FWIW; I don't wear my white tux or my kidskin gloves when shooting. When I was shooting indoors (a lot) there was no concern for "extra smoke" and the range had restrooms with soap and water. My range bag also contained rags/hand towels to wipe a gun with, if necessary. When I go up in the hills shooting I take water and paper towels to get excess GSR off my face and hands. I also clean my guns after a range session, that's part of being a responsible shooter . I have never had a "problem" with "dirty Unique" and I use Unique in my 357, 44 Special and 44 Mag, 45 Colt, 380, 9mm and 45 ACP and if I use light loads of Unique, they may be considered "dirty", but if they are it is of little/no concern to me. I also use "new and improved" powders but my Unique loads are consistent, good accurate loads...
