answer:I think you mean you’re trying to get the outer frame of your LCD Monitor – the plastic – clean. The LCD screen cleaner is meant for screens, and so will probably not clean appropriately and may leave residue. Just take a slightly damp rag, and run it along on the surfaces you need to. I’ve never had a monitor that needed more than that, what on earth have you been doing to it? ;) For future references, shiny, slick surfaces appear to be more dirty than matte surfaces as a rule. If it bugs you in the future consider buying one with a matte finish next time.
