Keyboard Issues after Drink Spill

I wanted some advice on what to do after spilling a Yerba Mate (sugary caffeinated, carbonated drink) all over my MBP keyboard. I wiped off the keyboard immediately after the spill, but some of the liquid seeped below the keys and they're now a bit sticky and hard to depress.

Aside from this, I have regular keyboard issues where none of the keys work for about 1-2 minutes. This happens a couple of times every week.

Any DIY solutions would be appreciated, as well as input on what Apple could potentially do if I took it in to the store.
