I would recommend following the teardown and making sure there is no liquid on the logic board. If there is, clean this with 95%+ isopropyl.
If the liquid is confined to the keyboard only, you can try cleaning the back of the keyboard possibly. It is possible it will be fine if it is just on the keyboard, but it could possibly cause some issues with keys in future, so it may be worth doing this.
There aren't any parts available for this at the moment (other than antennas and fans), and there are no proper guides on how to open this and clean/replace the keyboard. It may just be a case of checking the logic board for liquid, reassembling and hoping for the best :)
