ok, i have heard and read a lot about how well this stuff is supposed to work for removing copper from bores. so i went out and bought a bottle. i have tried it on several guns, following the directions. but every time, after i am done, i return to the old standby (hoppes no 9 bench rest (copper solvent) and get more cooper out of the bores after leaving them soak over night. i have tried multiple applications of the sweets, but i still end up with copper left behind. i let it soak for as long as the directions say. what happens if i let it sit for an hour, or two? am i missing something? is there a trick i need to know that help this stuff do its job? and, yes, i scrub it with a brush several times while using it. and i have tried just letting it soak. thanks, moooose
