I am like you I wouldn't want to screw it up either.From my experience grafitti removers seem to be a lot stronger than alcahol when used on plastic items and surfaces.It's like it actually melts a layer of the plastic,at least the ones I have used.I have found that denatured alcahol does not react to plastic like grafitti removers do.I know a painter that uses a rubber seal product also called oil and grease remover on plastic and metal items and it seems to work on cleaning up dried compounds after buffing a paint job.And that stuff can be hard to remove.I hope you are able to get the stuff off without any damage.I will keep asking people that I know to see if someone can come up with a solution.
