Be careful doing knobs with the ultra sonic cleaner. DO NOT use the heat function or anything like Simple Green in with the water or you may discolor or deform the knobs. A little diluted dishwater soap will do the job just fine or even just the water itself.
That said, those cheap ultra sonic cleaners that Harbor Freight has work very well for tuning caps, knobs, etc. Think I paid $30 for mine and it has more than paid for itself over the years.
