Hi all, It's been a while since I last posted. After many years of cleaning my clocks by hand, albeit effectively, with a brass brush, I am considering investing in an ultrasonic cleaner. From the relatively basic research I have done so far, I understand that there are a great deal of different models and specifications, so could anyone suggest a model that is efficient and affordable (as I'm an amateur horologist, not a professional)? As an aside, do you regard ultrasonic cleaners as the best solution for clock cleaning, or are there even better options in your opinion? Regards.
