It's late and I need some help so please forgive my brevity. I'm house sitting at a friend's place and was playing his new(ish) Stranger Things game, some sticky oil or sauce or some other liquid debris got on the playfield. I only started to notice when the ball was hanging up in one spot and when I investigated, there was some kind of sticky substance all over a significant part of the right playfield. It sticks to the touch and in some places there's active dark goo.
Is this a known problem with oil leaking from some mechanism or something? I think it's the Premium version if that helps.
I tried removing it with some napkins, but it hasn't worked. Is it safe to use dish soap and water?
I'm looking for some quick advice because my friend and his gf get home tomorrow and I need to get this cleaned up before they get back (or conversely, be able to point to a known defect with these models to explain).
