Mysterious stain on the sides of the third row

[Nytimes770]

Looks like a seat/vinyl cleaner that was over sprayed and not cleaned off because it seemed just wet but once it dried later left a residue however it is an odd pattern for a spray nozzle and there is nothing on the seats. Have you done the car wash yet?

Its at the dealer. The leak specialist will be looking at it

Did you ever figure this out? My wife just sent me a similar picture, but on the back hatch plastic. I'll check it out at lunch and see what I can find.
