Cu+2 Copper, 4 oz

Prefer this over the ammonia based solvents! Works great and gets the same result as the smelly ammonia based copper solvents.

Bore Tech Cu+2 Copper, 4 oz seems to be a quality chemical for helping remove copper build up from rifle bores. I have used it in conjunction with other Bore Tech products and find it does a remarkable job of removing copper, as do the Carbon removal product and the all-around product for removing the carbon and both copper and carbon. Just follow the directions and repeat them as necessary and you will enjoy rifle bores that can be as accurate as possible because of removing built up fouling from the bores. I cleaned up the bore of a Winchester 67 22 that had sat neglected for almost twenty with nothing but a regular cleaning instead of a deep cleaning as provided by the Bore Tech products. Now there is hardly any fouling left in the barrel, and I am anxious to shoot the rifle again to see if the accuracy has indeed improved. A 90-year-old rifle could be a shooter as good as it was in 1934-1937, hopefully. This product should not be used for deep cleaning after every visit to the range, but only if accuracy begins to degrade after much shooting.

I had an old rifle that started keyholing and I was worried that it was toast. After only one thorough cleaning with this copper remover it was back in shape and working great! Can’t recommend it enough.

I have a barrel that is a copper magnet, and nothing I have tried seems to work effectively until now. Just tried this CU+2 in that same barrel and I was totally amazed at how easy and fast it was. I believe that if I had a tighter fitting nylon brush, that tiny bit of copper that is left would be gone for sure. This product is now front row on the cleaning shelf.

This product is the absolute best bore cleaner I have ever used. Not the cheapest but it’s worth every penny. Follow the instructions on the bottle to the you won’t be disappointed.

Way too expensive. Way effective, though. Switched to a nickel-plated jag and still saw a lot of blue on the patch with the first swipe. No ammonia odor, doesn’t stink up my cleaning room. Been going back and recleaning my cleaned firearms, discovering some of the other cleaners weren’t so effective.

I remember when my guns were always perfectly clean. Before I got a bore camera. The copper fouling that I never realized was hideous. This product is nice. But it ain't no JB compound. The JB gets the copper O-U-T. Just don't overuse the JB.

This stuff really works great.
