I bought a can of this stuff a few months ago and finally got around to trying it this past weekend. Their promos recommend using it on a barrel that you think is already clean to prove how effective it is at removing what you missed. So, I tried it on my Shilen 223 barrel. After the recommended one hour soak, I pushed a dry patch through the bore and it came out clean, indicating that either I have been doing a good job cleaning this barrel or that the stuff just doesn't work that well.

Next, I used it on my Colt AR-15 barrel which I had shot the day before. This barrel is always nasty and takes forever to get clean after a trip to the range. I have never used any copper remover in this barrel and it has about 1500 rounds through it. After the recommended one hour soak, I was astonished at how much bright blue liquid came out of the barrel and how filthy black the patch was. To test how well it worked, I followed up with some Hoppes using six cycles of wet brushing followed by a dry patch. By the sixth cycle, the patch came out very faint gray.

Wipe Out has a very faint ammonia odor and if you asked me to describe it, I would say it most reminds me of glass cleaner with ammonia. Essentially, a strong cleaning solution with a little ammonia in it.

I'll use it a few more times on my bolt guns before passing final judgement. However, based on the first experience, I think it's going to improve my cleaning regimen.
