My gun is brand spankin' new, I haven't put one round through it yet, but I had to take off price stickers from when I purchased it. I still can see where some adhesive is on there. What's the most effective way to get rid of stuff on the slide besides water and cloth? I have this stuff I used to use on my exhaust pipes on my old Mustang called Nev-R-Dull but I don't know if that's overkill. Halp?
