Nord Lead 3 key grease

Hello All,

I am trying to get a Nord Lead 3 back into shape. It has been kept covered in a clean environment, but it is starting to show signs of age.

After a cleaning, most of the knobs are working properly, however the keys have also gotten quite sticky. The source of sticking seems to be the area underneath where they are braced by a knob that prevents them from pulling up off the keybed when you press it. Is anyone familiar with a grease that could be used to get them lubricates again?

For that matter, does anyone happen to know where I might find a replacement keybed altogether? I’d like to keep this keyboard going as long as possible.

Don’t the Nords use Fatar keybeds?
