[GreenKeys] Model 28 Keyboard arrangement

[John, W9DDD]

I've done 2 keyboards to removed the nasty white stuff.  One was a mark 
II and other a mark III.  Not much difference in the process.  I removed 
the hood and the top plate.  I then proceeded to go one by one removing 
a key cleaning it with Scotchbrite (a Brillo pad like product made of 
plastic) and Pledge.

Pulling a keytop off is aided by using a flat blade screwdriver to help 
spread the end where it snaps onto the key lever.  Just a slight 
twisting motion with the screwdriver helps reduce the force needed to 
pull the keytop off. They snap back on easily.

Getting the top plate back on is tricky.  I've since seen a suggestion 
that you can make it easier getting all the keytops back in their 
respective holes by turning the keyboard upside down.  I'll try that 
next time (if there is one).

I'd also look at the possibility of being able to pull one keytop and a 
time with the top plate in place.  Anyone tried that?

Is there some cleaner that you could dump all the keytops into that 
would remove the white nasty and other dirt with much less elbow grease? 
  If so then one would have to evaluate the difference between easier 
cleaning and easier putting things back together.
