I have crayon all the non shiny black parts of my playstation four (it's a long story, and not important for the sake of this question). Anyway, now that it's there, I'm wondering the best way to get it off. Would it be baking soda? I tried a wet toilet paper roll and that didn't work. Also, does crayon on a playstation four pose that much of a risk to my disks or to the the actual drive inside of it. It's pretty worn down now, so maybe it's a non-issue. Two questions are best way to get it off, and risk assessment (maybe if baking soda poses more potential damage it's just better to leave it on).
Update: In terms of on-screen stuff it seems to be running fine. When I listen to it, I can hear stuff going on, but that might have always been going on I just never paid attention to it before.
