I use alcohol, windex, fingernail paint remover and other noxious things to
clean apple][ cases, just avoid getting the nastiest of these solvents on
things like the little lite that says power, or the apple ][ logos on
monitors or the name badge at the top of the machine. I've also heard that
some people will dissasemble the computer leaving the empty shell, take out
EVERYTHING, and run the plastic case through the dishwasher, not using the
Heated drying cycle of course.

As for key repair, they are little plastic wedges that are shoved against
two vertically mounted contacts, counter forced by a small spring. You can
not remove the keys without damage. To repair a keyboard you have two
options, One, Replace the entire keyboard, or aquire a ][ for parts and
remove the keyboard from the unit, the contacts are soldered into the
keyboard cirucuit board. You can then replace the switch. The Key caps
can be removed. but you can't get to the switch of course without
destroying it, or desoldering it as a unit. I have manually recontructed
them before, but they never seem to work quite right once forced open, but
the do function enough to use as long as it's not an alpha charcter, or god
forbid the enter key.
