I normally wash PCBs. Warm soapy water followed by 'flushing' with
distilled water. Leave to dry somewhere warm for several days afterwards.
Remove any fans first, because motor housings make for great water
traps... the long drying time makes this unsuitable for some
situations, but it works a treat...

Which exactly what I have done for many years, but two things to be
aware of - don't wash hard disks not keyboards. Hard disks have
breathers which can let the water inside and many keyboards are
membrane types which can trap water under the membrane.


keyboards are one of the few thing which I would wash, but I would
completely dismantle it first (making sure I have a second one nearby to
make sure all the keys go back where they came from
