I've written on this and other forums about the cleaning and polishing qualities of Flitz. I used it on a Python Elite's matte stainless and now have a mirror finished bright stainless gun. Another effective compound for cleaning powder burns off the front of stainless cylinders is " Mother's Chrome and Mag Wheel Polish". Wipe it on, let dry, wipe off. No more messing with nylon brushes, etc. Hope this helps. -Asa
