Copper fouling sneaks up on you. After a heavy range day or a long season chasing accuracy, that thin layer of jacket material builds up in your rifling and starts eating into your groups. Hoppe's Black Copper Cleaner is made to strip that fouling out without a ton of elbow grease, and it does it on just about any bore you point it at.
This is a dedicated copper remover, not an all-in-one bore solvent trying to juggle every job at once. The formula uses 2-Butoxyethanol and Monoethanolamine to break down copper deposits, and it reacts with the fouling as it works. A lot of folks notice the patches coming out with that telltale blue tint, which is the copper lifting off the steel. Give it a few minutes to soak, run a nylon brush through, then chase it with clean patches until they come out white. That's the whole drill.
This bottle is step two of the Hoppe's Black five step cleaning system. You'd typically run the Hoppe's Black gun cleaner first to knock out carbon, then follow with this copper cleaner to deal with the metal fouling left behind. That said, you don't have to buy into the whole lineup to get use out of it. It works fine as a standalone copper remover in any cleaning kit you already run.
Hoppe's built the Black line around modern sporting rifles and high round count guns, but it plays nice with hunting rifles, handguns, and shotgun bores too. The 4oz bottle is compact enough to live in a range bag or cleaning box without taking up real estate, and it's made in the USA. It handles a wide temperature range, so it won't quit on you whether you're cleaning in a cold garage or a hot truck bed. For anyone shooting jacketed ammo regularly, having a real copper solvent on hand makes a noticeable difference come the next range trip.
Run a wet patch or wet nylon brush through the bore and let it sit for a few minutes so the solvent can react with the copper. Follow up with more wet patches until they come out clean with no blue tint, which tells you the copper is gone. A nylon brush works better than a bronze one here since bronze can throw a false blue reading.
Yes, it's built to be used on any firearm bore, from AR-style rifles to hunting rifles, handguns, and shotguns. Hoppe's designed the Black line with high round count modern sporting rifles in mind, but it works across the board. It's fine to leave in the bore for extended soak times without harming the barrel.
Hoppe's No. 9 is a general purpose bore cleaner that tackles a bit of everything, while the Black Copper Cleaner is a dedicated copper remover with a stronger formula for jacket fouling. If you shoot a lot of copper-jacketed ammo and see accuracy fall off, this dedicated solvent pulls out buildup that a general cleaner struggles with.
It's step two of the five step Hoppe's Black cleaning process. You'd typically use the Hoppe's Black gun cleaner first to remove carbon, then follow with this copper cleaner. You can absolutely use it on its own though, since it works fine alongside whatever cleaning gear you already own.
