It was in a Yoomee Folio case and covered by a screen protector.
I wish I had taken a photo of what it looked like before wiping things off. Suffice it to say that the screen was completely beaded with the KY Jelly and the inside surface of the folio case was soaked. There was some seepage to the back cover of the tablet.
I was able to wipe off most the lubricant. The case itself is sticky and being porous, I think it will be a loss. The front is covered by a residual film of KY that I can't seem to wipe off. I'll probably just have to take off the screen protector and replace it, but considering it took 2 screen protectors to get a perfect application, I'd prefer not to do that. The back cover is still a tad slippery.
What's the best way to get KY Jelly off your Nexus 7?
