I've done this to several Amiga keyboards throughout the years from the 1000 to the 4000. Really not sure how they get sooooo funky (besides the obvious careless stuff), but Jiminy Christmas, when you tear apart a keyboard and realize it needs a shave... :lol:
Anyway, I've NEVER broken anything by carefully prying the key out of its switch post - using just my fingers. First though, remove the keyboard from its shell so you can get a decent grip on the outer keys and work your way in until you've got everything removed. Couple of springs on the spacebar and stabilizers (Return and shift keys too) to be aware of.
I usually fill my sink up with some dishwashing detergent and let the keys soak for a bit. Can use a wash cloth with the same detergent to clean the case/shell. Wash cloth for the keys and maybe even a toothbrush if they're really bad.
As for the switches or a membrane, just use electrical contact cleaner and be sure to wipe up the excess. Black metal assembly, just use something like Fantastic and a Q-Tip or toothbrush to get around everything. I usually do not like to use glass cleaner or Fantastic on the outer shell as it can sometimes mar the surface. Or on keys for that matter as you can sometimes remove the lettering on 'em! Dish detergent is the safest and best all around bet I've found.
