Copper fouling is the silent enemy of rifle accuracy. Every shot from a high-velocity, jacketed bullet leaves microscopic copper deposits inside your bore—buildup that degrades precision and can be a real pain to remove with standard cleaners. Bore Tech Cu+2 Copper Remover is a 4 oz advanced cleaning solution designed to break down and dissolve copper fouling fast, without the harsh ammonia or petroleum-based solvents found in older formulas. Whether you're running a hunting rifle, competition gun, or precision shooter, Cu+2 gets the job done so you can focus on what matters: consistent, accurate shots.
What sets Cu+2 apart is its enhanced binding agent—think of it as a magnet for dissolved copper. Instead of copper particles just floating around and re-depositing elsewhere in your bore, this formula attracts and suspends them so they rinse away completely. The result is a genuinely clean bore, not just a temporarily masked one. Over time, repeated use actually conditions the bore to help resist future copper buildup, giving you fewer cleaning cycles down the road and extending the life of your barrel.
Bore Tech formulated Cu+2 to be environmentally responsible without sacrificing performance. It's ammonia-free, non-hazardous, biodegradable, odorless, and petroleum-free—safe for you to use in any space and safe for the planet. The formula works equally well on steel, stainless steel, and lined barrels, so whether your rifle is a workhorse factory gun or a custom precision build, Cu+2 won't damage the metal. As a bonus, it provides rust-preventative protection, shielding bare metal from corrosion between cleaning sessions.
| Product Name | Bore Tech Cu+2 Copper Remover |
| Size | 4 oz |
| Type | Advanced Copper Fouling Solvent |
| Formula | Ammonia-free, non-hazardous, biodegradable |
| Barrel Compatibility | Steel, stainless steel, and lined barrels |
No. Cu+2 is safe for use on steel, stainless steel, and lined barrels. The non-hazardous, ammonia-free formula is designed specifically to clean without harming barrel steel.
That depends on your shooting volume and the fouling you observe. Repeated use of Cu+2 actually conditions the bore to help prevent future copper buildup, so the more you use it as part of your regular cleaning routine, the less aggressive fouling you'll encounter over time.
Yes. Cu+2 is non-hazardous, biodegradable, odorless, and petroleum-free, making it safe to use in any indoor or outdoor space and responsible to dispose of according to local guidelines.
Cu+2 features an enhanced binding agent that works like a magnet to attract dissolved copper, keeping it suspended and preventing re-deposition inside the bore. This ensures complete copper removal, not just temporary masking, and the formula also provides rust-preventative protection between cleaning sessions.
