I manage our club's military rifle and pistol match program, in which a lot of corrosive ammo gets fired. The best and most common solvent used for eliminating the corrosive firing residue is Windex. Not the cheapo blue stuff from Dollar General either.....real, live, blue, name-brand, Windex.
Our bore cleaning procedure is to squirt Windex in the chamber until it runs out the bore, then start running Windex soaked patches through the bore on a jag from the chamber end until they come out white - usually about five or six patches. Then dry patch it and clean the bore as normal. Flushing, scrubbing, and wiping other parts with Windex will also neutralize the corrosive elements there too. This is so common it is even written into our Club's Military Match Manual. I've done a ton of it. I like the convenience of having a squirt bottle of it in my range box so I can get the process started before I even leave the range.
Then clean the rifle as normal after the Windex treatment. Best wishes.
