Anyone got any tips for cleaning a sheet of Monogram decals from an early eighties stock car kit ? I bought the kit on ebay recently and it is complete but hasn't been stored well over the last 20 years or so - whilst this hasn't been a problem for the plastic parts the box and decal sheet show signs of damp/dirt/mould - I would guess it's been stored in a basement or something.
The decal sheet itself seems to be more dirty than anything else and I wondered if it might clean up prior to application with some zippo lighter fuel or something (I used to use this in a photographic business for cleaning dirt and gum off the surface of photographic prints without harm).
Any opinions/experience here much appreciated.
