Yellow liquid around/inside ps3 d-pad?

[Theminecraftaddict555]

Hello, everyone. One of my ps3 controllers that I dug up from a while ago has this strange sticky (likely dry) liquid around and inside the d-pad area. After some cleaning and wiping with some rubbing alcohol, the dried liquid seems to be have this yellow/orangish color and it doesn't seem to come off no matter how hard I try. Does anyone know what this mysterious liquid is? If so, is the liquid harmful or dangerous to the touch? I know, kind of a paranoid question. In my opinion, I suspect someone must have spilled some drink on it and it never got cleaned up but I can't be too sure.
