no wd-40 isnt a good lubricant (for certain tasks at
least) but it is supposed to be a penetrant. I had
thought that a subsequent wash of alcohol would remove
*it*. Im contemplating submersing it in a watered down
sudsy ammonia solution. Sudsy or probably even strait
ammonia is the BEST stuph that Ive seen for getting at
hidden crud, even better then acetone. You have to
soak it for a day or 2 though. But it reacts with
copper so Im concerned.

Supposed to be, but it's definitely not the best. My use of WD-40 is
reserved for anti-corrosive measures, and cleaning dirt and grease from
tools.... ratchets, wrenches, etc.
You don't need a penetrant, you need a solvent.

I don't think the alcohol would cut the WD-40 effectively, although, I
never tried it.

Where did you get this keyboard? How dirty is it? What kind of
construction is it? I normally clean keyboards with soap and water in
the kitchen sink, scrubbed with an old tooth brush, after it's been
dis-assembled as much as I dare. I then blow out as much water as I can
and stick it in front of a box fan. I've had one keyboard not work
after this process, However, it was an untested keyboard, so it may very
well have been toast to begin with.

It does depend on the quality of your water. Around here it more often than
not results in some keys having to be dismantled individually to get them to
work, as deposits in the water get left behind and stop the switches from
working. On some I've had it completely change the feel of the keyboard too,
presumably as deposits get trapped between sliding components (usually they
loosen up again with use, but not always)
These days I tend to pull keycaps off and wash separately if I can, or if not
use a suitable short brush / cloths and soapy water to try to clean the
keycaps without getting water inside.

I normally take them apart as much as _I_ dare, which may be a lot
further :-). In particular, I pull all the keycaps (after making a
diagram of their positions) and clean them with one of those foam cleaner
sprays.
In one case, where I had a lot of keyswitch problems, I even desoldered
all the keyswticthes from the PCB, took them out of the frame, took the
PCB off the frame too, and then took each switch apart and cleaned it.
That's a lot of work and may well not be worth doing in all cases.

The first time that you take off the space bar from the keyboard of a
5150, it's a little bit of a struggle mastering how to re-attach it.
I have a basket with a lid for cleaning them in a dishwasher.

that keyboard goes
like that :
Remove the 2 screws on the bottom. Take off the casing, disconnect the cable.
Pull off all keycaps other than the space bar
Bend the locking tab, then slide the bottom half of the keyboard assembly
to free it from the top half
Separate the halves, remove all the 'flaps'
Dismantle the space bar
Remove the screw holding the PCB to the bottom plate, free the PCB from
the keyhole slots/studs, remove it.
