I have become a big fan of Kroil...
I use it on revolver cyl. and frames... soak the stuck on carbon stuff...gun pooo... and let it sit... then wipe it off... no rubbing to speak of and no brushes etc. to clean the flutes on a revolver cyl or the frame... stainless cyl. faces come clean with only a brief soaking...
I use it on bores that are heavily leaded... soak it repeatedly and let it sit... sometimes for a few hours and sometimes for days and then scrub with a brush... amazing how much easier it is to "get the lead out"
For heavily fouled barrels with alot of copper in it... same treatment...soak the kroil...
It is also handy stuff for rusted on stuff like bolts and screws....
The guy who told me to buy it said... Kroil creeps.... beneath almost anything... like copper, lead powder fouling... etc...
Don't know if it really works that way but it seems to ...
