Question - I have been cleaning barrels with both Hoppes Bore shine and also bore foam. I have left them soak for a few hours and then swabbed them out. Patches come out blue. They look clean to me, but then I run another patch down and it still comes out a little blue. I am using brass Jags, and brass is an alloy of mostly copper with a little bit of Zinc. Is the copper in the jag reacting with the cleaner giving me a blue patch?
Wipeout seems to do the job for me. I've never tried KG12.
