I just cleaned the riveted-on dial on the Model 43 radio I am restoring. I used Windex, and a lot of the grunge came off. However, there are still "arcs" of black streaking where, I suppose, the dial rubbed against something. I was wondering if there is something that will clean that, without damaging the ink in the dial which is in perfect condition. Also, is there a product that will restore some luster to the plastic? It was warped on one end, and wouldn't travel down into the chassis slot--I used a hairdryer and finger pressure which fixed that nicely.
