I acquired an eMac 1Ghz that was pretty smokey. Girlfriend's aunt smoked a lot in front of it. I cleaned it like CRAZY, the shell a ten minute shower mixed with magic erasers. It all pretty much went away.. If I could get the grille off in front to clean the speakers I would be pleased. I may have to take apart a lot more to access the speakers by the looks of it.. The computer is quirky, I think it needs a new battery.
