Clean it up? Yes but should be done wearing by now . The plastic rails"assembly" rails that is will stop wearing and if you wish to make them look nice take some sandpaper after them or just scrap any plastic edges flat with a pocket knife. I do with any pistol soften any sharp edges and did so with my kahrs but not really needed. Go over talk kahrtalk and intro your self and do some searchs before asking questions. Most results have been covered thru the years.
