This is pretty common if you have a lot of rosin on your bow, and/or play with your bow on the loose side. It really has no effect on your bow as long as you clean it off within a few days (with any cloth is fine). If you find yourself doing this often, you probably have too much rosin on your bow. This is more of an issue regarding playing the violin (not ideal to have too much rosin).
