Great for stubbornness carbon

Started using this periodic after a recommendation from another score. I was having issues getting burned in carbon out of my barrel. I have used JB for years and believe this works faster. It leaves a nice polished bore that seems to be easier to clean the next time around.

Would you recommend this? Yes, I would recommend to a friend

My go to bore cleaner

I rely on Iosso Bore Cleaner to clean my pistol bores. I first clean out bore with a patch soaked with M Pro 7 cleaner, then apply Iosso to one of their nylon brushes and run back and forth through the bore until clean. I clean up excess with M Pro 7 cleaner and patches, and after run a patch slightly moistened with BreakFree CLP through the bore. Iosso certainly makes short work of FMJ copper fouling…noxious solvents are now things of the past.

One of the better abrasive cleaners

This stuff is calcined alumina oxide which is a 9 on the Mohs scale. Interesting stuff sometimes referred to as tubular aluminum oxide. None of the solvent based bore cleaners work. Get a bore scope and see for yourself. The most expensive rifle barrels are all hand lapped and polished. So why not maintain them as they were manufactured. You can feel the difference. Wrap a patch around a brush and work it. The first one you might need to pull to start. Go ten or twenty strokes. The second one will move freely. You won't need a third.

IOSSO wow!

I have been cleaning guns for 40 years. Their are several products that remove copper and do a good job. To remove carbon is much harder to remove I have tried several products and none of them work very good and some of them not at all. IOSSO says it remove carbon burn.A better term is carbon Glass. This product is unbelievable. I have a bore scope but if you do not have a bore scope wait until you see the pataches That come out of your clean gun.

Best Product Out There

A bore scope is the only way to tell if you bore is REALLY clean. None of the wet chemical solvents I have used actually worked like the labels said they would no matter how many patches I used, but, THIS STUFF WORKS! Run a few wet patches through to remove the loose stuff, then use the paste with tight fitting patches. Two to four will usually do it if the barrel is smooth and not too fouled, clean up with wet and then dry patches. On heavily fouled and/or rough bores, letting the bore sit with a coating of Rem oil overnight before using the Iosso will help, but don't expect miracles. Cleaning can still take some time with badly fouled bores, but this stuff works better and faster than ANY liquid chemical carbon and copper bore cleaner out there and with fewer passes with a cleaning rod.

It's OK

Meh. It works, but not miracles or anything. I'll try another brand next time.
