+2 Copper solvent, and Pro Shot copper solvent. I prefer these chelating based copper solvents over the ammonia based solvents. For general cleaning of my barrels that have mild copper build up, Bore-Tech Elliminator is my favorite.

I use KG12 if I want to get it out quick and wipeout if I have time to let it sit over night.

I use a piece of tubing that fits my chamber so I can spray cleaner in with the barrel pointed down to really soak it. Pretty much much any solvent works that way if you let it sit after a dousing for 10 minuets or so. PB Blaster is great. Usually 5-6 patches after that and I'm done. Bore scope tells me it works.

PB Blaster that's a new one. I have that in the garage will have to try it. I can pick that up at parts store anywhere if it works

PB Blaster also works really well on carbon buildup in the throat and bore.

JB Bore paste, Iosso or JB Bore Bright for tough copper. I start with Wipe Out or Butchs Bore Shine for the powder residue and then see whats left. If there is copper in the lands I use one of the above.

I use Pro-Shot Copper Solvent IV. Works great for me. I've cleaned some NASTY barrels (belonging to friends and family) with it. Some of which were rusted and crusty...But they cleaned up (after alot of work) back to a mirror finish.

Another vote for KG12. Accuracy International suggests it also

Like it says, what I'd the best for the copper. I've used Montana copper killer didn't seem that great. I've used sweet 7.62 seemed better at cleaning carbon and of coarse hoppes #9 which works alright. I've also used shoothers choice and didnt care for it a ton. What have you guys had luck with?

wow, that's like "what's the best rifle round", the BEST copper cleaner is the one that works best for YOU; how often you clean, how you clean, what results your happy with, etc. i think ALL the cleaners work, just some work better for your particular regiment/methods.

BoreTech Eliminator. It's not magic in the sense that one patch will get everything out the first time but it works very well on copper and other fouling.

Don't understand the fidelity to Hoppes.
