IOSSO PRODUCTS - Iosso Bore Cleaner

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.
