stripping paint off of plastic trim parts

[mybuick]

ive seen that my interior parts are from a 1987 car and painted for the 84 car, cuz i scratched the paint off of the sail panels. how do i strip the rest of the paint so i can repaint them? these are palstic parts.

I've used soda on bumper fillers with good sucess. I don't know if it would take the grain off of interior parts though.

There's a stripper for Urethane but it will swell the plastic

Easy-Off oven cleaner will remove the paint but not harm the plastic.
