I would think that the (acid ) in the bile would do the most damage on the electronics under the keys?(sticky keys)
I would replace the keybourd but if you take it apart look for traces of corrosion around terminals.
Iwould probably take it in to a reputable service company and just tell them what happend you anrt the first.
Ps .
Still looking for that algae/weed?
