I have yet to see a liquid damaged keyboard (that has shorted out and refuses to start) be repaired by cleaning with anything. Either the keyboard or the uppercase will need to be replaced.

What you need to do is disassemble your device, Retina MacBook 2015 Teardown and then use isopropyl alcohol to clean it more details on cleaning it: Electronics Water Damage
