For most plastics, it might be better to have a soap-and-water lubricated
abrasive. That would get rid of the plastic particles so they don't smear,
though it would require MUCH more abrasive compound. With toothpaste, at
least in the context of soft molded plastics, it might do more to smudge and
discolor the plastic, as it is mixed with the surface.
I've used it for polishing metals quite successfully, though.
