One other point I thought I'd mention in regards to cleaning the plate. It seems that the longer the fine dust layer stays on the plate, the more it bonds to it. So when attempting to clean the plate with a liquid cleaner be careful. You can get the struts and large, open areas clean but the marginally accessible areas (tuning pin field, under rear duplex) require a lot more attention. So be mindful of the overall patina of the plate. it is better to have the plate uniformly dingy than two-tone. A dry or lightly damp rag will remove dust without removing that 'protective film'. -- Regards, Jon Page
