Silkscreen, Removing Ink from PCB?

[Newyankee]

Is it possible to remove printed silkscreen from the pcb without abrasion? Is there a chemical that can dissolve it? This would be removing a letter or two, maybe a polarity symbol or marking. This would NOT be to remove entire fields.

I don't know of a material that will only remove the silkscreen. The attached MSDS is for a solder mask remover that will also remove the silkscreen.
