A couple of years ago I worked on a Georgian globe the surface was
heavily soiled mainly with nicotine and fly spots. The varnish
underneath was reasonably sound so a method was found to clean it
without removing the varnish. A number of different methods were
tried and the one which gave fab results was: on a small area say
3cm X 3 a square of spider tissue was place and then a film some 3mm
thick of 5% methyl cellulose brushed over, depending on the level of
soiling this was left for a minute to as long as five minutes. The
tissue was removed and the softened grime swapped off with saliva
dampened swabs. Good luck,
