It depends a lot on what woods the strikers made of? Some woods sound better and play better, the dirtier they are. I like using a fine grit sandpaper on mine if I need to clean one. I don't care for a scratch pad, just because it glazes the tip too smooth, at least for a glass surface, a slate surface it works great. A couple of twist to clean it is fine, you don't need to sand it down just to make it play, if you do then junk that striker because it's not to good!
