Iosso10215 Bore Cleaner - 1.5 oz.

This is the last step in cleaning my barrel. It leaves a beautiful shinny surface when done. I shoot Fclass and this can be 75 rounds in one day, strings of 20 with sighters. After a day of shooting my barrels are pretty dirty. Iosso really helps bring my barrels back for the next match

Great

Efficiently removed the copper from my firearm barrels. I recommend this product.

I used it in a .308 that I had already cleaned. I followed the instructions. Quite a few patches came out absolutely charcoal black.I will be ordering a few more tubes to put away.

It's a nice thick white paste. I'm running copper jacketed ammo and it cleaned the bore to a mirror like out of the box shine. 100% residue removal as far as I can see. I ran it through and let the paste sit in the barrel for 10-15 mins, and then put rod through until it runs clear, which was just a couple times. Very easy. I don't use toxic, harsh chemicals, or petroleum ever on my hardware as some finishes and materials can be damaged and have a stank smell to boot. So it can be a challenge to find non toxic green options that are safe for the environment and all the different materials found on modern hardware. This is a superb option. Blows away thin spray or oily type clearners in my opinion. I won't buy anything else to use. I don't trust harsh chemicals on chrome lined barrels or other linings used. This is my only bore cleaner from now on. Highly recommend.

Works well, but you have to use the product and a heavy brass brush, etc many times for it to remove stains and heavy carbon. Like that it isn't a heavy solvent that can be harmful.

The media could not be loaded. I have expensive guns. Many of us do. I have used every known cleaner, including Bore Tech, Slip Carbon Killer, Lucas Oil, CLP, and many others. None of them removed the diamond hard carbon ring in the breech of my MasterPiece Arms Creedmoor. Until Iosso. I applied a small amount with a patch, and let it sit for 15 minutes. Then, I used a NYLON brush to work it in. Followed with many clean patches, which came out dark with carbon. I repeated the process , and used my bore scope to see how it was working. Before Iosso, this same area was black with stubborn carbon. Try this. Imagine the results if I’d used a brass brush! Next time!

This is excellent for removing hard bore carbon. Will also remove copper fouling. Mixed with Flitz liquid or Prolix it makes a great bore cleaner. It is an abrasive but non embedding. It is easier to clean out of the bore than JB bore paste
