I picked up one of those old PS/2 keyboards that IBM used to make. Remember the ones with the great clicky keys and removable keycaps? I bought it for a whopping $3 at a used computer store and its in pretty damn good shape. Considering it was sitting on a shelf among a pile of old keyboards, and its almost 10 years old, its wonderful. I'd like to clean it up so it looks almost new, but I don't want to risk damaging it because among some people, its a treasured antique. Can anybody suggest a good safe way to clean the keys and the cord? I'm concerned about harsh solvents that might remove the lettering, although they aren't the least bit faded so maybe that's not much of a problem. Heck, my 1 year old IBM keyboard shows more wear than this old one.
