I should probably wipe it down a little more regularly, but I do it now every month or so. My inspiration for raw steel Treks is the cultural sensation Ultraromance, which is to say that I'm not concerned about maintaining a conventional aesthetic i.e. clean and finished. The linseed oil keeps the rust from getting dangerous, and it does well in the rain. Chain slaps are super loud, though, so I'm going to have to wrap up the chainstay.
