Liquids creep between almost anything non adsorbent by capilliary
action. so you have to reverse this process.
The sure way is to put in a vacumn chamber at a temperature say 50 Dec
C, that will cause the liquid to boil out of the capilliary gaps as a
vapour. The vacumn has to have a stronger pull on the liquid than the
capilliary action holding it in. It might be propitious to get a price
for a replacement keyboard.
Something more risky would be to put it in an electric oven set to 70deg
C for 4 hours.
hotter than that might distort the plastic keys and the contact membrane
let alone the silicone rubber springs under the keys.
