Yeah, and I'm starting to get indigestion.
More than likely it was a mix of carbon and melted plastic wad. The acetone attacked the plastic, but does not do much for the carbon. Mineral spirits hits carbon fairly well though .
I was using it on the gas rings and along the magazine tube area that gets real nasty. But like a previous post pointed out, that may just be powder fouling??? Not Carbon fouling??? If it's powder fouling then where does this carbon come from. I thought it was from the powder burning?
If you want a good carbon cleaner, see if anybody out there has some of the older GM Goodwrench top engine cleaner in the silver & black can, part #1050002. That stuff really works on carbon. A lot of the old timers in BR shooting mixed that stuff with their regular bore cleaners that they used. I mixed it with Butch's Bore Shine and it did better than just the straight bore cleaner. I hear the similar stuff that you can buy from a Subaru dealer work well.
Yeah, I've heard good things about that stuff but finding it has been the hard part.
There has been times where someone has walked into the parts dept of a GM dealer and asked if they had any of the old stuff and once in a while somebody has scored some tucked away on a shelf collecting dust.
Ace Hardware, Lowes, Home Depot. Look in the paint section.
This is about carbon cleaner isn't it?? Or is it about shotguns? Now I'm confused.
