I have no idea what chemicals the communists used for either a CLP or a bore cleaner or what, but I have one of those WW2 era dual-cavity oil bottles and want to fill it with Break Free CLP. It's probably a good idea to clean the inside out thoroughly and I have no idea what if anything could react and potentially ruin the CLP or do something to the gun once transferred from the can. So how does one thoroughly neutralize whatever was in there and or has been in there since? Somebody told me to either degrease the inside or boil the thing and pour out the water then let it dry, neither of these ideas sound efficient or particularly great to me. I suppose one cavity would be oil and the other would have been a bore cleaning solvent? Does anybody else actually use these or just keep them to look nice?
