I didn’t mean flux.? I meant the green material that coats most of a PC board.? Some of it usually has to be removed to modify a board.

I presume you means the colored overcoating.? IF so its an epoxy material and very tough
so abrasion/scraping is the near only means as anything aggressive enough to soften it?
will likely damage other parts.

If your removing flux residue, Isopropanol-91% cheap and any pharmacy has it.
Do not use near fire or flame.
