ThorroClean Bore Cleaning System

use a carbon remover to remove carbon..what a silly idea.
gm tec( top engine cleaner) was one of the best, i still have some.
subaru makes some that works
mercury outboards have a cleaner that works and still available.( seafoam ?)

Mercury Power Tune..have not used it in a rifle barrel
 
Received the Thorro Clean today and tried it out. My first impression was the cleaning solution is simply Iosso paste in liquid suspension form. It cleans pretty much the same way as Iosso which is VERY good. I cleaned a 6BR Criterion barrel that had been previously cleaned with BoreTech C4 carbon remover/brass brush followed by BoreTech Copper CU+ copper remover and nylon brush which is my normal bore cleaning regime. The Thorro Clean did remove some additional copper and carbon, providing the type of cleaning I typically see when I use Iosso paste.

I might just have to try the thoroclean especially in factory rifles that foul the worst first. Then if it maintains my accuracy I will try it on my good barrels. Looks to be a good product.
 
A story my Dad told me, was that when Chevrolet came out with their 265 c.i. V-8 engine in 1955, they could not get the rings to seat, thus burning oil.
Chevrolet's answer was to gradually pour in a can of Bon-Amy down the carb. to seat the rings, and it worked. Anyone else remember this tale?

Cleaned one my rifles yesterday using Thorroclean for the first time. It does appear to be Iosso paste in a liquid suspension.

I still have a can of GM Bon Ami. I don't know if their intent was to use it to seat rings but I know it was tried more than once.

wouldn't it be easier to just use the Iosso paste (instead of the liquid form)?

.....wondering if there's any advantage to this new 'system' vs. Iosso paste.

It must be an optical illusion, but it appears that the twist rate is phenomenal.
It's optical confusion. It's a 1/10 twist through a 22" barrel and you're seeing all 6 lands. And I faced the barrel towards the window to get more light and the reflections of the tree limbs in the bore makes it look warped too.

Yes, that is the truth.
