Richard: I'd take care with such products. Most stain cleaners are acid and can damage the plastic. You should try the product on a hidden area of a single key before using it widely. But... per your description I suspect the keys have suffered from a natural degeneration of the polymer. Several old synths have the keys slightly yellow because of this. Good quality (read expensive) synths and electric pianos often use plastic with a special component to avoid it. Also the action of sun results in the same yellow aspect. Sometimes the shape don't get distorted but the color changes. My Juno 106 has the keys in good shape and color after almost 20 years but the panel buttos are all yellow because of excessive exposition to sun. By the previous owner, of course. ;^) In both cases the result cannot be reverted. There's no way to get snow white keys back because it's not dirty, it's a change in the material itself. Arnaldo.
