Remoil will be fine, I have some too, however it will have a limited application for cleaning the barrel and cylinder. If you are wary of hoppes, something like CLP on a bore brush through the barrel followed by a piece of cloth or swab should do the trick. If the firearm is relatively clean, wiping down with remoil is probably all you need to do. Sometimes I'll coat and buff the exterior in johnsons paste wax, which seems to ease the removal of carbon and powder marks when wiping it down after a range session. If you do clean the barrel and cylinder with oil, make sure to get it all out and avoid an unintended combustion event when firing. Even for a nickel finish some hoppes on a bore brush in the barrel and cylinder would probably be fine if you don't give it a chance to corrode the nickel exterior. If you carry the piece, expect some mild finish wear from contact with the holster over time.
