I've been using Wipe-Out for awhile now, the range I call my "home away from home" has used it to clean awful fouling out of dozens of customers' guns. I've never seen anything like it, they haven't either. I got the bore nice and clean and it shoots well clean, only needs one fouling shot, just like Ol' Ugly.
It's a foaming cleaner, for normal copper fouling just fill the bore with it and let it sit overnight. Run 2-3 patches thru and you're done.
I always repeat the process once but the second time yields very little copper if any. For heavy fouling I brush it a bit with a nylon brush before running patches thru it. After cleaning I protect the bore with Break-Free.
