Please do not spray anything on the keys to clean them. Use weak liquid detergent and warm water.......dip a white cloth an wring it very tight so it just damp.........clean the white keys first.........then another cloth......dip in clear water and wring it tight and wipe them off.............then dry them with another white cloth. Now do the black keys careful not to touch the white keys or you can get a color transfer on the ivory keys. It is suggested that you use a machine in the room that collects dust to keep it out of the piano. Anyone who wants to play it should wash their hands first to keep the keys clean.
