I was having to brush barrels repeatedly with standard commercial bore cleaners. The chamber would not come clean with the plastic fouling without long repeated effort. The SC Choke cleaner and the Ed's Red (with acetone) solved this problem. One good soak. Wait a minute - brush and clean out with patches. You can see pieces of the plastic coming right out. Most bore cleaners have ammonia to work on the copper fouling which isn't an issue with shotguns. I might go through a case of shells each weekend as does my wife so the plastic will build up if not totally removed. I work in my shed and have barrels in a padded vise so it goes pretty quick. I don't notice any issue with the acetone other than proper storage. Can't store it in plastic containers at least not high density poly. It might not be for everyone but it works well for me.

Also, use the brushes like you would use a jag. Solid J. Dewey rods work great also.
