How do I get plasti dip off of plastic chrome?

So I bought my car from these people and they did a terrible plasti dip paint job, so I've been using lacquer thinner on the whole body and then using a buffer to shine it up and it's been coming out phenomenal, but now I want to restore the grille back to chrome but its make of plastic, so I dont wanna use lacquer thinner on it and take the plasti dip off but have it ruin the chrome as well, and it wont just peel off, is there any other way to get the plasti dip off without ruining the chrome?
