Use it once a year. Spray in the barrel out side because it will come out the end of the barrel. I use short spurts of the Wipe-Out so it doesn't just fly thru the barrel. Put empty plastic bottle over the end of the barrel so if anything drips It catches while you wait for it to work. I leave it in the gun for an hour. Then follow the instructions to use patches to clean it out. After clean put some solvent like Shooters Choice on a patch and clean like normaly to get anything that might be left. This Wipe-Out takes out a lot of copper and such so next time you shoot you will have to shoot some fouling shots before the barrel is seasoned and ready to go. Great stuff.
