I used it once. It seems to clean real well but can be very messy. Hard to get the right amount without it becoming a foaming mess. DO NOT do this on the wife's kitchen table! Not sure it is what I would use all the time. Maybe if the rifle needs to be really cleaned from fouling that will not come out with standard cleaning fluids. I am a suckerfor all the "new stuff", I tend to buy more than I need and have stuff I have not even tried to use yet.
