Denatured alcohol has methyl alcohol added, and denatured -does-
attack styrene, albiet very slowly. Most VCR front panels are/were
made of styrene. IPA wipes crayon off of it very well, denatured works
even better but you'll end up with bits of fluff from your rag welded
into the top layer of plastic.

Now things are made of different kinds of plastic, usually painted.
