[QUOTE="Hugnot, post: 2302524, member: 115658"] JB paste uses garnet (mineral) as the abrasive to clean up bad bore stuff, like mechanical action. If interested the Material Safety Data Sheet: [URL unfurl="true"]https://www.sinclairintl.com/userdocs/MSDS/749-102-003_J-B%20(R)%20NON-EMBEDDING%20BORE%20CLEANING%20COMPOUND,%202%20OZ.%20-%20083_default.pdf[/URL] My thinking is the black stuff in dirty bores is a mixture of crud containing primer residue, powder residue, bullet jacket residue, & carbon. Various bore cleaners break up the black stuff including dissolving copper fouling. I use foam bore cleaners, usually overnight in stainless barrels. After pushing out corrupted blue/black slime with a patch, I use a nylon brush dipped in 5W-20 synthetic motor oil & the surfactant oil sucks up the remaining corrupted blue/black stuff. J-B is used when things don't feel good. No burning candles in area. [/QUOTE]
