So having picked up a couple of "vintage" keyboards as of late, I was wondering if anybody could provide tips on how to take various substances off of em. I know that for a general cleaning it has been suggested diluted Bleach or OxyClean, any other suggestions?
Also, Is there anything to be done about removing the yellowing effect from old plastics? I know it's a chemical reaction, but past stripping off the top layer of the plastic, i have no knowledge of how you'd rectify the situation?
Tips? Tricks?
