Dick, I've had some success using household cleaners like water soluble "LimeAway" and concrete cleaners for mostly metal hardware. Keep in mind that once the state of cleanliness is obtained, item should be rinsed with hot water and blow dryed with compressed air, not a hair dryer. Electronics hardware should be removed or protected during this metal only process. They're all somewhat ACIDIC compounds, so try a small area, but above all USE SAFELY and AS DIRECTED. I've found a lot of normal old grime and goo can be removed with a whitewall cleaning compound called Westlys "Blech White" Hope this helps. marv :I just got an RCA model 1 tube radio that was stored in a very dirty location for about 20 years and it is filthy. I used my shop vac to get rid of most of the clumps of dust, but the chassi and the cabinet still have a lot of deep soil. I usually use soapy warm water to clean radios, but this one may need some more serious methods. Any good suggestions are appreciated. |
