Treatment for a sticky keycap?

[Jellyfishpudding]

I have an X-Slim keyboard by i-Rocks and the B key has decided to start sticking. It pops back up on its own as if something sticky got underneath it. Are the keycaps easily removeable on these types of keyboards? If so, should I just try to clean underneath it? I don't want to pop it off unless I know it'll snap back on.

Thanks!
