I had read about that. I’d prefer to not have to reblue.If you're not concerned about preserving the finish, I recommend Evapo-Rust. It's generally not necessary to leave the item in the solution overnight, like the manufacturer recommends. I generally leave parts in there for 10-15 minutes at a time.
Pee on it and leave it outside.I am going to be removing rust from an old Marlin .22 and would like to know what the consensus is on best methods.
