I suggest you stop using your MacBook '''immediately''', disconnect the battery and charger until you can clean the logic board.
It's a typical story...
1) liquid spill
2) panic
2) Oh, it works! Panic over.
3) it stops working after 2-3 weeks
4) by this time most constantly energised power supply areas on the logic board are corroded beyond repair
You need to clean your logic board immediately. Good wash in hot water and 24h drying should be OK.
