3M makes an adhesive remover that says:
"Dissolve overspray of many adhesives used in countertop lamination"
Granted, it doesn't specifically mention Contact Cement, so it might
be worth a phone call prior to purchase,

You can try also lighter fluid such as Ronsonol - the kind used in cigarette
lighters, not the kind used for charcoal.

It will dissolve many adhesives without damaging the paint or plastic. I
don't recall if I've ever tried it on Contact Cement but it is my go-to
adhesive remover for stickers, tape, tape residue, etc.
