Use 70% isopropyl alcohol, from any drug store, to clean winding and the 
part of the contact wheel that rides on the winding.  Your sighted 
helper should see a  load of black  junk transfer to your cleaning 
cloth.   Keep at it, changing  the area of the cloth as needed until it 
doesn't pick up any more blak.  At this point the winding itself should 
be bright and shiny.


If the design is similar to the Palstar I have, the contact wheel rides 
back and forth along   a shaft.   This shaft is coated with conductive 
grease.   If you clean  the existing grease off the shaft, you will have 
to recoat with  some sort of conductive grease.   Sorry I don't know 
what to use here.

Don't get any of the existing grease(or new grease)  on the winding, or 
the contact part of the wheel.
