Laptop mouse keys.

Hi all. Had abit of an incident last night a spilled a small amount of coffee onto my laptop, it wasn't alot, just a small amount on the touchpad and built in mouse keys, so i just cleared it up. However today my right moue key is sticking, are these keys easy to remove for cleaning? or are they unremoveable? As they dont appear to be attatched in the same ways as the keyboard keys are, they feel much more secure.
Thanks for the help guys.

 

Yes, I saw a service manual at Dell and there were only a few steps.

You don't want to get water in the electrics/electronics (or get sticky electrolytic substances on the electronics). If you are stuck I suggest you get some Contact Cleaner, set the keyboard in an upside-down position and flush the keys so that all the liquid runs back out. Leave it for many hours before powering it up.
