Remove batteries from remote, to avoid further damage caused from liquid on powered circuits.
Allow the remote with the cover opened to dry for few days. Ideally the remote should be disassembled and the internal parts treated with cleaning solution, or 70% isopropyl alcohol and water. If you do not want to disassemble just let it there to dry up.
If the remote does not work after that , it means that the liquid had damaged circuits.
In that case get a replacement remote.
