I have several of these C-Elements with a film over the coolant side. These are the plastic lenses that fit on the front of the coolant chambers on the Philips CRTs. I have tried every type of cleaner I can think of to remove the film that forms on these in many cases. Since they are plastic we don't dare use anything abrasive. Replacement costs are rather expensive on these parts. Have any of you had any luck cleaning these? Dave Huston Huston TV & Electronics 2846 Marion-Cardington Rd.E.
