Copper fouling builds up in every barrel over time, and if you've ever fought it with an old-school ammonia solvent you know the drill: the harsh smell, the constant patch changes, and the nagging worry about how long you can leave it soaking. Bore Tech's Cu+2 Copper Remover takes a different route. This 4 oz bottle uses a patented two-step chemistry that pulls copper out quickly while staying completely barrel safe.
The way it works is genuinely clever. First, the formula oxidizes the copper fouling and reconfigures its electronic state to break it down. Then a binding agent grabs onto that loosened copper like a magnet and holds it in suspension so it can't redeposit back into your bore. Because the solvent doesn't get saturated and quit early, you get complete extraction even on barrels that see a lot of round count. Bore Tech built this stuff to keep up with the kind of copper buildup precision rifles throw at it.
Being 100% ammonia-free is the headline here. There's no dreaded ammonia smell, and since it won't etch or harm barrel steels, you can leave it soaking in the bore without watching the clock. That's a big deal for anyone who's used to babysitting a wet patch. The formula is also biodegradable, non-flammable, and non-hazardous to handle, with just a mild pine odor instead of the usual chemical punch.
The routine is simple. Run a few wet patches through in one direction to clear loose fouling, follow with a nylon brush soaked in Cu+2, let it soak a few minutes, then patch it dry until the patches come out clean. Badly fouled rifles may want a longer soak or a second pass. When you're finished, dampen one last patch with Cu+2 and run it through. That built-in short-term rust preventative shields and conditions the bore for up to two weeks of normal storage. It's made in the USA and earns its spot on plenty of benchrest and precision shooters' cleaning benches.
Yes, the Cu+2 formula is 100% ammonia-free. That means no harsh ammonia smell while you work and no risk of the solvent etching or harming your barrel steel. It's a big reason a lot of folks switch over from traditional petro-ammonia solvents.
Since it won't etch or damage barrel steels, you can leave Cu+2 to soak without watching the clock. A typical soak runs about 3 to 5 minutes, but heavily fouled rifles can sit longer with no worries. Just patch it out dry when the copper's lifted.
It does, on a short-term basis. The formula includes a built-in rust preventative, so dampening your final patch and running it through the bore shields and conditions the barrel for up to two weeks under normal storage. For long-term storage you'll still want a dedicated protectant.
For a home or range cleaning kit, the 4 oz bottle is a practical size that covers plenty of sessions since you only use a few patches and a wet brush per cleaning. If you're a high-volume precision shooter running frequent copper removal, the larger 16 oz bottle may stretch further. Either way, a little goes a long way.
