Bore Tech CU+2 Copper Remover is a high-performance copper-fouling solvent engineered to dissolve and lift copper residue quickly and safely from firearm bores.
The Bore Tech CU+2 Copper Remover uses a patented two-step process that first oxidizes copper fouling and then captures it with a specialized binding agent to prevent redeposition. Its ammonia-free, barrel-safe formula is biodegradable, non-hazardous and odor-free, making it suitable for both light maintenance and deep cleaning sessions. This solvent can be safely left to soak in steel barrels for extended periods and includes a short-term rust-preventive film when a final patch is applied. Available in 4 oz and 16 oz formats.
