Several moths ago, I was given a sample of IOSSO Gun Oil with a nylon brush. I also purchased the IOSSO paste. After only a few minutes of cleaning I started getting clean patches. I was also using a double thick patch so that I could pick up as much fowling as possible. This seemed too good to be true. The next day I went to my Copper Dissolving chemicals and my United Kingdom style oil. There was NO Bluing on my copper patches and there was the faintest hint of grey on my oil patches after a 12 hour soak. IOSSO combined with a properly broken in barrel is the only way to clean for me. Thanks..keep up the good work
