BORE CLEANER Reviews & Ratings

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.

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.

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.

Best there is, hands down. Thick paste sticks to patch and cuts carbon like nothing else. You only think your rifle is clean until run a patch of Iosso down the bore and see a black patch come out. Ive been using it for over 25 years and have found nothing better. Hard to find locally in stores, so Brownells is my go to for cleaning supplies. System I use is: Dewey rod w/ bronze bore brush wet with Hoppes #9, 10-20 strokes, then run patches til dry. Wet barrel very well w/ Sweets 7.62; let sit 20 min. Run patches to push out the blue dissolved copper til dry. Then use small amount of Iosso paste bore cleaner covering your patch, pushing patches through til clean. Repeat entire process as necessary to get clean patches and even again 2 days later if your done with the rifle for the season. Then run a patch with Hoppes light oil for storage. Simple.

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.

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.

I have used all kinds of products from a-z & this by far is the best product out there. The one thing I would highly recommend is that you use this bore paste with the IOSSO brushes & triple action oil solution. It is all made to work hand in hand for the best cleaning possible.

This is an outstanding product. I cleaned my .222 Rem which hadn't had such an effective cleaner applied to it. After about an 90mins of non-stop cleaning it came up mirror finish clean.

I USE THIS TO CLEAN ALL MY CUSTOMERS AND MY BORES. CLEANS OUT THE MOLY AND EVERYTHING ELSE. CAN'T GET ANY MORE COPPER OUT EVEN WITH MY OUTERS FOUL-OUT.

When you got to get it clean, removes ALL the copper from your barrel---THIS IS IT!!! Wipe out your barrel with solvent--look in the muzzle with a LED flash light--look at the copper. I use it on patches, 8-10 times back and forth, three patches and it is clean. It also polishes too, and it will not reomve metal or harm your barrel. Start cleaning with this every 10-20 shots and your rifle will start to come clean easy,the more your use it, the faster the job gets done and copper free too. I got great groups from a dead clean barrel once the barrel was cleaned a few times-(no more foulers)-clean up with solvent, dry and shoot.
