I have been testing WipeOut extensively for several months now.
Good copper remover, albeit slow. Factory barrels that foul badly need multiple treatments of severa hours to be effective. Custom barrels clean up much quicker. (Nothing new there, eh?!)
Not real effective for powder fouling. Use a general solvent for that.
WipeOut is convenient and odour free so I will continue to use it, however, it is more expeditious to clean the copper with Sweet's or CR-10 if you need the rifle ready the next day.
I recommend WipeOut to friends who are not real skilled at cleaning arms. I'd rather see their rifle soaking with the foam than have them running cheap rods and brushes in and out of the bore trying to scrub out the copper fouling.
A nice product, but not the pot of gold at the end of the range day!
