@roger,
In my memory Sharpie (made with organic solvent or at least used to be) combines with at least some plastic, or infiltrates it, whatever.
Glass - I'm an old lab tech who labelled test tubes with sharpies. You can get it the ink off relatively easily with a scrub brush, etc.
I'm also a painter, and still have a gallon of turps (better product but works the same) around the house if I need it.
So what alcohol?
I certainly hope not a good wine or scotch.
