My experience with WO/PO products was basically a waste of my time and money. I did an experiment a couple years ago with patch out product against my normal regimen to clean my barrels. I used the wipe out product as advertised, with absolutely NO luck! I even tried letting sit over nite and even for 48 hours with no luck, patches still came out blue.

So I tried my normal routine with Shooters choice/Kroil mix, 30 to 60 ratio. Patch out till no color or just a hint of gray. Then I use CR10. 10 wet patches, reapply and 10 more patches, let sit for 10 minutes, then apply CR10 to a nylon brush, and scrub barrel 10 strokes, reapply CR10 to nylon brush and scrub 10 more strokes. 1 wet patch CR10 and patch til no color and dry. For my test I run a patch of alcohol down the barrel to get residue cleaned from my barrel. Then I did the patch out thru barrel, and NO color!
As a side note, now I use colloidal graphite after cleaning to treat barrel till next shooting session, In my opinion, this makes next cleaning a heck of a lot easier after a hot day of shooting in the Rat Patch!
