Last week I shot my 20 Gauge fusil. Cleaned thoroughly, using a mix of Murphy soap, window cleaner, peroxide, and alcohol (70%). This mix new to me, but worked amazingly well. Then swabbed with alcohol, dry patched, and put down some RIG. About four days later I ran a patch down, RUST!!. Operating on the Clean--Dry--Lube principle, I guess I must have failed on the "dry" portion, and lubed a damp bore. One fellow suggested that the use of 70% alcohol is wrong, in that it's so heavy on water the chance of rust is enhanced. No hot water involved I clean at the range, cold water. Id appreciate suggestions, advice. Also what do you-all prefer for bore protection once clean and dry has been achieved? Thanks, Ron in Fla
