I have a Smith & Wesson 5906 that us obviously all stainless steel construction. The bead blasted finish has finally begun getting some shine spots and small scratches on its surface. I heard that steel wool can be used and it will clean up the finish and take the scratches out. Problem is I donr know which steel wool to use or the process. Do I need to oil the surface before I put the steel wool to it? What type of steel wool do I need? I dont want to replace scratches with more scratches. Dont want to polish it with just clean up the blasted finish Thanks for any help.
