I applied with 100% Ethly Alcohol on a piece of face tisuue, rubbed on the finger prints, rinsed it with distilled water, repeated a couple of times. most of finger prints are gone, or get thinner.
However, I feel the sound is getting bit thinner also now comparing to the other side I don't clean. It could be just me. :-(
