    Stuff in the valve caps show you that the high spots ARE wearing off your valves - suggests you may need to clean AND lubricate more often.

    Al Cass's is petroleum based and evaporates rather quickly - is is not synthetic or Silicone based.

    I've had to use a thread gauge as a scraper on some nasty pre-owned instruments. At other times I've used straight pins in the threads. I do know a euphonium player that keeps die cut chemical filters in the bottom of his valves and changes them with every bath. Seemingly works for him, but I haven't the right size die cutter or the right size thread die. I do know you can purchase chemical filter paper in rolls. At least he didn't have to wear black trousers to hide the oil drips.
