|The proper way would be to clean it. At the factory they basically use a large dish washer to clean all the parts in warm distilled water and special soap and then they dry it with warm air.|
You can try to take it apart and see how far the damage is. Might be only keyboard needs to be cleaned. Use distilled water and have a blow dryer to dry it.
Otherwise take it to a repair center. I doubt it would be covered unless you purchased a secondary warranty from the seller that covers everything. Every place tries to sell the extended warranties. If you bought one then see if it covers any damage.
