How can I clean the keyboard?

MacBook Air 11" Model A1370

I spilled coffee on my Macbook Air 11" (mid 2012 model), terrible I know. It actually wasnt much coffee, and I immediately turned it upside down and dried it all up. It didnt shut off or anything, and didnt even act weird afterward. The problem is that now (a few days later) the space bar and command key to the left of it are a bit sticky and they both smell like coffee (especially if I blow on them). So clearly there is some gunk under there. Should I take it all apart and clean it? Or try to take the keys off without taking apart the computer? I would like to clean it up so its no longer sticky, so really I just would like to know which tools to use and if its worth it.

Thank you!
