As usual, I tried it when it first came out. Anything to lessen the workload.
Didn't like it one bit. Very slow and does require multi applications. Also, if you don't stand the rifle just so, solvent will ooze into the mag well as it turns to liquid. If you don't cant the rifle enough, foam will not got to the chamber area.
If you figure out the application technique, it does work...kind of.
I tried it on match barrels that don't foul much at all. Effective enough. But then anything will clean those barrels in a few patches.
On a heavy fouling factory barrel, forget it. Spray, wait, swab, spray some more, wait, etc. This could take several hours. Not for cleaning at the range for sure.
At the end of a few cycles, I just got some Barnes CR10 and ran a few wet patches. Wipeout did not clean out all the copper and the Barnes patches were still blue.
5 min. with the Barnes and all gone. If anyone wants a 2/3 can of this stuff, they can have it for free. Also, have Hoppes #9 copper remover, Sweets (slow but can work), Butches Boreshine (waste of money), and maybe any other cleaner that I have tried that failed to do what I want.
Only Barnes CR10 has been quick and effective enough for my use. However, for what they charge, I can get some GM top engine cleaner and a huge bottle of janitorial grade Ammonia. Solvent cost drops to 20% and it works as well or better.
The foam is a nice idea but the time it takes to wait for one barrel, I have cleaned several rifles my way.
