Cleaning Hardened Ultracal Off of form?

Hello, I hope this isn't too rudimentary of a question, but I had quite a bit of plaster splash on my fibreglass form when I molded my piece on it, and I have no idea how to get it off :(

    Not sure if this is the best way, but it's what I would try.   I'd soak it in warm water with a bit of soap, then start chipping away at it with wooden tools that are softer than the fiberglass form so they don't scratch it.  I'd switch between that and using a stiff-bristled non-metal scrub brush.

    Could be better methods, that's just what I'd try!
