Difficult! It actually was silkscreened ink many years ago, but it's a form of epoxy resin these days. There are solvents for epoxy resin, but they are rather nasty.

It's typically made out of the same material (epoxy) that holds the PCB laminate together. So anything you use to attack the silkscreen ink will attack the PCB itself. You can remove it mechanically (sand or grind it off).

Besides Leon's and Spehro's comments, If there is soldermask on the board, the silkscreen and the soldermask are similar epoxy materials and they are basically unseparable. What may attack or soften the silkscreen will likely do the very same to the soldermask.
