Ballistol was made to clean out corrosive residue. It is water based. Though I still use water. I spray cheap ammonia down the chamber, and bore. Let it soak till I get home. I then spray some more, and wait a few minutes. I pour hot, as in hot from the tap hot water to flush it out with. Rinse one more time. I then run a few dry patches. Then clean like normal. The ammonia helps to get the copper fouling out as well. Lots of blue liquid, will come out of the barrel.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
