What material is this? Metal? Plastic? I think they usually say to use acetone for cleanup, but I'd be worried about that on the paint and wouldn't use it on plastic. Some paint thinner might be better, I think most paints will tolerate that for some period of time, but I wouldn't leave it on too long. And try whatever you choose on a hidden spot first. Mineral spirits or gasoline would be other choices.
When i worked in the cabinet shops we used naphtha , sometimes with a dash of lacquer thinner to help soften the stuff . Old contact cement is going to be harder to remove ... you might try WD40 , it's basically a solvent .
"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.
