Developed through years of advanced chemical research, the Cu+2 Copper Remover™ is the patented copper remover that surpasses the rigorous demands of today’s top shooters and cleans copper fouling faster than traditional petro-ammonia based solvents.




Cu+2 Copper Remover’s proprietary formulation and cleaning process is designed for one thing; continued, rapid and complete extraction of all copper fouling in your firearm’s bore. The key to the Cu+2 Copper Remover’s unparalleled copper removing capabilities is an industry unique two-step process.

In the first step, the Cu+2 Copper Remover rapidly oxidizes and breaks down copper fouling by reconfiguring its electronic state. Once the copper fouling is oxidized in step one, a specially enhanced binding agent within the Cu+2 Copper Remover’s formulation acts like a magnet capturing the copper and rendering it unable to redeposit in the firearms bore. This exclusive technology allows for the complete extraction of copper fouling at full strength without becoming saturated and losing effectiveness.

Our copper solvent is 100% ammonia-free and barrel safe. It will not etch or harm barrel steels and can be safely left to soak in the bore for an infinite period of time. In addition, the Cu+2 Copper Remover also contains a short-term rust preventative, which shields and conditions the firearm’s bore after cleaning. Just dampen your last patch with Cu+2 Copper Remover and your bore will be protected against rust and corrosion for up to 2 weeks.

Simply put, Bore Tech’s Cu+2 Copper Remover works faster and better without the fear of barrel damage and the dreadful ammonia smell. After years of trying, this is the copper remover you’ll be buying.

Impressive 5 of 5 stars

I’ve used a lot of different solvents and cleaners to clean the bore of copper. Most are pretty noxious. This stuff is pleasant to use and works better than anything I’ve used. I switched to this since I have young kids and can be interrupted during the cleaning process. Other products will damage your barrel if you leave it in too long. This will not. Great stuff.

Wow - Fantastic! 5 of 5 stars

Purchased this from a local gun shop, and wasn't sure I was making the right choice. You know, because I didn't have the inter-web telling me what to think and all. Shop owner said try it. It was cheaper then the latest youtube giz, so I did. Holy cow!!! This literally saved a Browning BAR Safari from the chopping block. Cleaned the barrel per instructions, and went from 4" groups to a 1" group at 100 yds. Thanks Bore Tech!!!
