Just opened my board with Gateron yellows pre lubed. The blue ones aren't lubed. I found similar marks all over the keyboard. Can these marks be dangerous and how do I deal with them?
They seem to be under the transparent plastic sheet on which the switches are mounted. I think it has foam underneath.
I'm guessing it's the lube slightly leaking out. I mean I wouldn't eat it. It's probably not going to short circuit anything and damage the board. It would be a foolish choice to fill keys with conductive lubricant.
