Gary,
Well, it’s not straight forward but here it goes.
The following only applies to custom hand-lapped stainless steel barrels. I used the Wipe Out products but they do not work as quickly as some other products I am currently using. To get my bore clean “spotless” (As far as I know, I don’t own a borescope) I have found that Bore Tech Eliminator is a good solvent for both carbon and copper fouling. I use this solvent during each cleaning event. It works fast but must be used with jags and a rod that does not have a brass ferrule. If a conventional brass jag or brass ferrule rod is used you will experience false positive results on your patches. After several patches of Eliminator (a dozen or more), I will scrub the bore with JB compound using a nylon bore brush to rough out the fouling loosened up by Eliminator. At this point the bore is feeling smooth and consistent when pushing a tight patch though the bore. I then finish with Hoppes #9 cut with Kroil on a bronze brush to clean out all the JB and to scrub out the nooks and crannies. A tight fitting bore brush works well when the bore has a lubricating solvent in it like Hoppes #9. It is more difficult to push a bore brush down a bore saturated with Eliminator. The bore brushes clean up easily using Dawn dish soap and hot water.
There have been many bore cleaners that I have tried. Most of them have worked too slow or made too much mess for me to put up with. The products I use now work fairly fast, don’t stink too bad, and don’t make the skin on my fingers peal off.
