My brother was eating something very crumbly, I tried to clean as much as I could off the piano keys but some of the crumbs feel in between the keys. Is there anything that can be done about it?
, if you have the experience disassemble the piano, I have found for you this video. Here the cause of wedging the two keys between itself was a colored pencil rod
. You have to disassemble youself access to the keys and if they have a similar defect, first act to removing the keys. Second act its montage "native homely place"
You can also try to vacuuming. Good luck for You and your brother hellohttp://www.youtube.com/watch?v=UqgSK4TZ6W0
