You'll be lucky. Acetone dissolves acrylic well enough that a spill

Greenhouse friends of mine from the 1970s use acetone exclusively for
their orchid containers. All solvents which attack acrylic will damage
the surface and most work really well for glue. Acetone is thin, quick
drying, and has a very nice capillary action. shrug
