isopropyl alcohol is my solvent of choice these days: I have never found
a plastic that it damages and it's adequate as a solvent (not as good as
carbon tet, but it does take off grease).

Many years ago, I used isopropyl alcohol to clean a plastic hairbrush
and put it down on the counter. I returned later, picked up the handle,
and the rest of the brush stayed, in little pieces, on the counter.
