Try Amyl Acetate (nail varnish remover as a substitute). Add it with a
dropper and use absorbent cloths to soak up as much as possible.
If that doesn't completely work then take a look at
www.DrClean.co.uk/surgery_stains/stains_techniques2.asp which shows a biro
stain being removed and the same technique should work.
Hope this helps
