Yes you can use it to clean it out get some pipe cleaners and run them in the holes after you have soaked them in Ed's for awhile. I store my Ed's Red in a glass canning jar with a metal lid even a old sauce jar will work.
Ed's Red will do but mineral spirits will do just as good with no mixing/storing hassles. You can get a quart of this stuff at the hardware store for about $8.
That and a cheapo nylon toothbrush will get that junk out of the barrel ports with minimal effort - 5 minutes max. , no need to poke around each individual port. Take care not to get the solvent on your finished wood pieces.
Joe, you really don't even need to soak the area. I just give the ports a pass or two with the mineral spirits on the brush then let that work while I bronze brush the inside of the bore also with mineral spirits. This stuff is not as volatile as acetone so it will stay on the surface for quite some time. Soft brush once more outside the ports and wipe down. That gets them clean enough for me but if your not satisifed at that point repeat once more.
One thing to remember about a solvent like this is that there won't be any protective oil on the metal surface when you are finished so you might want to wipe everything down with an oiled cloth before you put it away.
I use remington bore cleaner for my ports.Comes in a nice little bottle,tip fits the holes ,drop a bit in each port,then spread some in chamber.Position gun so it drains down while I get the Hoppes 9 out.put a patch on,run it down and back barrel.then use a swab down .Then I run a snake down.Then I spray rem oil in each port,and in chamber ,again position gun so oil can start running down barrel.Put first snake away.Get second snake out,run it down barrel.Then,one more time rem oil in ports,then Gunzilla around chamber,position gun so it runs down barrel again.Put second snake away,run third snake down barrel.Spray gun with rem oil,then rub down with rag.
I should remain silent... but. I bought my old Perazzi used. I cannot even begin to explain the amount of gunk I cleaned out of that gun, including a couple of porting holes that were caked shut with carbon. Call me what you want, but a tool that is kept up and well maintained always seems to last forever. Just seems to me its like buying a car and never changing the oil. Clean the gun, give it a swab of oil and shoot the heck outta it.
