Cleaning up after using corrosive ammo

[Lancebear]

Hoppe's No 9 is no good alone. They changed their formula years ago. Same time when corrosive primers disappeared in the USA.

Thanks Steve, seems like they have changed their copper solvent formula recently. Looks thinner and seems to be a bit more aggressive? Patches are coming out blue sometimes. Don't remember that, remember green. Could just be me, haven't used it in a great while, just regular number nine, brand new bottle with safety cap.
