At this point depending on how much time you have, you can choose to blow dry them(using the cool air setting,
because once again hot air has the potential to warp your Keycaps)
or leave them to air dry which could take several hours.
There are some recommendations involving the use of isopropyl alcohol, but note that due to varying strengths,
there is a chance that this could potentially damage the paint on your Keycaps, which is why a damp cloth using
only water is the safest option(but not necessarily the cleanest).
