CLENZTEC Copper Remover & Bore Cleaner | Gun Bore Cleaner Solvent and Copper Cleaner | Odorless & Ammonia Free Formulation

It looks that it is doing the job.

Needed this to clean and store guns after shooting. Worked as expected and was recommended to me by experienced shooter!

I used to clean a few of my rifles. I did this after thoroughly cleaning first with a carbon cleaner. To my amazement, cleaning with this afterwards produced even more residue on the cleaning patches. Not sure where it came from. However, I didn't notice the tell-tale color of copper residue. It could just be that there was no leftover copper residue in my rifle bores. Either way, it's difficult to give this item a complete rating as a result. I'll update the review after more usage, if the results change at all.I did like the fact that it's odorless - a nice change from most solvents. The sprayer worked well also.

Works great for the break in of my new rifle.

This is my first gun cleaner, so I have nothing to compare it to. I used it on something besides my gun to remove some residue and grease, and it worked great! I only have one small handgun to use this on, and as far as I can tell it's a great solution. I agree with others; no unpleasant odor.I think I may have found a keeper, until I get another gun or a buddy of mine persuades me to try something else. I really like this stuff!
