I spilled my coffee all over my computer and made practically my entire keyboard sticky and was looking for tips on how to clean it.
Probably you best bet is to disconnect battery/power, strip it down, seperate the keyboard from the frame, ensure there is no corrosion on the main board or elsewhere, if there is take photos (just incase for later) and give it a dunk in IPA and a good scrub with a toothbrush
As for the keyboard your going to want to avoid using IPA or an ultrasonic style solution as these keyboards use a silver/tin conductive paint on a plastic membrane and IPA etc will strip this conductive paint clean off, you best bet is probably to submerge the keyboard in 40C distilled or deionized water and agitate the container
