So i finally bought some of this stuff and I was really impressed.  I cleaned my M44 with Hoppes #9 powder and copper solvent, as well as Ed's Red, a couple of times already and was convinced my bore was clean.  

Well after treating my barrel with this stuff, the foam turned blue after 30 minute wait, i kept gettting dirty patches. after 30mins of swabbing I finally get a clean patch.  Never knew I had this much residue in the barrel.  

makes me wonder about cleaning it electronically.
