Excellent Copper Remover

By Dwaine V. on Feb 03, 2023
First time trying this product. Have to say, it does an excellent job without a lot of effort. Not being ammonia-based, it is odor free, which is a bonus.

The Copper remover when used in conjunction with a nylon bore brush does an excellent job of removing copper from my barrels. I use it on all my rifles. The fact that it is not ammonia based make this my copper remover of choice.

Thoroughly cleans both carbon and copper.

This will clean your barrel very well without a lot of effort. I would not recommend getting it on your wood stocks.

Let chemicals do the work

If there is a better copper remover, I don't know of it. No bad oder, safe on wood and polymers. CU2 also removes carbon so this works on both. Let it sit all night is ok. If been doing this for 40 years. I've used a lot of bore cleaners I believe this one is the best.

Bore Tech Copper Remover is Magic

This and carbon remover are a great recipe!

I really like this copper remover. You do need to use Bore tech prof positive nylon brushes so you don't get false readings.

Works great just as advertised! Use it in conjunction with Bore Tech Carbon remover for a really clean barrel.

It works & its easy on the barrel

I've been using both Eliminator and the Copper remover for going on 6 months now. I've used virtually every other product out there and these 2 in combination are the best on the market that I can tell. I strongly recommend the Copper Remover, especially in combination with Eliminator.
