The mechanical part: action mechanism, keys and pedals
A piano’s internal action mechanism is crucial for its sound production and character. Little felted hammers, hinging in nifty little bearings, have to find their way to the strings flawlessly, thousands of times. Between hammers and keyboard (keys) exists a complex, purely mechanical transfer system for each key, which, depending on the frequency with which it is used, is subject to a certain amount of wear.
In case of less serious issues, we recommend that you consult your tuner, who can usually mend the problem. When in doubt, don't hesitate to contact your piano tuner! Moreover, the tuner is supported by the company's technical service. The only mechanical parts you can maintain yourself are the keyboard and pedals. The keyboard can be cleaned by wiping it with a damp cloth and rubbing it dry with a soft dry cloth. Please don't use ethanol or other caustic cleaning products! The pedals can be polished with copper cleaner according to the instructions on the bottle. Make sure, however, that the copper cleaner doesn't come into contact with the case surrounding the pedals, as this may leave white marks.
