Bullet Central teamed up with Iosso Products to develop a breakthrough bore-cleaning product. ThorroClean Bore Cleaning System provides a quick and thorough cleaning of the rifle bore. It completely removes copper and carbon fouling quickly, without any wait time and difficult cleanup. The active ingredients are gentle on a barrel and should be used in the same cycle as you would your regular cleaning regimen.

You can develop your own cleaning method but we know that the following works. You should have a well designed and made bore guide. It also helps the cleaning process if you have a solvent port as it is easier to administer ThorroClean.

Step 1 Push a wet tight patch through your bore to push the excess of carbon lying in the barrel. This gets rid of the loose fouling in the barrel.

Step 2 Liberally introduce some ThorroClean (about a teaspoon full) to a good bore brush. We prefer using the Iosso nylon bore brush. Stroke the barrel forward out through the crown and back about 10 to 15 times. Check to see if you have enough ThoroClean on your brush.

Step 3 Push a dry patch through the barrel and follow that up with patches liberally doused in ThorroFlush. You should be able to clean all the ThorroClean out of the barrel with 2 or 3 patches. Make sure that you do not have excess ThorroClean in your solvent port Check it out with your borescope.

The results will be astonishing. Your bore will be free of copper and carbon fouling and literally leave your barrel looking like bright clean steel, you can see just how clean it is with a Hawkeye Borescope.

    I’m very impressed with this cleaning combo. I followed the instructions exactly, including the Iosso brush and found my barrel very clean following the very quick routine prescribed. Much less time than previously taken using various cleaning agents and regimens, and with superior results. Very little product is used, so the amount included in the package should go a long way. No need to inquire about giant size bottles! Thank you Bullet Central and Iosso.

    Best bore cleaner ever! I used a tight brass brush and 20 strokes during my last benchrest match. After the weekend I used a bore scope and found the lands and grooves just as shiny as the outside, no copper and tiny bit of carbon. It’s my cleaner from now on, much simpler and no waiting time, scrub flush and shoot.

    Love this stuff, so easy and fast to use and does a great job. I use it between matches to get out light fouling and when I’m using dirty burning powders or when shooting in summer time high temps when fouling seems to increase. Gives me confidence that my bore is in good shape!

    Makes cleaning quick and easy. No nasty solvent odor and no need to wash and scrub your hands right after cleaning. I confirmed cleanliness with a bore scope. Best cleaner I’ve used in my 30 years of cleaning firearms.
