How to clean a macbook pro keyboard after a spill

Recently ordered a torc screwdriver to see if I can clean off the drive with some isopropanol, but not sure if I should replace the keyboard or not. I think there is still a rice piece stuck under the optical drive, but don't have the correct tools to pry it out yet. Took a few hours to get the rice out that had seeped to the internals of the machine. Tried further drying by setting rice over the keys for a few hours, which was a mistake. Currently is powered off and upside down with a small cooling fan on the keys. However the computer does not sound as if it's working too hard, no overpowered fan noise, just operating normally. No response at all from any key, and the backlight only appears to be working in the very center of the board. Powered the laptop on the next day and everything works except the keyboard. Left the computer upside down for about a day to dry out some more (powered off) and popped off and cleaned the keys that weren't working with a damp cloth (water - dried thoroughly before popping back in place). The machine was bone dry inside, dust undisturbed with the only oddity being a slight coffee smell coming from the optical drive corner (drive was a little hesitant to release disk inside - took 2 tries to eject disk), but no smell anywhere else. Turned it back on (which I now realize wasn't the wisest move, and I'm very lucky nothing got fried) and everything worked, so I put it to sleep and left it while I went to work.ДЄfter work (about 5 hours later) I found the keyboard keys weren't working right (no response to occasional response from enter, spacebar and delete keys, and one of the directional keys seemed to be constantly active - computer making bumping sound like incorrect key pressed), so I powered the laptop off and opened up the back to see if there was any liquid inside.

Immediately set aside the computer and dried most of liquid off, then turned the machine off and more intensively dried with a cloth.

Spilled coffee with sugar and milk on the right side of the keyboard on my macbook pro.
