I'm sure time is a huge factor in such cases.

IME with several keyboards, distilled water is unnecessary. Just use
really hot water, and use it long enough to make sure that any sugar or
salt is completely eliminated -- something like dishwashing detergent is
fine, too, if there's any grease in there. There's nothing in the
keyboard that will be damaged by water in the time it takes to really
rinse it out thoroughly *provided it's dry again before power is
applied*.

Most contemporary keyboards are comprised of three sheets of plastic
with conducting traces silkscreened on them. If the liquid is corrosive
(orange juice, most sodas), you have to move quickly to get the stuff
diluted before the conducting layers are eaten away ("quickly" means do
it today, don't wait until the weekend).

Then give it enough time to totally dry out. It can take quite a while
for water in between those plastic layers to completely evaporate.
Holding the keyboard by one end and vigorously swinging it around
(outside is best), can get most of the water out fairly quickly. Some
time in a *slow* oven will help; anything up to 200 F won't hurt things.

Taking the keyboard apart is a real pain, but usually possible if you're
careful. Be sure to take a photo of the keyboard *before* you remove all
the key caps.

Coffee stains don't seem to come off without scrubbing.
And if they get into small spaces between moving parts,
well, shall we say that in spite of signs asking folks
to NOT pour coffee in the sink, we still have to unclog
the drain about once a year (at work).

If a creamer is mixed in, the stain is glue-like and thicker.

Tea is MUCH worse than coffee.

What brand/grade of coffee are you brewing/drinking that clogs drains?

If you have coffee clogging drains, I'd advise you not to consume it!

This was a sink next to a coffee maker that served 50-100 people.
And I'm sure there were other things contributing to the problem.

The drinking fountain also--and that was clogged by coffee only.

Try not washing a coffee cup for a hundred servings
and see how thick it gets. Especially if you use creamer.
