Let's face it, sometimes your guns get rusty despite your best efforts to give them the care they deserve. When that happens, you can show them some love by cleaning of the rust with Blue Wonder Gun Cleaner!
I learned about Blue Wonder gun cleaner June 2011 at NRA Basic Rifle at the Durham Rifle and Pistol Club. The instructor's name was William Guyer. Guyer explained a lot of gun lubes and gun cleaners are toxic and cause cancer. Guyer gave the class a list of his personal favorite gun cleaners that are less toxic and bio friendly. One was Blue Wonder. I finally bought some this year to clean up two older shotguns, including a 1936 Winchester Model 12 shotgun I am rebuilding at the Gunsmithing program at Montgomery Community College in Troy, NC. I have found Blue Wonder more pleasant than my standard Hoppes #9. Blue Wonder take rust out better than Hoppes #9 and does not have a "causes cancer in the state of California" warning label on it. Guyer told us to look for that label when choosing a gun cleaning or lubricant product. It also smells better than other bore solvents and it removes plastic shotgun was well.
I used half of bottle blacken my barrel over and over never got black dark
