Got egg yolk underneath my keyboard.

Ugh. Help! I just got a bit of egg yolk under some of my keyboard keys. they seem like they're fine but I'm just scared that they"re going to stop working. I immediately wiped down my keyboard with a damp cloth and everything seems okay but you can clearly see the yellow colour under the backlit keyboard. I don't know what to do! Is there anyway to get most of it out?
