Cleaning? hopefully not with fluid substances ... Pencil is fine, or graphite powder meant for locks. Also tallow, or non perfumed baby powder will do the job, maybe Good Ole Rick can bring you some from Texas on a sunny day? - Nout
PS Tom, something went wrong, can you remove the post above this one some day, thnx.
Spills of graphite powder can foul up the white leather on the flappers easily, and attach itself on too rough paint surfaces, hard to cleanup maybe. To be safe i would disassemble the whole keyboard and remove the nasty rocker from its slot. Keep track which rocker fits which slot by numbering them; with hand made instruments sometimes the width varies a little. - Nout
Ok. Couldn't get the powder to to the area but was able to get Howard's wood wax in the crevice using a metal ribbon ruler. Worked perfectly! Thanks for the suggestions!
