My system got wet!

Anyone got a solution for this?

My Mac got some water and it didn't turn off right away - I did it myself asap.

I let it to dry and, in the next day, I tried to turn it on, but it didn't. I also connected it to the charger and no light (either green or orange) poped up.

Now it's the day 4. I connected the laptop to the charger and the light poped up, but I tried to turn it on and nothing...

Any advice?
