Chemical for removing silk screen and solder mask layer?

Hi, I would like to completely remove the silk screen and solder mask layer on some FR4 boards and leave the boards (fr4) and the copper traces (as well as the lead solder) without damaging them.
Is there any such chemical?
I guess there has to be something that attacks plastics but not metals and fiberglass.
 

Hi,

there are various solder mask types. Film, 2K, oxidizing...
Thus you need individual techniques.

--> Ask the PCB manufacturer.

Try Tri or Tetra.
