I don't think you want to have *anything* on the gold-plated contact
surfaces. The contact pressure is very low, and the keyboard encoder
chip already does ample debouncing.

But, it is helpful to have lubrication on the plastic slides that the
move up/down as you press the keys. There was lubrication from the
factory (maybe just the plasticizer that comes in any recently molded
plastic), but it dries up over time and the keys can bind if you push
them off-center.
